THE PROPER BATS.

would be general, whereas the hair generally is black, and it is only the 

 points that are white, Their habitat is far from being ascertained, though 

 it is probably South America, as the individuals in the Leyden Museum 

 were discovered in a collection which was made in that part of the world. 

 The examination of those which have come to hand proves that they 

 were young, and probably the adult will be of much larger dimensions. 



75. V. PARVULUS THE LITTLE BAT. 



M. Natterer, of Vienna, captured this Bat in the Brazils, and deposit- 

 ed specimens in Austria and Holland. M. Temminck considers it as new. 

 It is less than the PipistreUe of Europe. The ears are small, straight, 

 pointed, with a very distinct lobe at the lower part ; the tragus too is 

 strai"ht, shaped like the willow-leaf, with an external leaf at its base ; the 

 muzzle is very short and obtuse, and there is a very large wart on the 

 lower lip : the interfemoral membrane is clad both above and below. The 

 fur is bushy, but not very long ; the superior parts are of a dull black ; 

 the sides of the neck, and lateral parts of the chest, are more dingy than 

 the back ; the front of the neck, and the mesial line of the abdomen, 

 and the sides, have the points of the hair brown ; an isabelle hue to- 

 wards the limbs. The total length is 2£", the expanse 7". 



76. V. .ENOBARBUS.— THE RED-BEARDED BAT. 



The size of this animal is much less than the PipistreUe of Europe, 

 and the expanse, especially, is very limited. The muzzle is short ; the 

 ears as broad as long, round at the point; the tragus is curved towards 

 the head. The tail is very short, and its delicate point is free ; the base 

 only of the upper surface of the interfemoral membrane is clad. The fur 

 is long, and bi-coloured throughout. Above, it is reddish-brown, the 

 base of the hair being black ; the forehead, cheeks, and chin, are red ; 

 the sides of the neck reddish ; the pubic region pure white ; the abdomen 

 whitish, the flanks light reddish, but in all these places the roots of the 

 hair are black. The total length is 2" 3"', the breadth 6£", (French.) 

 The habitat of this species is not ascertained, being grounded on a single 

 female specimen which was sent from South America. — (Fig. in Temm. 

 Mon. II. pi. 58, fig. 4) 



77. V. ARSINOE.— ARSINOE'S BAT. 



M. Temminck regards this as a new species, an old female having 

 reached Leyden from Surinam. It has the same dimensions and forms 

 as the Whiskered Bat of Europe. (See No. 8.) Its head is short and 

 depressed ; its muzzle obtuse j its ears conical, with a round point, and 

 no scooping out ; the tragus straight, and lance-shaped. There are six 

 molar teeth above and below, two of which, in each jaw, are false. The 

 fur is very short, smooth, and spare, and the membranes are totally naked. 

 The upper parts of the body are perfectly black and shining ; the lower 

 of a blackish-brown, the tips being fawn-coloured. The robe on the 

 flanks, and round the coccyx, are larger than on the chest, of a blackish 

 brown, tipt with white; this marking forms, round the body, a kind of 

 whitish grey. The total length is upwards of 1\", the expanse more 

 than 8". 



78. V. POLYTHRIX— THE POLYTHRIX BAT. 



This, and the preceding species, were transmitted by M. Auguste St 

 Hilaire from the Brazils, and were described by his brother, M. Isidore, 

 in the Ann. des Scien. Nat. t. 3. They are unaccompanied, however, 

 with figures, which is a great deficiency, so much so, as to leave some 

 doubt as to their being distinct from those described by the Prince de 

 Wied. However, they probably are. The size of this one is somewhat 

 greater than that of the PipistreUe. Its ears are small, larger than they 

 are broad, and scooped out at their external margin ; the body is nearly 

 as long as the arm and fore-arm ; the tail as long as the fore-arm only. 

 The interfemoral membrane is sparingly covered on its upper face with 

 hair; the face is much clad, being covered with very long hair; and only 

 the end of the snout is left naked. The superabundance of fur gives it 

 a remarkable and hideous appearance. The fur is soft, abundant, and 

 substantial ; above, it is of a very deep marone colour, and below, a 

 marone, slightly verging to grey. The total length is 3£", aud width 9", 

 (French.) There is a specimen in the Paris Museum. 



79. V. LEVIS.— THE SWIFT BAT. 



This second species, described by M. Isidore GeofFroy, from the Brazils, 

 's smaller than the PipistreUe of Europe, but is not less remarkable for 

 the large development of all its membranes. Its ears are nearly twice the 

 size of those of the preceding species, and its tragus is prolonged in near- 

 ly the same proportions, at the same time resembling them in shape. 

 The tail is as long as the body, and the interfemoral membrane is greatly 

 developed, almost equalling the length of the fore-arm. The face is sen- 



sibly less covered with hair than the Polythrix, and the interfemoral mem- 

 brane is scarcely at all clad. The colours are nearly the same as the 

 preceding. The total length is 2" 9'", the expanse 9". 



80. V. CHILOENSIS— THE CHILOE BAT. 



This species was discovered by Mr Darwin, in the recent expedition 

 of the Beagle, and has been described by Mr Waterhouse, in the "Zoo- 

 logy of that voyage." The colours and size of this species likewise 

 resemble the PipistreUe; whilst, at the same time, the wings are broader, 

 the fore-arm, leg, and tail, are longer, and the tragus is also longer and 

 straighter. The snout is obtuse, and supplied with numerous small 

 bristles. The forehead is concave ; the ears narrow and pointed, mar- 

 ginated externally, and supplied with four transversal folds ; the tragus 

 is long, filiform, pointed, and notched externally. A small protuberance 

 is placed on the chin, from which proceed a few radiating hairs ; the tail 

 is free at its point. The fur is of medium length, and of a beautiful 

 uniform brown colour ; it extends to the base of the interfemoral, both 

 above and below ; the rest of this membrane is naked and biack, as are 

 also the wings. The total length is 2" 1 J"', the expanse is 8" 3'". This 

 species was captured in the island Chiloe. — (Fig. in Zool. Voy. of the 

 Beagle, pi. 3.) 



These eighty species, which we have now discussed as amply as our 

 limits admit, include the whole number of those which M. Temminck, in 

 his late Monograph, considers as established on sufficient and satisfactory 

 grounds. To these he adds a short notice of many other species, of which 

 the original notices have been more superficial, and somewhat incomplete; 

 and as this information may be useful, under certain circumstances, to 

 many inquirers, we shall here give an abridgment of his valuable remarks. 

 To these, still following his guidance, we shall subjoin an account of ten 

 species, of which there are specimens in the Paris Museum, and which 

 were recently described by the late M. F. Cuvier, in the first vol. of the 

 Nouvelles Annates du Mus. d'Hist. Nat. And this accomplished, we 

 believe we have omitted nothing whereby we may bring our account of 

 this genus, as of those which have gone before, up to the level of the 

 most recent intelligence which has been accumulated upon this very ex- 

 tensive order. 



DOUBTFUL SPECIES. 



(European.) 



We adduce first the five European species which M. Brehm of Reuthen- 

 dorf pretends (we use M. Temminck's expression) to have discovered in 

 his immediate neighbourhood. He describes them in his Ornis, 3d No., 

 in these terms. The measurements are upon the scale of the Rheinland 

 foot : — 



1. Vespertilio Sobmurinds The ears are much shorter than the 



head; the upper canine has no conspicuous edge behind, so that the first 

 false molar is isolated, the second false is most conspicuous ; the two false 

 molars are tolerably long and pointed. The expanse is from seventeen to 

 eighteen inches. The upper parts of the body are brownish, the lower 

 light grey, passing into white ; the muzzle dark grey. It delights in the 

 hollows of fruit trees. This animal, M. Temminck says, may be a va- 

 riety of the Murinus. 



2. V. Wiedii. — Ears very small ; the free part of the tail 2 J'" long; 

 breadth of the wings medium size ; the fur long and silky; expanse from 

 15£" to 16". The upper parts of the body of a deep brownish-grey ; 

 the lower, light grey ; the muzzle greyish-black ; the membranes above 

 blackish-grey ; beneath, greyish-black. M. Brehm says, that this species 

 is very rare in his locality. It is not much smaller than the Myotis, but 

 is distinguished from it by its small ears, its narrower wings — by its long 

 fur, and peculiar marking. 



3. V. Okenii Ears small ; teeth large ; wings of medium size ; tip of 



the tail 3'" free ; fur of medium length, and soft ; above, brownish-black, 

 beneath, schiste colour. Expanse from 14 J" to 15". This is stated to 

 be somewhat less than the preceding ; the free tip of the tail is longer, 

 and the marking different. M. Brehm says it is rare. 



4. V. Ferrucineus The ears short, and roundly oval ; fur short, rust 



coloured; the wings very narrow; expanse from 15" to 15£". This ap- 

 pears to be only the Nociula, with a slight variation in the colouring. 



5. V. Schinzii The ears are 6'" long, and 2'" shorter than the 



head ; the tragus is long, and lance-shaped ; tip of the tail free, only a 

 J'", j wings broad; so long and soft, that the very short muzzle is en- 

 tirely hid ; the expanse from 9" to 10"; above, it is brownish-black,
