PHYLLOBTOMID^. 



Thiunb longer than the foot. Wings as in Stenoderma, but the 

 membrane between the fourth and fifth fingers is very curiously 

 marked by narrow transverse parallel bands of a dark colour, of 

 which about twenty-five may be counted ; also beyond the fifth finger, 

 for a distance of about half an inch inwards, similarly directed, but 

 double, bands traverse the wing-membrane. 



Wings extending to the metatarsus ; calcaneum rather more than 

 half the length of the foot ; interfemoral membrane well developed, 

 angularly but not deeply emarginate behind, the emargination ex- 

 tending slightly above the middle of the tibiae. 



Fur yellowish brown, the extremities of the hairs greyish ; a 

 conspiciious white spot on each shoulder at the origin of the ante- 

 brachial membrane ; wing-membrane between the humerus and 

 femur, and the interfemoral above, thinly clothed with soft fur. 



Upper middle incisors with a broad base and a very short cusp, 

 scarcely exceeding in vertical extent the outer incisors, which have 

 oblique cusps directed inwards ; first upper premolar short, trian- 

 gular ; the second premolar nearly equals the canine, and is in a 

 plane but slightly posterior to it ; upper molars very broad, the 

 conjoined antero-posterior diameter scarcely equal to the transverse 

 diameter of the first molar, the second molar but slightly smaller 

 than the first ; lower incisors extremely small, grooved ; first lower 

 premolar about half the size of the second, and three fourths its 

 vertical extent, with a straight triangular cusp ; second lower molar 

 about half the size of the first molar, triangular in cross section at 

 its base. 



Length (of the type, an adult 2 )> tead and body 3", head 1", 

 ear 0"-65, tragus 0"-3, forearm 2"-l, thumb 0"-5 ; third finger— 

 metacarp. l"-5, 1st ph. 0"-7, 2nd ph. 0"-9, 3rd ph. 0"-6 ; fourth 

 finger — metacarp. l"-35, 1st ph. 0"-55, 2nd ph. 0"-55 ; fifth finger 

 — metacarp. l"-4, 1st ph. 0"-6, 2nd ph. 0"*55 ; tibia 0"-65, calca- 

 neum 0"-25, foot 0"-4.

This most remarkable form stands alone among the species of 

 Chiroptera, and, indeed, in its peculiar and grotesque physiognomy 

 is unrivalled among known mammals. While resembling many of 

 the species of the group to which it belongs very closely in the form 

 of the teeth, in the general shape of the skuU, in the warts of the 

 lower lip, in the colour and peculiar markings of the fur, and in the 

 form of the extremities, it differs quite as remarkably in the pre- 

 sence of the peculiar characters described above. 



If, as I believe, Centurio m'-murtrii be identical with this species, 

 we have added to the other most remarkable peculiarities in struc- 



Cheiromeles torquatus, a species otherwise very widely removed. In Centurio 

 m'murtrii, Allen (which appears to me to be evidently the male of this species), 

 the central neck -band is similarly marked in the centre by a circular depression, 

 but is so yery large aa to cover the face like a mask when drawn upwards ; and 

 there are two other additional bands (probably reduplications of the integument 

 in the neighbourhood of the primary bands caused by their great development), 

 making five bands in all.
