PULMONARLC. 



According to Dufour Ann. des Sc. Phys., V. Ixxiii, 4 the 

 supposed male, of which I have made a M. cardeuse, 



differs from the preceding" individual in the Creator length of 

 its feet, in the hooks of the tarsi, which are t \viee the number 

 of the other, hut have,n/> spurs, and in the diminished length of 

 its mammillae. A more apparent character may he found in the 

 stout spine, whirh terminates, inferiorly, the two anterior tibiae. 

 This Mygale is found in the southern departments of France, 

 situated on the borders of the Mediterranean, in Spain, &c.

 vagesii, Dufour, Ann. des Sc. Phys., V, Ixxiii, 3; Aranea 

 Sauvagesii, Ross. The female is somewhat larger than that 

 of the preceding species, and of a light reddish-brown, without 

 spots. The exterior fusi are long. The four anterior tarsi are 

 alone furnished with small spines ; all have a spur at the end, 

 and their hooks have but a single tooth, situated at their base. 

 The chelicerae are stouter and more bent than those of the Cae- 

 mentaria ; the teeth of the rake are rather more numerous, and 

 th.-rc are two ranges of teeth under the first joint. The male is 

 unknown. This species is found in Tuscany and Corsica. There 

 is a small clod of earth in the Museum d'Hist. Nat. of Paris, in 

 which are four of its nests, forming a regular quadrilateral 

 figure. 



M. Lefevre who has made so many sacrifices to the science of 

 Entomology, has discovered a new species of Magale in Sicily, 

 the entire body of which is of a blackish brown. The extremity 

 of the anterior tibiae of the male does not exhihit that stout spine 

 which appears to be peculiar to the individuals of the same sex, 

 in the other Mygales. 



Another species is found in Jamaica M. nidulans figured, 

 together with its nest, by Brown in his Nat. Hist, of Jamaica, 

 pi. xliv, 3. 



There, the palpi arc inserted into an inferior dilatation of the ex- 

 ternal side of the jaws, and consist of but five joints. The ligula, at 

 fir>t very small Atypus lengthens, and then advances between the 

 jaws, and this character becomes general. The last joint of the palpi, 

 in both sexes, is elongated, and pointed near the end. There is no 

 .spur to the extremity of the anterior tibiae of the males.

The Atypi have a very small ligula almost covered by the internal 

 portion of the base of the jaws, and closely approximated eyes group- 

 u a tubercle.
