stout spine, which 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, 8cc. 



M /orfi'ms, Walck. , Faun. Fran9., Arach., II, 1, 2;M. Saii- 

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

 vagesii, 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 chelicerse are stouter and more bent than those of 

 the Caementaria; the teeth of the rake are rather more numerous, 

 and there are two ranges of teeth under the first joint. The 

 male is unknown. This species is found in Tuscany and Cor- 

 sica. 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 Mygale in 

 Sicily, the entire body of which is of a blackish brown. The 

 extremity of the anterior tibiae of the male does not exhibit that 

 stout spine which appears to be peculiar to individuals of the 

 same sex, in the other Mygales. 



Another species is found in Jamaica — M. nidukms — figured, 

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

 pi. xliv, 3. 

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

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

 first 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. 



Atypus, Lat. — Oletera, Walck. 

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

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

 grouped on a tubercle.

 Body entirely blackish, and about eight lines in length. The 

 thorax is nearly square, depressed posteriorly, inflated, widened, 

 and broadly truncated anteriorly, presenting an appearance very
