Class ?. narrowed to a point at the tip; the males not having a strong joint at the extremity of the anterior tibia;,—constitute the fonowing genera:— Atypin, Latr., Oletera, Walck., having a very minute tongue, and the eyes placed close together upon a tubercle. Type, A. Sulzeri, Latr., Arnnea picea, Sulzer, about two-thirds of an inch long, and anteriorly of a blackish colour. This species burrows, in shelving ground, covered with turf, a cylindrical cell, curved below, lined with a white silken tube. The egg-case is affixed by silken threads attached to each end, to the bottom of this tube. It is found in the vicinity of Paris, Bordeaux, &c. M. Milbert has sent another species, found in the neighbourhood of Philadelphia. Eriodon, Latr., Missulena, Walck., has the tongue long and narrow, and the eyes dispersed on the front of the thorax. E. occatoriiis, Latr., from New Holland. C/(n;;«?/r(7, Dalm., has the eyes placed on a very elevated frontal tubercle; four of these (the two anterior being very large) occupying the centre; the external spinnerets are very long. Founded on a species observed by Dalman, in Copal. Fig. 29.—Atrpus Our second and last division of the quadripulmonary Spiders (or genus Mygale) is characterised, as in Eriodon, by a nan-ow tongue, prolonged between the maxillfe, and by 5-jointed palpi, but the hooks of the chelicerse are folded upon their inner face; they have six spinnerets ; the first pair of legs, and not the fourth, is the longest, and tlie third the shortest. Some have only six eyes. The number of their pulmonary sacs does not allow us to separate this subdivision from the preceding; as they lead to Drassus, Clotho, and Segestria, which have only two pulmonary sacs, the natural order does not permit us to pass from Mygale to the chasing S
