long hairs, which are densest on the narrow dark-brown lateral 

 margins. The abdomen has an oblong subcylindrical figure, 

 tapering a little to the spinners ; it is slightly convex above, 

 projects but little over the base of the cephalothorax, and is 

 clothed with hairs; the upper part is of a brown colour, obscurely 

 intermixed with yellowish white, and has some long black hairs 

 at its anterior extremity; the under part and the spinners, which 

 are cylindrical and prominent, have a yellowish-white hue, the 

 latter being tinged with brown. 



This spider, which was captured in the Island of St. Antonio, 

 is very closely allied to Drassus lapidicolens, but differs from it 

 not only in colour, but also in the relative length of its legs and 

 in the structure of its palpi and falces.

The eyes, which are unequal in size and seated on brown 

 spots, are disposed on the anterior part of the cephalothorax in 

 two transverse curved rows, whose convexity is directed forwards; 

 the anterior row, which is the less curved, is situated immediately 

 above the frontal margin, and the two intermediate eyes are 

 seated on a protuberance ; the lateral eyes of both rows are 

 placed on minute tubercles, and are wide apart, those of the 

 anterior row being the smallest of the eight. The cephalothorax 

 is short, broad, convex, somewhat oval, with two furrows on 

 each side converging towards a shallow indentation in the medial 

 line of the posterior region ; it is clothed with coarse, pale-yel- 

 lowish hairs, and is of a yellowish-brown colour ; a dark-brown 

 band passes from the eyes to its base, and a broad one of the 

 same hue extends along each side. The falces are short, strong, 

 subconical, and vertical ; the maxillse are nearly straight, power- 

 ful, and greatly enlarged at the extremity, which is obliquely 

 truncated and protuberant on the inner surface ; the lip is tri- 

 angular; and the sternum is oblong heart-shaped, hairy, and 

 has eminences on the sides, opposite to the legs. These parts 

 have a dull brownish-yellow hue. The legs are very unequal in 

 length, the first pair being much the longest and most robust ; 

 the fourth pair surpasses the second, and the third pair is the 

 shortest ; they are provided with hairs, and the metatarsus of 

 each posterior leg has a calamistrum situated in a curve at its 

 superior surface ; the femora, genua, and tibiae of the anterior
