largest and darkest of the eight ; the convexity of the posterior 

 row is directed forwards, and the two intermediate eyes are 

 rather nearer to each other than they are to the lateral eyes of 

 the same row ; the lateral eyes of both rows are separated by a 

 wide interval. The falces are powerful, conical, convex at the 

 base, and vertical; the maxilla? are convex at the base, hollowed 

 on the inner side, and strongly curved towards the lip, which is 

 longer than broad and rounded at the apex. These parts are of 

 a dark-brown colour tinged with red, the falces being the darkest, 

 and the extremity of the maxillae having a yellowish-white hue. 

 The sternum is short, oval, hairy, and of a yellowish-brown 

 colour. The legs are robust, provided with hairs and spines, 

 the latter being most numerous on the tibia? and metatarsi of 

 the third and fourth pairs; they are of a yellow-brown colour, 

 marked with a few obscure soot-coloured spots, the metatarsi 

 and tarsi, which are the darkest, being tinged with red; the 

 fourth pair is the longest, then the first, and the third pair is 

 the shortest ; the tarsi are supplied with hair-like papillae on 

 their inferior surface, and are terminated by two curved, pecti- 

 nated claws. The palpi are short, and resemble the legs in co- 

 lour; and the digital joint, which is provided with strong spines, 

 has a curved, pectinated claw at its extremity. The abdomen is 

 oviform, densely clothed with hairs, convex above, and projects 

 a little over the base of the cephalothorax ; it is of a dull yellowish- 

 grey colour, with a broad band of black hairs curved round its 

 anterior extremity, and extended along each side in an irregular 

 line more or less interrupted ; from the middle of the curved 

 band an obscure, longitudinal, brown band extends, which tapers 

 to its posterior extremity; and on each side of it there is a 

 series of irregular black spots that become confluent as they 

 approach the spinners, which are cylindrical, prominent, and of 

 a pale red-brown colour, with a black line on the sides and under 

 part of their base ; the sexual organs are moderately developed, 

 and have a red-brown hue, that of the branchial opercula being 

 yellowish brown. 



The male is smaller than the female, but it resembles her in 

 colour. The radial joint of its palpi is rather smaller than the 

 cubital joint, and projects a straight, pointed, dark-brown apo- 

 physis from its extremity on the outer side ; the digital joint is 

 oval, convex, and hairy externally, concave within, comprising 

 the palpal organs, which are moderately developed, rather pro- 

 minent, with a slender, curved spine on the outer side, and two 

 processes at their extremity, the inner one of which is much 

 the smaller ; their colour is red-brown. 



One male and four females of this species were taken in the 

 Island of St. Jago, and three females in the Island of Fogo. It
