curved claws, toothed at the base, and has hair-like papillae on 

 its inferior surface ; the fourth pair is the longest, then the first, 

 and the second pair slightly surpasses the third ; the palpi are 

 short, supplied with hairs and spines, and have a curved claw at 

 their extremity. These parts have a dull brownish-yellow hue, 

 the lip and sternum, which are the darkest, being tinged with 

 red. The abdomen is oviform, convex above, projecting over the 

 base of the cephalothorax, and is thinly clothed with hairs : it is 

 of a pale dull brownish-yellow colour ; at the anterior extremity, 

 close to its junction with the cephalothorax, there is a transverse, 

 curved, dark-coloured mark, thickly covered with long black 

 hairs, whose convexity is directed upwards ; a longitudinal soot- 

 coloured band, which Is bifid at its extremity, and of a dulL 

 brownish-yellow hue in the medial line of its anterior part, ex- 

 tends nearly half the length of the upper part ; to this band a 

 series of rather obscure, soot-coloured, angular lines succeeds, 

 which diminish in extent as they approach the spinners; their 

 vertices are directed forwards, and their extremities are con- 

 siderably enlarged ; the sides are marked with oblique bands of 

 the same hue, the anterior one being much the broadest ; and 

 there are a few small soot-coloured spots on the under part ; the 

 two inferior spinners are rather the longest, and cylindrical, and 

 the two intermediate ones, which are biarticulate, have the basal 

 joints united throughout their entire length, but the terminal 

 joints are free and divergent ; the sexual organs are moderately 

 developed, of a dark red-brown colour, and have a short, obtuse, 

 pale process connected with their anterior margin. Some indi- 

 viduals are paler and less distinctly marked than others, the 

 dark-coloured lines being represented by rows of spots. 



Drassus Paivani appears to occur in much larger numbers on 

 the Great Salvage than any other spider. There were forty-nine 

 females in the collection, either in an adult or immature state ; 

 but it is a curious fact that it did not contain a single male. 



1 have much pleasure in connecting with this fine Drassus the 

 name of that distinguished naturalist, the Baron de Paiva, to 

 whose liberality 1 am indebted for the interesting particulars 

 comprised in this communication, relative to the spiders found 

 to inhabit the Salvages.
