 Adult male, length slightly more than 1 line. 



In general appearance, form, and structure this species is of the ordi- 

 nary type, except that the caput is rather more roundly convex than 

 usual. The cephalothorax (looked at from above) is circular, with a 

 very straight prominent point at the middle of the fore margin ; its 

 colour is yellowish, margins black, and a longer black patch on each 

 side of the prominent point mentioned above, with some other blackish 

 markings on the clypeus, which projects forwards and in height equals 

 half that of the facial space ; the occiput has two blackish streaks, 

 which converge to the thoracic junction in a blackish spot. 



The eyes are eight in number, and form a nearly square figure, in two 

 parallel curved rows, or four pairs, of which the respective eyes are 

 contiguous to each other and placed obliquely ; the inner eye of each 

 of the two hinder pairs is, as usual in this genus, of an oblong form 

 and flattened, looking like a mere shining surface, but is evidently 

 an atrophied eye ; the outer eye also of each of the two fore pairs 

 is of an irregular form ; the outer eye of each hinder pair appeared 

 to be the largest of the eight and darkest-coloured, and strongly 

 margined with black on its inner side ; the inner eyes of the fore 

 pairs are also dark, and placed on a strong black patch ; the rest are 

 pearly white. 



The legs are rather long, tolerably strong, their length not very differ- 

 ent ; relatively it appeared to be (though this could not be ascertained 

 with certainty) 2, 1, 4, 3 ; they are of a rather paler yellow colour 

 than the cephalothorax, sparsely and obscurely marked with brown 

 blotches or broken bands, and furnished pretty thickly with hairs 

 (coarse bristly ones and others) and a few spines. Each tarsus ends 

 with a supernumerary or heel-joint bearing three claws. 



The palpi are similar in colour to the legs, except the digital joints, 

 which are yellowish brown ; they are moderately long, strong, and 

 thickly furnished with coarse hairs : the radial and cubital joints are 

 short and about equal in length and strength ; the former has no 

 apophyses at its extremity; the digital joints are very large, oval ? 

 and almost equal in length the whole of the rest of the palpus, or
