A large species, easily distinguished by its carrying 

 the notogastral cast skins, and by the peculiar shape 

 of the posterior part of the abdomen. 



Colour. — Very dark chestnut-brown ; the whole 

 abdomen is, however, hidden by the cast skins, which 

 are usually mouse-colour. 



Texture rough, and dull in every part. There is 

 not an even or unbroken line in the whole creature. 



Cephalothorax very rough and broad, nearly as 

 broad as the progaster, from which it is marked off by 

 a deepish sulcation. The whole surface is covered by 

 irregular vermiform ridges. The cephalothorax is 

 thick and arched, with two broad raised lobes covering 

 the postero-median portion, and leaving a longitudinal 

 median depression between them. Rostrum broad, 

 blunt, with a trifid outline if seen when raised, and a 

 rounded outline if seen when lowered. Eostral hairs 

 short and curved. Pseudo-stigmata large and pro- 

 jecting, placed dorsally at the posterior angles. 

 Pseudo-stigmatic organs of moderate length, thick, 

 slightly clavate or thickened toward the distal end, 

 directed outward and backward. Interlamellar hairs 

 rudimentary. 



Legs thick and flattened, of moderate length, hind 

 pair scarcely reaching the posterior end of the abdo- 

 men, they are extremely rough. Femora broad and
