No exact locality is known for the type of this species, but I have 

 recently received a large adult female, captured by Messrs. C. L. 

 Leipoldt and E. Pattison on the Sneeuwkop Mt., in the Cedarberg 

 Eange, Clanwilliam Div., at a height of over 3,000 ft. 



This specimen closely resembles the type from which, however, 

 it differs somewhat in colour the interocular area of the carapace, 

 the upper surface of the hands, the vesicle, and the legs being dark 

 olive-brown instead of reddish yellow. The last sternal segment is 

 distinctly keeled on each side. Pectines with 16-17 teeth. Total 

 length 110 mm. ; length and width of carapace 14^ mm. ; width of 

 hand 12f mm. ; length of hand-back 9 mm. Basal joint of mandible 

 provided on the inner side with four obovate lamellae (modified 

 hairs), which are not present in the type specimens.
