26 Studies on Arthropoda. I. 



the distal part of second segment is produced into three pro- 

 cesses, but the two drawings (figs. 2 g and 2 h) may convey a 

 sufficient idea of the curious shape of the whole part. 



In the male the body is 4.4 mm. long, second leg 7 mm. ; 

 in the female the body is 4.7 mm. long, second leg 6.9 mm. 



Remarks. C. crassipalpe is easily separated from the 

 other species hitherto known of the genus in having the body 

 and most of the legs covered with very broad scales, which are 

 not much longer than broad or almost as broad as long. 



Occurrence. Island of Fernando Poo, at two places: 

 Musola, altitude 400 500 m., January 1902, 2 males, 3 females, 

 i immature specimen; Basile, altitude 400 600 m., August 

 September 1901, i young specimen. 



Distribution. The specimens described by Hansen and 

 Sorensen were from Kameroon, the part of the continent oppo- 

 site to the Isl. of Fernando Poo.

A. Adult Female. 



Closely allied to C. Afzelii Thorell as described by Hansen 

 and Sorensen, so that it max be advisable to lay special stress 

 on the differences. 



Cephalothorax slightly longer than broad. Its surface is 

 adorned with numerous moderately large granules conspi- 

 cuously lower than high and of a special structure, as their 

 outline is circular, the upper surface very moderately arched, 

 marked off from the sides by a sharp outline, very finely stria- 

 ted, and besides very dark coloured, brownish black, while 

 the sides of the granules are greyish; between the granules a 

 number of feebly clavate hairs somewhat or considerably lon- 

 ger than the height of the granules; the whole adornment of 

 the surface differs from that in C. Afzelii in having the granules
