Pedipalpi, Ricinulei, and Opiliones. 



siderably longer than to twice as long as the first; the lower 

 margin without any process. 



The three posterior pairs of legs have the metatarsus di- 

 stinctly longer than the tarsus; first tarsal joint about one- 

 fourth as long again as the four other joints combined. 



The dorsal surface of the cephalothorax in the adult some- 

 what dark reddish-brown, with the impressions blackish, while 

 the abdomen is brownish-grey with the muscular impressions 

 dark and very conspicuous. Antennae, palps, and femora of 

 the legs somewhat lighter than cephalothorax; legs without 

 yellowish or Ught rings. 



Length of the body of a large specimen 8.4 mm, cephalo- 

 thorax 3 mm, palp stretched out 8.8 mm (claw included), se- 

 cond leg (coxa not included) 14.5 mm. 



Remarks. — C. ajricamis is allied to C. australianus L. 

 Koch, but is instantly distinguished in having the first tarsal 

 joint in the three posterior pairs of legs very conspicuously 

 longer than the four other joints combined. Furthermore adult 

 specimens of C. australianus have, according to Kraepelin, a 

 higher number of processes on both margins of the tibia of the 

 palps than is found in C. africaniis. 



Occurrence. — Taken on three of the Islands in the Gulf 

 of Guinea: Annobon, St. Thome and Principe. On Annobon 



6 specimens were taken in May 1902 in an altitude of 400 

 — 500 m, and i specimen in April in o — 500 m. On St. Thome 

 3 specimens were gathered in December 1900 at Agua Ize, 

 altitude 400 — 700 m, and 11 specimens in September — Octo- 

 ber 1900 at Visto Alegre, altitude 200—300 m. On Principe 



7 specimens were secured in Jan. — March 1901 at Roca In- 

 fante Don Henrique, altitude 100 — 300 m. — Adult specimens 

 from St. Thome are a little smaller than those from the two 

 other islands.
