Pedipalpi, Ricinulei, and Opiliones. 40, 



blackish; legs and antennae lighter reddish brown; palps yel- 

 low. 



The single male is 2.46 mm long and 1.47 mm broad, ce- 

 phalothorax 1.21 mm long, antenna? from the base of the trans- 

 verse keel 1.58 mm long, palp 1.58 mm, first leg 2.3 mm, fourth 

 leg 2.3 mm long. The female is about of the same size; its body 

 is 2.48 mm long and 1.41 mm broad. 



Remarks. Rather similar to species of the genus Siro, 

 but proportionately broader, with the legs a little shorter and 

 conspicuously thicker, and besides differing in the shape of 

 the front margin of the cephalothorax and in several important 

 features (shape of stomotheca, and of both pairs of maxillary 

 lobes, hairs on second antennal joint, etc.). 



Occurrence. The two specimens were captured in the 

 Island of Fernando Poo; the male at Punta Frailes in Oct. 

 Nov. 1901, the female at Basile in Aug. Sept. 1901 in an 

 altitude of 400 600 m.
