A. Seta articiili antennarum posticarimi secundi nuda. 

 * Styli caudales abdomine hreviores. 

 CoRYCJSUS HuxLEYi, n. s. Cephalotlioracis segmentum tertium supernfe visum breve, 

 angulis posticis productis. Conspicilla parvula, remotiuscula. AnteniiEe anticae 

 mediocres, setis longis ; antennarum postiearum articulus secimdus apice interne 

 bidenticulato, digito fere longior, seta longa, nuda. Abdomen 2-articulatum, seg- 

 mento primo paulo latiore et duplo longiore quam secundum. Styli caudales abdo- 

 mine duplo breviores, setis longioribus. 

 This species is nearly allied to Corycceus venustus, in vrbich species, however, as in 

 many others, Professor Dana has represented the fingar as consisting of only two seg- 

 ments ; in all the species examined by me, however, the usual three segments were 

 present, though, as is the case in the present species, and probably also in C. venmtus, 

 the basal is very short. 



Length yo oo^ts of an inch ; length of cephalothorax tooo"} of abdomen yzh) o^^^^ ^^ ^^ 

 inch. The first segment of the abdomen is -a^y", the second -^oqq', the lamella -^i^", 

 and the caudal setse ainn)" in length. The claw forms half the length of the finger. 

 Collected October 20. S. lat. 13° 43', W. long. 33° 55'.
