tarsus ol: the 1st, whereas in H. g'ujas the length o£ the carapace 

 slightly exceeds b )th these measurements. 



The foregoing species may be recognized as follows : — 



Males. 



a. Patella and tibia of 4tli leg longer than the same segments ol" the 

 1st leg: femur of 4th considerably longer than the width of 



the carapace crassipcs. 



h. Patella and tibia of 4th leg a little shorter than those of the 



1st leg ; width of carap ic9 about equal to the length of the 



4lh femur. 



a'. Carapace and head wider ; width of carapace equal to the 



length from the tubercle to the posterior border : widtli 



across head from cei)halic grooves equal to distance between 



fovea and meflian eyes laticeps. 



b'. Carapace and head narrower, width of former less than 

 distance between posterior border and tubercle ; and of 

 head equal to distance between tubercle and fovea gi9<is. 



Females. 



a. Posterior legs thicker, the tibia as wide as the patella or the 



distal end of the femur, its width very much exceeding a third 



of its length ; tarsus of palp a little inflated above at Die base. . . crassipes. 



b. Posterior legs thinner, the tibia thinner than the distal end of 



the femur, its width equalling about one-third of its length ; 



tarsus of palp not noticeably tumid above at the base. 



a'. Carapace very long, the area between the tubercle and the 



posterior median emargination noticeably exceeding the 



width, its total length about equal to that of the tibia and 



protarsus of the 1st leg ffi^o-^- 



b'. Carapace shorter, distance between tubercle and emarginatiou 

 not exceeding its width, its total length less than the length 

 of the tibia and protarsus of the 1st leg latwcps. 



Genus Eumenophoeus, nov. 



$ . Allied to Selenogyrus (cf. infra), with the procurved fovea, 

 and the legs long and slender, the 4th being longer than the 1st, 

 though their patellae and protarsi are equal ; so, too, are the tarsal 

 scopuL-B entire on the 1st, 2nd, and 3rd pair of legs, and divided 

 on the 4th. The following characters, however, point to generic 

 differences between the two : — 



(1) The legs are without spines, with the exception of a few at 

 the apex of the protarsi. 



(2) The posterior sternal sigilla are situated some distance from 

 the margin of the plate as in Selenocosmia, the pair in front of 

 them being also visibly away from the edge, the sternum itself 

 being as broad as long. Labium nearly as long as broad, its edge, 

 like the inner angles of the maxillse, densely granulate. 



(3) The claws of the legs are smooth and unarmed. 



EUMENOPHOEtJS CLEMENTSII, Sp. n. 



Colour a uniform mouse-brown. 



CaraiKice Hattish, broad, the width equalling the distance between
