latns also by its almost glabrous ambulatory legs; the 

 inner surface of the palm of the anterior legs of the male 

 is almost entirely clothed with hair in Heterogr. crenuhtus^ 

 whereas in Ileterogr. nudua the base of the fingers only is 

 hairy , as in Heterogr. penicillatus. The ambulatory legs , 

 especially the dactylopodites , are likewise more slender in 

 the species of Guerin , than in Ileterogr. nudus , if Dana's 

 figure is correct, 



I must, finally, observe that Kingsley (Proc. Acad. Nat. 

 Scienc. of Philadelphia, 1880, p. 208) is quite wrong in 

 uniting Heterogr. nudus with Heterogr. sanguineus de Haan , 

 for in this latter species the hands are quite naked , with- 

 out a tuft of hair on the inner surface , the wrist of the 

 anterior legs presents an acute tooth at the inner angle, 

 and the meropodites of the ambulatory legs are armed with 

 a sharp tooth at the distal end , whereas those of Heterogr. 

 nudus appear to be unarmed. 



Heterogr. maculatus M. E. may be identical with Heterogr. 

 sanguineus de Haan. Heterogr. crassimanus Dana also may 

 be identical with the species of the » Fauna japonica", but 

 the merus-joint of the outer foot-jaws appears more enlarged 

 and more dilated externally , with a more convex outer 

 margin in the species of Dana , and the penultimate joint 

 of the abdomen in the male is shorter in proportion to 

 its breadth. Moreover, in Dana's figure, the carpus of the 

 anterior legs does not present the sharp tooth at the inner 

 angle, which exists in Heterogr. sanguineus.

 This rare species may be easily recognized by the charac-
