UROPTYCHUS CAPILLATUS, new species. 



The rostrum is as long as the carapace; its breadth at the base is 

 ecjual to one-half of its length. The carapace is broader than long, 

 armed on the lateral margin with a number of spin- 

 ules; all surfaces are granular and covered with short 

 hair. This species is much nearer to U. 7'ugo8U8 ih?in 

 to any other in the collection; it differs in having a 

 dense coat of short hair where in rugoHus it is long 

 and scattering; the spines of the margin of the am- 

 bulatory legs are smaller and more numerous in cajj- 

 UlatHs; the upper margins of the propodal joints of 

 the ambulatory legs are spiny only on the proximal 

 half in rugosus. In this species the whole margin is 

 spiny. The chelipeds are wanting in both specimens. 

 Length of carapace, 3 mm. ; breadth, 4 nmi. ; length 

 of rostrum, 3 mm.

UROPTYCHUS GRANULATUS, new species. 



The rostrum of a large female is 5 mm. long, is l)road at the base, 

 and sharp at the apex. It is slightl}' depressed, in conformit}^ to the 

 curve of the convexity of the carapace; it is deeph' concave at the 

 base. The antero-lateral angles are armed with stout spines. Near 

 this is a smaller spine at the outer angle of the ])road and deep orbital 

 sulcus. The lateral mai'gins of the carapace are very strongly arcuate 

 and unevenly serrate. There is a spine on the margin behind the
