The chelipeds are short, equal, and densely hairy on the 

 margins. The merus has a small tubercle on the upper mar- 

 gin. The carpus has the internal angle obtusely projecting, 

 with a small area of granules close to it on the upper surface. 

 The hand is short, very much compressed, its external surface 

 marked by a few rather coarse granules inclined to become 

 spinuliform ; the lower margin is strongly carinate, the carina 

 granulate, the upper margin is obtuse. The fingers are much 

 compressed, shorter than the palm, not meeting, except at 

 their tips, the mobile one sulcate, and with a cluster of 

 granules above at the proximal end ; the immobile one 

 slightly toothed. 



The ambulatory legs are moderately long, longer than 

 the chelipeds ; the first pair is shorter than the others, these 

 being sub-equal in length : all the exposed margins of the 

 joints are densely hairy : the propodi have longitudinal sul- 

 cations and some pits on their anterior and posterior surfaces ; 

 the dactyli are stiliform, and rather shorter than the propodi, 

 almost totally covered with short fur and some long hair. 



The pleon is fringed as the other parts, and scarcely 

 pitted ; seven-segmented, the basal segments not nearly cover- 

 ing the sternal plates : the first segment is drawn out to a 

 point on each side, and the terminal one shovel-shaped. 



Length of carapace, 12 mm. 



Breadth ,, ,, 16 mm. 



One female in the museum collection, which I describe as 

 belonging to the southern coast, on the strene:th of havins: 

 received from Mr. H. Flecker a carapace, which undoubtedly 

 belongs to it, from Edithburg, the type I received from the 

 Museum; locality doubtful.

 The integument is of firm consistence. 

 The carapace is broadly ovate or subcircular, smooth, 

 glabrous, convex in both directions, with the regions not de- 

 fined, ornamented with dark lines, which are chiefly meri- 

 dional, which extend below to the lateral regions, slightly 

 depressed between the gastric region and the front, also in 

 the metabranchial regions. Front advanced a little beyond 

 the eyes, about one-third the width of the carapace showing 

 arcuate above but depressed to a V shape between the fos- 

 settes. Lateral margins faintly defined. 



The sternal plastron is hairy at the border, which limits 

 the end of the pleon, and at the bases of the chelipeds.
