CANCROIDEA. 245 



seriatis, superioribus paulo elongatis et acutis, digito rnohili spinidoso- 

 granulato, pollice perbrevi. Pedes 8 postici valde compressi, minute 

 velutini, rnarginibus liirsutis. 



Carapax very much convex, suborbicular, anterior regions faint areo- 

 late, areolets plane, granulose, 2 M not subdivided, granules naked, 

 interstices and sulci with an extremely short velvety coating ; front 

 a little projecting, emarginate ; antero-lateral margin arcuate, almost 

 entire, very faintly four-lobed, lobes minutely denticulate ; postero- 

 lateral margin much concave. Anterior feet stout, hand having an 

 edge above, surface set with granules, the granules above somewhat 

 elongated and acute, subspiniform, moveable finger spinuloso-granu- 

 late, thumb very short. Eight posterior feet much compressed, 

 minutely velvety, margins hirsute.

Dredged at Lahaina, Island of Maui, Hawaiian Group. 



Length of carapax, six and a half lines ; breadth, eight and a half 

 lines; ratio of length to breadth, 1 : 1-3. The velvety coating is 

 shorter than the granules, which are naked and polished, and quite 

 small. The antero-lateral edge does not appear to be lobed, except 

 when carefully examined. The female abdomen is velveted, except- 

 ing the middle portion; the outer maxillipeds are naked. The 

 granules of the hand cover closely the under surface, which, as well 

 as the lower part of the outer surface, is otherwise naked. The tarsi 

 are very hirsute on all sides. Each of the fingers has a tuft of hairs 

 a short distance from the tip, and the tips are blunt and only imper- 

 fectly spoon-like. The areolets 2 L, 3 L are not separate ; 5 L, 6 L 

 are separate. 3 M is not divided. The surface of the carapax against 

 which the posterior legs rub is very broad and smooth, and forms an 

 angle with the upper surface of the carapax.
