tooth of the orbit. This last is narrow, sharp-pointed, is directed 

 forAvard, its outer margin nearly straight except near tip. Two 

 antero-lateral teeth, small, thick, blunt, the first pointing forward, a 

 very small sinus between it and orbital tooth, outer margin convex ; 



the second tooth pointing out- 

 ward, its anterior margin 

 straight and almost trans- 

 verse, posterior margin convex.

y, jQ composed oi small, unequal 



tubercles. Outer lobe of sub- 

 orbital margin transverse and slightly convex; inner lobe oblique, 

 largely covered by pterygostomian lobe in ventral view, its outer 

 portion a little convex, inner angle a small, sharp spine; pterygos- 

 tomian lobe more produced than orbital lobe, arcuate, margin a little 

 oblique, forming an obtuse angle at inner extremity. 



Chelipeds of male not known, of female very slender, subequal. 



Merus joints of ambulatory legs rather slender, very rough; one 

 or two of the more proximal spinules of the anterior margin are out- 

 £:tanding; the distal lobe is triangular and acute, and in the first leg 

 has a long, sharp tip; anterior lobes of carpus inconspicuous; dactyli 

 long and narrow, their posterior margins proximally straight.

 carapace 5.8, width of same 7, length of second leg 13.7 mm.

 (type-locality, Charlotte Harbor, 50 fathoms; holotype. Cat. No. G492,

Diagnosis. — First antero-lateral tooth distant from orbital tooth. 

 Supraorbital teeth triangular. Tubercles above posterior margin 

 linear. Outer suborbital lobe subtruncate. Distal lobe of merus of 

 ambulatories sharp ; lobes of carpus well developed. 



Description. — Carapace covered with definite tubercles which are 

 ornamented with much finer granules than those elsewhere on the 

 carapace. Front with four Avell-marked rounded lobes, median sinus 

 deeper and wider than lateral. Two supraorbital teeth triangular, 

 subacute, outermost sinus broader and a little shallower than the 

 others; outer orbital tooth long, triangular, acute, outer margin
