ASSECLA HOLOTHUEICOLA, n. sp. 



Carapace broader than long, surface smooth and shining 5 the antero- 

 lateral and postero-lateral borders very nearly of the same lengths 5 front 

 broad, produced, broadly triangular, on a higher level than the antero. 

 lateral border, and .continuous with the superior margin of the orbit 5 

 anterior margin somewhat sinuous ; the antero-lateral border thin, 

 everted, five-lobed; second lobe the broadest; the free margins of the 

 lobes straight ; the angles slightly rounded ; the divisions separated 

 only by fine incisions; the gastric region of the carapace elevated; the 

 anterolateral parts much excavated. The lateral projection at the 

 junction of the antero- and postero-lateral borders more tooth-like than 

 lobular,and more projecting than the other lobes, thck andobtuse; ahigh, 

 prominent ridge running from its apex, at first, inward and slightly 

 backward, and then inward and forward on the swollen portion of the 

 carapace, terminating abruptly at the junction of the middle with the 

 lateral third of the breadth of the carapace ; a flattened, scarcely prom- 

 inent ridge anterior to and parallel with the preceding, terminating at 

 the bottom of the lateral sulcus. The prominent edge of the postero- 

 lateral border converging posteriorly. The post-orbital angle of the 

 first lobe not rounded, rectangular; a fissure on the superior margin of 

 the orbit near the external angle; the inferior margin entire, finely 

 granular; a fissure at the outer angle; the inner angle projecting as a 

 prominent tooth. Areolations on the surface of the carapace indistinct; 

 a shallow depression extending to the apex of the front, and on either side 

 of thi^ isa broad prominence (2 F and 1 M consolidated): 2 M and 3 M 

 consolidated ; 1 P slightly prominent. Central line of the body high 

 and convex, sloping toward the sides, which are concave. The first and 

 second joints of the external antennse cylindrical ; the apex of the 

 second joint on a level with the frontal margin. 



The third joint of the outer maxillipeds longer than broad; inner mar- 

 gin oblique; superior margin straight ; angles prominent; irregularly rect- 

 angular in outline, broader at the base than at the top. Inferior regions 

 finely pubescent ; the pubescence only seen under the lens. 



Hand strongly bicarinated on the superior surface; a well-marked 

 ridge on the middle of the external surface ; above the preceding is a 

 flattened, nearly obsolete ridge ; the inferior surface smooth ; a high 

 crest along the whole length of the upper edge of the movable finger; 

 at the base of the crest, on either side, is a sulcus, extending the entire 

 length of the finger ; the inner and outer surfaces of both fingers deeply
