ASSECLA HOLOTHUEICOLA, n. sp. 



Carapace broader than long, surface smooth and shiuingj the antero- 

 lateral and posterolateral borders very nearly of the same lengths ; front 

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

 lateral border, and continuous with the superior margin of the orbit ; 

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

 everted, flve-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 

 an tero lateral 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 and obtuse; a high, 

 I 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 

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

 1 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 this is a 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 autennoe 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
