Corycodus bullatus A. Milne Edwards, Bull. Mus. Comp. ZooL, vol. 8, p. 23, 

 1880 (type locality, off Morro lighthouse, 175-250 fathoms; whereabouts of 

 type unknown.). — A. Milne Edwards and Bouvier, Mem. Mus. Comp. 

 Zool., vol. 27, p. 86, pi. 17, 1902. 



Diagnosis. — Carapace pentagonal, anterolateral border longer than 

 posterolateral. A long distance between base of cheliped and of 

 first ambulatory. 



Description. — Carapace covered with tubercles flattened at tip, 

 which tend to disappear on the median line and the rear, but are 

 very prominent along the anterior borders. Regions scarcely marked 

 except the cardiac region, which is small but limited by deep furrows, 

 very divergent behind, closer in front. Anterolateral longer than 

 posterolateral borders. Front very defiexed, its point bent between 

 the eyes to join the epistome. Eyes small. Lower part of carapace, 

 sternal plastron, and ambulatory legs covered with small tubercles 

 like those on dorsal face. A strong prominence tipped with a spine 

 on median line at base of external maxillipeds. A row of three 

 similar spines on basis and ischium of maxillipeds. A median promi- 

 nence at base of cheliped. Subhepatic region excavate. 



Merus of cheliped stout, subcylindrical, reaching to extreme line of 

 lateral border. Merus of first ambulatory slender. Fourth leg very 

 slender, not over half as long as carapace; merus longest, carpus very 

 reduced, propodus straight, considerably longer than the curved 

 dactylus. 



Measurements. — Female (18061), median length of carapace 5, 

 width 9, thickness at base of maxillipeds 4.6 mm. 



Range. — Off Habana, Cuba.

Genus CYCLODORIPPE A. Milne Edwards 



Cyclodorippe A. Milne Edwards, Bull. Mus. Comp. ZooL, vol. 8, p. 24, 1880 

 (part). — A. Milne Edwards and Bouvier, Mem. Mus. Comp. Zool., vol. 

 27, p. 94, 1902 (type, C. agassizii A. Milne Edwards). 



Carapace narrow in front and behind, lateral borders regularly 

 rounded, greatest width near the middle. Eyes very short and 

 closely placed in the orbit, the edge of which is not fissured. Anten- 

 nules very long and when folded cannot fit into the antennular cavity ; 

 antennal peduncles very narrow, flagella many-jointed. Buccal 

 cavity prolonged in a canal which attains the level of the front and 

 is divided almost to the extremity by the outer maxillipeds, the merus
