CANCROIDEA. 251 



is prominent. The anterior margin of 1M 2M, and 2L 3L, is 

 somewhat denticulate, and there are some ranges of granules, some- 

 times raised into ridgelets, on the surface of these areolets, and also 

 near the posterior teeth. From the posterior tooth backward the 

 margin hardly forms an angle. The tubercles of the large hand are 

 flat warts, and are not found on the lower half of the hand ; those of 

 the smaller hand are somewhat conical. Both hand and carpus are 

 without hairs. The eight posterior legs are sparsely hairy on the 

 margins of the fourth and fifth joints ; and the tarsus is short hirsute 

 in longitudinal lines or bands. The rnoveable finger of the large hand 

 has a large basal tuberculiform tooth. 



ERIPHIA SMITHII (M'Leay). 

 Singapore. 



Length of carapax of a male, one inch five and one-fourth lines ; 

 breadth, one inch ten and one-fourth lines; ratio of length to breadth, 

 1 : 1'3. The carpus and hands are covered with very small tubercles 

 or incipient spines, which are smallest and in part obsolescent on the 

 carpus of the larger leg. The figure of Krauss well represents the 

 species.

GENUS DOM.33CIA, Eydoux and Souleyet. 



This genus, although near Ruppellia, is singular in its very short 

 third joint to the outer maxillipeds. 



HISPIDA, Eydoux and Souleyet. 

 Coral reefs, island of Tahiti. 



The species collected by us in Tahiti, appears to be the same with 

 that described by Eydoux and Souleyet, Voy. de la Bonite, pi. 2, figs.
