Hymenicoides carteri, sp. nov. 



The carapace is almost circular, emarginate at the base of the 

 last legs and with the posterior border short; it is broader than 

 long in the proportion of 21 to 20. The upper surface is greatly 

 depressed, with the grooves well defined, and is closely covered 

 with minute hairs. The margin is entire and upturned; anter-

 middle of the front a small tuft of hairs. The rostrum is entirely 

 absent. The basal segment of the antennule and the greater part 

 of the eve are visible in dorsal view.

 rowed anteriorly; its lateral borders are rather strongly curved 

 and, as in the genus Rhynchoplax , its anterior and posterior edges 

 are curved inwards (text-fig. 16). On the sternum behind the bases 

 of the external maxillipedes there is a semicircular ridge, concave 

 anteriorly, which bears a fringe of long hairs. The curious struc- 

 ture of the external maxillipedes has been referred to in the generic 

 description. There are long hairs on the inner borders and outer 

 surface of the ischium and merus and on both inner and outer 

 borders of the dactylus. The exognath bears a long fiagellum and,
