spines showed a tridontate apex. First maxilliped having ver}- 

 numerous hranchial leaflets on the epipod, exopod very elongate ; 

 teroiinal joint extremely small, attached at inner front angle of the 

 preceding laminar joint. Second maxilliped with short but very 

 broad second joint, rather longer than the remaining joints, distally 

 narrowed, carrying a long feathered seta ; from the very short third 

 joint projects nearly at right angles a spine with a distally widened 

 spear-like end, microscopically ciliated, similar to that described by 

 Sars for C. macroplithabtms ; sixth joint not specially dilated, tipped 

 with two spines and carrying a short curved seventh joint, which 

 but for the attached muscles might pass for a spine. The third 

 maxillipeds have the much-curved second joint about as long as the 

 remaining serrate joints combined, the seventh joint very small. 



The first peroeopods are very like the third maxillipeds, but with 

 all the joints rather longer, and the fifth rather longer than the 

 sixth instead of the reverse. Second peraeopods with second 

 joint stout, not so long as the rest combined, the seventh rather 

 longer than the fifth and thrice the sixth. Third peraeopods with 

 second joint much narrowed distally, much longer than the rest 

 combined, while in the fourth pair this joint about equals the others 

 together. Fifth pair narrow throughout. 



Peduncle of uropods serrate on both margins, more strongly on 

 the inner, about twice and two-thirds as long as the endopod, which 

 has five spines on the inner margin and a terminal spine; the slightly 

 shorter exopod is almost unarmed. 



The carapace, of immature male, measured 3-3 mm. long, by 

 2"5 mm. broad.

 The specific name is applicable not only to the character of the 

 carapace but also to the close affinity between this species and the 

 Cavipylaspis (jlaber, described by Professor Sars, from Norway and 

 the Mediterranean. The sij^e, the shape, the mouth organs, and 

 even so particular a feature as the arrangement of pellucid spots 

 on the carapace seem to be in close agreement. On the other hand, 

 against identification of the two species may be set the following 

 differences. The South African species is rather larger, its carapace 

 is not quite smooth, its eyelobe is differently shaped and without
