Head. rostrum strongly curved, lateral corners not projecting, evenly 

 rounded. Side-plate 1 very partially concealed, linguiform, slightly indented 

 at apex, 2^^ distinctly dentate on rounded distal margin. Pleon segment 3, 

 postero-lateral angles produced, but without tooth. Eyes large, oval. Antenna 1, 

 2*^jointshorterthan 1^*, 3<^ shorterthan 2**, flagellura 10-jointed, much longer than 

 peduncle. Antenna 2 longer than antenna 1, ultimate and penultimate joints of 

 peduncle snbequal. flagellura as long as peduncle, 14-jointed. Gnatbopods 1 and 2 

 rather feeble. not very unequal, 5*^ Joint with process densely setose, not 

 nearly reaching palra even in gnathopod 2, 6*^ Joint scarcely wider than 5***, 

 widening to well defined, denticulate, nearly transverse palra, finger minutely 

 spinulose ou inner margin, overlapping palra. Peraeopods 1 — 5 as in 

 G. bispinosa. üropod 3 reaching as far back as uropod 1, peduncle longer 

 than unarmed rami. Telson scarcely reaching beyond peduncle of uropod 3, 

 conically tapering, minutely tridentate. L. 9 5 mm.

Rostrum broad at base. Side-plate 1 very sraall, alraost concealed. 

 Antennae 1 and 2 rather slender. Mandible well developed, molar strong, 

 3"* Joint of palp shorter than 2*^. Maxilla 1, palp 1-joiuted. Maxilla 2, 

 inner plate shorter and broader than outer. Maxillipeds as in Gitanopsis 

 (p. 153), but palp more elongate. Gnathopods 1 and 2 rather feeble, not 

 very unequal, scarcely subchelate. Peraeopods 1 — 5. uropods 1 — 3 and telson 

 about as in Amphilochus (p. 149).
