Rather sleuder and compressed. Frontal process short, not strongly 

 deflexed, apex of rostriim obtuse, scarcely reaching beyond middle ofl*** Joint 

 of antenna 1. Side-plate 1 distally expanded. Eyes rather small, roundcd, 

 dark red, at base of frontal process. Antenna 1 rather short, but longer than 

 peduncle of antenna 2, P* Joint longer than 2*^, flagellum subequal to peduncle, 

 10-jointed. Antenna2, ultimate Joint of peduncle slightlyshorter than penultimate, 

 flagellum subequal to peduncle. Maxiila 1, outer plate with 9 spines. Gnatho- 

 pod 1, process of b^^^ Joint very short, 6*'' Joint luuch widened towards the 

 well defined palm, which is much longer than bind margin. Gnathopod 2, 

 process of 5*^' Joint unusually small, scarcely reaching beyond middle ofhind 

 margin of large, oblong oval 6^1^ Joint, which wideus towards well defined 

 large oblique palm. Peraeopods 1 and 2, 2^ Joint beut, 6*^^ subequal to 5^^ finger 

 short. Peraeopods 3 and 4, finger rather more elougate. but not as long as 

 6*'* Joint. Peraeopod 5, 2*^ Joint piriform, last 4 joints subequal to one another. 

 Telson a little longer than broad, apical margin uearly straight or slightly 

 rounded, carrying 4 spinules. Colour pale yellowish; ova dark violet. L. 7 mm.

Frontal process not greatly produced, evenly curved, rostral apex 

 reaching apex of 1^* Joint of antenna 1. vSide-plate 1 subrectangular, little 

 expanded. Pleon segments 1 — 3 scarcely carinate. Eyes large, rounded 

 oval, bright red, at base of frontal process. Antenna 1 in Q reaching a little 

 beyond peduncle of antenna 2, 1^* Joint rather longer than 2<^, flagellum nearly 

 as long as peduncle, 11-jointed; in ö 1^* Joint of peduncle twice length 

 of 2<^, flagellum densely setose. Antenna 2 in d as long as body, ultimate 

 Joint of peduncle shorter than penultimate (equal to it according to Schneider). 

 Gnathopod 1, process of 5*'* Joint short, broad, not reaching palm, 6*'^ Joint 

 oval, palm well defined, about as long as bind margin. Gnathopod 2, process 

 of 5*^' Joint not more than reaching palm, 6*^^ Joint of even width, scarcely 

 more than tbrice as long as broad. Peraeopods 1 — 4, finger as long as 

 G*'» Joint; in peraeopods 1 and 2 6*^' Joint scarcely longer than 5*''. Peraeo- 

 pod 5, 5*^ Joint shorter than 4*'^ or 6*'\ Uropod 3, peduncle equal to 

 rami in length. Telson shortly oval, apical margin distinctly insinuate.
