Body with downy surface. Head, rostral projection minute, lateral 

 margins subtruncate, post-autenuai corners not produced. Side-plate 5, 

 bind lobe scarcely deeper than front. Pleon segment 3, postero-lateral corners 

 bidentate, the upper tooth the larger. Eyes large, reniforni, nearly meeting 

 at top of head, retaining colour in spirit. Antenna 1 of % length of body, 

 1^* Joint longer than 2*^ and '6^ combined, 2^ twice as long as 3^, flagellum 

 5 times as long as peduncle, with more than 62 joints. Antenna 2 much shorter, 

 ultimate Joint of peduncle a little louger than penultimate, flagellum more than 

 twice as long as peduncle, with 34 joints, 1*** longest. Guathopod 1, 5*^ 

 Joint much longer than 6*^, both fringed with varied spines, 6*^ Joint about 

 thrice as long as broad, palm convex, slightly oblique, finger not reaching 

 beyond it. Gnathopod 2 similar, but much longer, 5*'^ and 6*^ joints equal, 

 6*^ 5 times as long as broad. Peraeopods 1 and 2, 4*^ and .6*^ joints 

 equal, rather longer than 5**^, all spinöse, finger shoii, curved. Marsupial 

 plates very large in gnathopod 2 and peraeopod 1, smaller in peraeopod 2, 

 ^and small in peraeopod 3. Peraeopods 3—5, 4*^ Joint rather produced behind. 

 üropod 3, rami about once and a half as long as peduncle, serrate on inner 

 margin, with spines on both margins, apices acute, inner ramus with pectinate 

 inner margin. Telson longer than peduncle of uropod 3, longer than broad» 

 only slightly tapering, cleft ^/^ of length, the broad inward-sloping apices 

 each cut into 5 teeth. L. about 8 mm.
