Antenna 1 louger than head and peraeon; 2*^ Joint twice as long as 

 1^*, 3*^ very short; flagellum longer than pediincle, accessory flagellum small 

 (in figure). Antenna 8 nearly % as long as antenna 1, ultimate Joint of 

 peduncle shorter than penultimate, longer than flagellum, which is armed 

 with hooked setae. Guathopod 1 large, subchelate; 4*^ Joint small, narrow; 

 5th large, armed with a few scattered hairs; 6^*^ smaller (in figure much 

 smaller), irregularly quadrate, rather longer than broad, palm scarcely oblique, 

 deeply excavate, denticulate, defined by a triangulär tooth; finger stout, 

 denticulate, apex (in figure) reaching rather beyond the short palm. Gnatho- 

 pod 2 smaller; 5^^ and 6*^ joints subequal, with fascicles of setae along 

 bind margin; 6**^ Joint ovate (in figure oblong), twice as long as broad; 

 palm not defined, nearly transverse; finger stout, short, denticulate. Peraeo- 

 pod 2 longer than peraeopod 1 ; finger in both long, slender. üropod 3, 

 rami shorter than in uropods 1 and 2, lanceolate. Telson large, armed with 

 a few short hairs. L. 7 mm.

Back not much arched, pleon segment 4 as long as any preceding 

 segment. Head, lateral lobes somewhat produced, nan'owly rounded. Side- 

 plates 1 — 5 not very deep; 1^'' produced forward, 2*^ deeper than broad, 

 5*^ much broader than deep, nearly as deep as 4*^. Pleon segment 3, 

 postero-lateral corners rounded. Eyes round, rather large, a little removed from 

 lateral lobes of head. Antenna 1 as long as body, slender, 1^* Joint longer 

 than head, 2^ longer than 1^*, 3^ about ^4 as long as 2^; flagellum much longer 

 than peduncle, about 30-jointed; accessory flagellum with 2 joints, 1^* small,

 Joint of peduncle louger than penultimate or than the 8-jointed flagellum.
