body, also with fascicles of hairs on the under surface of the peduncle; 
flagellum with between 40 and 50 articulations. Gnathopoda rather small, 
subequal; carpus somewhat produced on its inferior surface; propodos 
ovate, with several transverse rows of spines on the infero-posterior 
margin; palm imperfectly defined; dactylos slender, smooth. Three 
posterior pairs of pereiopoda having the basa increasing in width. Ante- 
penultimate pair of pleopoda reaching to the extremity of the penultimate, 
smooth; penultimate pair with a few spines; ultimate pair with the rami 
about twice as long as the peduncle, thickly studded with short spines and 
fringed with long cilia. Telson divided to nearly half its length, with a 
minute spine somewhat remote from the apex at each side. Length :8 
inch. Semi-transparent in colour, with dark blueish spots.

Antenne subequal; superior without a secondary appendage. Mandibles

Cephalon produced into a small, acute rostrum between the bases of the 
superior antenne. Eyes oblong-reniform. Two posterior segments of the 
pereion and two anterior segments of the pleon produced dorsally into two 
teeth. Antenne about as long as body.  Peduncle of the superior pair 
about one-fifth as long as the slender flagellum ; basal joint very short, 
buried in front of the cephalon, second joint stout. Gnathopoda small. 
First pair very long and slender; carpus and propodos subequal, linear ; 
daetylos minute, transverse. Second pair short; propodos expanded above, 
palm obliquely transverse, defined by a tooth. Three last pairs of pereio- 
poda much longer than preceding; their cox: with comblike teeth on their 
posterior margins. "Third segment of pleon with the sides produced pos- 
teriorly, and ending abruptly in a serrated margin (almost smooth in young 
specimens). Posterior pair of pleopoda reaching to the extremity of the 
penultimate pair. Length about *8 inch.
