 the superior and inferior paire of antcnnic. The antenna; are 

 situated one above the other. The superior antenna} are long, 

 slender, and filamentous. The inferior antenna; are subequal with 

 the superior. The first pair of gnathopoda are more or less sub- 

 chelate ; the second also, and generally well developed. The 

 posterior paii" of pleopoda are never famished with hooks. The 

 telson is squamiform or tubular.

Cei)halon not produced mto a rostrum, but elevated into a crest. 

 Antenna? subeipial ; the superior \\'ithout a secondary appendage, 

 (•nathopoda subequal, subohelate. Four anterior coxa? as deejj as 

 their respective segments of the pereion, not nari'ow or pointed. 

 Three posterior pairs of pereiopoda short, subequal, having the 

 basa dilated at the upper posterior extremity, and narrowing with 

 a concave sweep to the lower. Posterior pair of pleopoda bira- 

 mous. Telson squamiform, divided.

Male. — Cephalon crested with four or five posteriorly curved trans- 

 versely flat teeth, excavate at the apex, the posterior being conihient 

 at the base with a dorsal carina. Pereion having the first two 

 segments elevated along the dorsal central line into a posteriorly 

 curved tooth ; the five following elevated into narrow tubei-- 

 clos, each being situated at the posterior half of its respective 

 segment, and ha-ving the lateral margins of all its segments curv(>d 

 outN\ards and upM'ard.s, so as to form a row of tubercles imme- 

 diately above the coxae. Pleon baring the first segment carrying 

 a dorsal carina-hke tubercle similar to the preceding ; second 

 and third segments baring the tubercles broken up into small 

 teeth curved and directed anteriorly. Kyes round, black. Su- 

 perior antenna; having the first joint of the peduncle armed (ii)on 

 the upper di.stal extremitj' with small ])osteriorly curved teeth ; 

 the second and third joints are narrower and .shortcM- limn the 

 first ; the flagellum is scarcely longer than the peduncle. Inierior 

 antenna"' longer than the superior. First i)air of gna'tliopiula 

 liiiriiig the propodos longer than the car])iis. long-ovale ; palm 

 tapering, scarcely as long as the inferioi' margin ; dactylos slender
