136 CONNECTICUT GEOL. AND NAT. HIST. SURVEY. ' [Bull. 



This species may be readily distinguished from the preceding 

 one by the biarticulate accessory flagellum of the first antennae ; 

 by the more slender first gnathopods of the male, the more 

 elongated carpus, and different form of the carpal process which 

 is narrowly triangular, acute, and with a small tooth near the base 

 of the posterior margin; by the less elongated propodus of the 

 second gnathopods; and the longer and more slender terminal 

 pereiopods. 



Length 6 mm. 



The species has been recorded from Norway, the British Isles ; 

 and Woods Hole, Massachusetts. 



Lembos Bate. 



Body slender, coxal plates of medium depth. 



First antennae much longer than second with flagellum long 

 and accessory flagellum well developed. 



Lower lip with mandibular processes strongly produced. 

 Mandibles with both incisive plates dentate, molar tubercle 

 strong ; third joint of palp longer than second. First maxillae with 

 inner plate small and bearing a single apical seta; second joint of 

 palp with several spine-teeth. Maxillipeds with plates generally 

 well developed; fourth joint of palp not stout. 



First gnathopods in male with merus not elongate ; carpus and 

 propodus stout, subequal in width, strongly setose, palm of latter 

 with tooth-like projections. First and second pereiopods glandu- 

 lar. Posterior pereiopods with basal joint not very widely 

 expanded. 



Third uropods with rami much longer than peduncle and 

 equal. Telson simple.
