Decapod Crustacea of Bermuda, Part II. 135 



lipeds are elongated, leg-like, with an exopod; the last article is 

 long and is spinose at tip and on one side distally; preceding 

 article is much shorter. 



.Legs of first pair are short and incurved ; chela is simple and 

 not much enlarged ; legs of second pair are long and slender, with 

 small chelae; carpus 5-jointed. 



Ambulatory legs are biunguiculate, with the dactyl and propodus 

 spinulose; those of fifth pair have a large comb of numerous 

 spines on the distal part of the propodus and inner edge of the 

 dactyl. 



Uropods are large ; outer lamella larger than the inner ; outer 

 edge has short hairs proximal to the sutural spines and notch. 

 Telson is narrow, with the margins turned down and tapered to 

 a very narrow tip, occupied by six spines ; upper surface has three 

 to five pairs of spines.

This is a small, rather plump shrimp, with a short rostrum, 

 shorter than the large black eyes ; its upper margin is sloped to 

 the tip and has three to five sharp denticles. The carpus of the 

 legs of the second pair has five unequal segments. 



It is easily recognized by its peculiar antennules, the outer 

 flagellum being very thick, with a short, thin, terminal portion, 

 while the stalk is short and thick. The basal article is longer than 

 the other two combined ; it has an acute outer basal spine as long 

 as or longer than the article, and also a small distal spine on the 

 inner margin. The second article is short, wider than long, with 

 a small spine on each distal angle. 



The third article has at the distal end a small, rounded, thin, 

 flat, leaf-like appendage, with the tip acuminate. The stylocerite 

 is strong, acuminate on the inner edge, acute at tip, and reaches to 

 the end of the first article. The outer branch of the flagellum is
