This can be easily distinguished from the other allied small 

 shrimps of this region by the rostrum, which is rather slender, 

 acute, nearly straight, with about eight to ten teeth above and 

 two to four below, at its wider distal portion. 



The telson is also characteristic. It is long-ovate, tapered to 

 the narrow tip, which is armed with six unequal spines and has an 

 acute median apex. The legs of the second pair are about as long 

 as the body. The following description was made from females 

 carrying eggs, taken April 19, 1898, at Long Bird Island, 

 Bermuda. 



Body gibbous, about 22 mm long, rather stout. Rostrum 

 lanceolate, laterally carinate, as long as the antennular peduncle. 

 It begins well back of the eyes at a dorsal tooth, well separated 

 from the next ; three teeth are behind the eyes ; altogether there 

 are 8 to 10 dorsal teeth ; inferior teeth are smaller, usually three, 

 often two, on the widest part. The end of the rostrum is thin, 

 flat, moderately wide; tip very acute, a little turned up. 



The antennal scale is large, wide, obtuse, more than twice as 

 long as the stalk and longer than the antennular stalk ; its distal 

 spine is a little longer than the scale ; it reaches about to the end 

 of the antennular stalk (figs. 2b, 2b'), which is wide and excavated 

 at the basal segment. Basal segment is about equal in length to 

 the second and third combined ; it has a small, wide, inner spine, 

 and a large outer scale, reaching to the second segment and having 

 a sharp spine on its outer distal angle, with a row of stiff plumose 

 hairs on its end. The second segment has a narrow thin border 

 fringed with hairs (pi. 45, figs, i, la, 2a). The outer flagellum is 

 thickened and at the ninth or tenth joint gives off a slender branch ; 

 the part beyond the branching tapers to a slender tip. The stato- 

 cyst contains a roundish concretion made up of concentric layers. 



The third maxilliped is very hairy and obscurely 5-jointed. Its 

 third article is strongly incurved, enlarged distally, and bordered 

 by small spinules and longer hairs (figs. 2n'", nn'"). The fourth 

 joint is about equal in length to the third, straight, and covered 

 with long hairs, with a large distal cluster on the inner angle. 

 The last article is somewhat shorter than the preceding and tapers 

 to a narrow tip ; it has about seven transverse rows of hairs and 

 a longer terminal cluster, without spines.
