Decapod Crustacea of Bermuda, Part II. 139 



apical spines (fig. ig). The anterior legs are usually unsym- 

 metrical. One of the first pair is chelate, the other generally not 

 so (figs, id, id'}, but exceptions often occur; those of the second 

 pair are very unequal in length, but both are chelate, long and 

 slender, the longer one about two-thirds the length of the body; 

 tips of chelae cross. The chela and carpus of the second legs fit 

 into a channel in the merus and ischium. Ambulatory legs are 

 very slender (fig. if). 



According to Miss Rathbun the American specimens have the 

 legs more slender than in the European specimens examined by 

 her. Dr. Rankin considered it distinct. The species is variable 

 in the length of the rostrum, size of eyes, antennal articles, etc., 

 and is said to have unusual ability in changing its colors. It is 

 sometimes over two inches long. 



This species was first taken in Bermuda by Mr. Goode in 1877. 

 It was also taken by Dr. Rankin, in Harrington Sound, I fathom.

My figures (plates 35 and 41) were made from a cotype, sent 

 by Dr. Rankin, of his species (P. bermudensis) , which I have here 

 treated as a variety, for lack of foreign specimens for comparison. 



The following description is from a cotype sent by Dr. Rankin : 

 Rostrum small, narrow, slender, about equal in length to eyestalks ; 

 lower margin is slightly concave, but the edges are nearly parallel, 

 minutely bifid (pi. 35, fig. i, r) ; eyes large, on short stalks. 

 Antennules stout, incurved and excavate at the base, under the 

 eyes (fig. la) ; first article longest, second 1.5 longer than the 

 third ; outer flagellum has the thick part slightly fusiform. 



Antenna (figs. la, ib) slender; carpocerite about equal to one 

 third of the first antennular article; its scale (s) is long and 

 narrow, breadth to length about 1:14; its margins beyond the 

 base are nearly parallel; tip sub-acute; it reaches beyond the 

 carpocerite and about to the middle of the third antennular article ; 

 basicerite (b) is oblong ovate and blunt.
