MARGUERITE HENRY. 



posed of about twenty-five segments, some of the proximal' 

 ones being very small. The oral parts are similar to those 

 of the preceding species. 



The first four pairs of legs have both rami composed of 

 three segments. The spines on the terminal segments of 

 the outer rami are long and coarsely denticulated. The 

 fourth pair of legs bears a curved denticulated spine on the 

 inner edge of the basal segment as well as the usual bristle. 

 The fifth pair of legs is armed as in the preceding species; 

 the curved process of the middle segment of the outer 

 ramus is large and coarsely denticulated. The inner ramus 

 reaches beyond the middle segment of the outer. The 

 rounded ovisac is situated on the ventral surface. 



The male is slightly smaller than the female and has a 

 slender abdomen composed of five segments. 



The right antennule bears three or four sensory processes 

 and several short spiny projections; it is more swollen 

 than that of the preceding species. 



The fifth pair of legs are short and very stout. The 

 right leg (fig. 11) is longer, and bears a curved spine on the 

 terminal segment of the outer ramus, the two other seg- 

 ments each bear a spine on the outer edge ; the inner 

 ramus consists of two segments, the terminal one bears a 

 spine. The outer ramus of the left leg (fig. 12) is composed 

 of two large segments; the broad expanded terminal one 

 bears four short spines and a longer denticulated spine on 

 the outer edge; the second segment bears a denticulated 

 spine; the inner ramus consists of a single segment bearing 

 four short spines. 



This species is smaller than the preceding one; the mam. 

 points of difference are as follows. The antennules, although 

 consisting of the same number of segments are compara- 

 tively shorter; the right one in the male is more swollen.
