with, the movable ramus slender, bifurcate, the outer branch 

 short, tooth-like, the inner longer, slightly curved outwards, sub- 

 acute ; immobile ramus a little longer than the mobile ramus, 

 broad at base, but tapering to the apex which is curved outwards 

 and acute. Length £ in.

A near ally of the preceding species. Specimens from the same 

 localities which are probably the females of this species (Plate 

 III., fig. 2.) or of C. hjstrix are distinguished by having all the 

 spines of the body replaced by tubercles, by wanting the posterior 

 process of the first abdominal segment, and by having the rami 

 of the uropoda smaller. 



Cilicaea curtispina, sp. nov., Plate III., fig. 4. 



Surface smooth. Head large, strongly arched, First and 



fourth segments of the thorax much broader than the others ; 



epimera very distinct — their outer borders carinated. First 



segment of the abdomen finely granular, marked laterally with 



three depressed divisional lines, with two teeth on either side on 



its posterior border ; posterior process short, blunt, rounded. 



Terminal segment having the lateral elevations pointed ; terminal 



notch concealed from above by a prominent trilobed process the 



middle lobe of which is the largest. Internal antennae separated 



by a tolerably large lobe ; basal segment of the peduncle very 



large, more than half the length of the head, not much dilated, 



armed distally and internally with a blunt tooth ; second segment 



scarcely half the length of the first, armed terminally with three 



small teeth ; third segment very small ; flagellum much shorter 



than peduncle. Outer antennse more than a-third of the length 



of the body ; last segment of the peduncle the largest ; flagellum 



longer than peduncle. Mobile ramus of uropoda stout, truncate, 



armed with two acute teeth at its extremity and one about the 



middle of its outer border. Inner ramus very short, closely
