" THETIS " SCIENTIFIC RESULTS. 



the third and fourth joints are subequal, the last is short and 

 about equal to the width of the first. 



The first and second pairs of legs are subequal, the following 

 pairs are rather stouter and longer. The fourth, fifth, and sixth 

 joints are armed inferiorly with spines, which are more or less 

 pectinated ; the spines of the first and last pairs being the most 

 distinct. The superior distal borders of the fourth joints are 

 each fui'nished with similar spines ; the same remark also applies 

 to the fifth joint in all, except that of the first. The seventh 

 joint is stout, curved, and very unequally didactyle. 



Inner ramus of the first pair of pleopods elongate and sub- 

 triangular, outer ramus oblong. The inner ramus of the second 



pair is rather broader, 

 and the outer narrower, 

 than those of the 

 first. The stylet is 

 cylindrical, the apical fifth 

 much attenuated, and 

 bears numerous setse along 

 its distal margins. Outer 

 rami of the following three 

 pairs with sutural lines, 

 the last exhibits five lobes, 

 covered with rasp-like 

 teeth; there are two near 

 the apex, one in the middle 

 of the border above the 

 sutural line, and two im- 

 mediately below it. Uro- 

 pods subequal, the basal 

 joint oblong and truncated 

 at the extremity, the 

 second joint is ovate, with 

 a single small denticle on 

 its outer distal margin.
