the basal joint extends into an elongate and slender process 
bearing a single seta at its extremity. The secondary joints are 
very narrow and reach to about the end of the inner produced 
part of the basal joints; they are each provided with two apical 
sete—one long and one very short—and a small seta near the 
distal end of the outer margin (Pl. 3. fig. 12). 
The male differs little from the female, except in the following 
particulars :—The antennules are modified as shown in the ~ 
drawing (Pl. 3. fig. 13). The third pair of thoracic feet are 
furnished with a sigmoid appendage, which is moderately stout 
at the base, but tapers towards the extremity (fig. 14). The 
fifth pair of feet also differ slightly from those of the female. 
The Cletodes just defined is distinctly different from any 
described species with which I am familiar; its slender form, 
elongated caudal furea, and the peculiar structure of the anten- 
nules distinguish it almost at a glance from allied species. 
Only a few specimens were obtained.

Description of the female-—Body moderately stout; rostrum 
short (Pl. 2. fig. 9). Length from the extremity of the rostrum 
to the end of the caudal furca about 1 mm. 
Antennules eight-jomted, somewhat similar in structure to 
those of Dactylopus Strémii; but when compared with the 
description and figures given by Claus there appears to be a 
slight difference in the proportional lengths of the last four 
joints. Claus states that the fifth and seventh joints are short, 
and his figure shows them as being subequal; whereas in our 
specimen the fifth joint is short, the sixth and seventh subequal 
and longer than the fifth, while the last, which is longer than 
either of the three preceding joints, is about equal in length to
