well developed, and, as well as the three pairs of foot-jaws 
(f. 1 c, d , e), exactly resemble those of Diaptomus. 
The four anterior pairs of feet (f. 1 g) are all alike, 
and consist of a basal stalk of two articulations, and two 
branches of unequal size. The inner branch is much 
the smaller, but both are divided into two joints. The 
posterior or fifth pair is almost exactly similar to the 
corresponding pair in Diaptomus. 
I have never found this species alive, having only seen 
it preserved in spirits.
