The Male (Fig. 7). 
Body. The cephalothorax and trunk are fused and folded together ven- 
trallv into an unsegmented ovoid without distinction of parts, so that the 
profile of the dorsum resembles that of Cypris, or has the general contour of a 
skull. The males of the genus Clavella are singularly uniform in appearance 
so that specific differences between them are not marked. The dorsum pro¬ 
trudes more posteriorly than in C. uncinata. There is neither dorsal carapace, 
nor abdominal appendages, so that the males of Clavella resemble those of 
Brachiella rather than those of Lernaeopoda, and even more particularly in

their appendages. Like Brachiella also they are of much smaller size in pro¬ 
portion to the female than in Lernaeopoda, being only just visible to the 
unaided eye. The dorsum is boldly arched, and the height is greater than 
the length. Between the maxillipedes and 2nd maxillae in the median line a 
short rounded mediative process like a carina is present, which is homologous 
with the paired structures similarly situated in Lernaeopoda. This process is 
not located so anteriorly as other authors figure it in other species, e.y. 
C. uncinata \ it is, on the contrary, in this species, in a position more in harmony 
with its above-mentioned homology. All the appendages in situ point diago¬ 
nally and forwards. The mouth cone is unusually long and the rostrum minute.
