and beset all round with dense, fine, short hairs. The 
colour is a dull white, and the valves are distinctly marked 
with three black, somewhat waved fasciae, running trans- 
versely across the shell at unequal distances, the most an- 
terior of the three being the smallest. Posterior margin 
rather narrower than anterior.*

Cypris nubilosa (?), Koch, Deutsch. Crustac., h. xii, t. 4. 
Shell of a rhomboidal form, rounded at posterior margin, 
and truncated as it were anteriorly ; glabrous, with a few 
hairs on posterior margin. The surface of the shell is re- 
ticulated, or, as Muller says, marked with small points 
impressed into, or as it were excavated out of, the shell. 
The upper part is nearly of a white colour, while the lower 
portion of anterior margin, and part of posterior, are very 
dark, shaded with a yellow green. The filaments of pos- 
terior antennae are long. 
A very pretty and well-marked species. 
* It is not so narrow at the posterior extremity as is represented by 
Jurine. Muller’s figure represents the anterior extremity as the narrower.
