18 STALK- AND SESSILE-EYED CRUSTACEA 
Distinguished from C. sanguineus (according to M. Edwards), only 
by the more numerous and elevated tubercles of the carapace, and the 
form of the frontal lobes, which are narrow and deeply notched, so as 
to present the appearance of two small rounded teeth. 
New Zealand (Coll. Mus. Paris). 
I have never seen specimens of this species, which, according to 
Milne Edwards’ description, is easily distinguishable by the form of the 
frontal lobes, from its congeners.
