DeEscriPTion.—An apparently new species near bouvierti Milne Edwards! 
(=edwardsii Dana?), leviusculus Dana? (de Man) and bastardi Coutiére.® At first 
glance it appears to be the bouvieri of Milne Edwards, but it is readily distinguished 
by the relation of the spine to the blade of the antennal scale. In C. bowers the spine 
exceeds the narrow scale-by about one-fourth its length (de Man, loc. cit., p. 412), 
as it does also in C. leviusculus. From C. bastard our species differs in having longer 
antennal scales, shorter antennal peduncles, and more distinctly carinated rostrum. 
The rostral projection is acute, and apparently more sharply carinated than in 
any of the related species; the rostral carina is continued backward on the carapace 
to the level of the bases of the cornes; on either side it is separated from the orbital 
hoods by a shallow depression; anteriorly the rostrum extends forward nearly one-
