230 THE SCHIZOPODA. 
EUPHAUSIA Dana (1852). 
Some statements on the copulatory organs of the male first pleopods in 
this genus may be given here. The spine-shaped process is wanting (yet I 
found this process developed in the normal way in one of the specimens exam- 
ined of HZ. lucens H. J. H.); the terminal and the proximal processes are well 
developed. The median lobe is, as in Thysanopoda, separated from the inner 
lobe and has the lateral process strong and inserted at a considerable distance 
from its base, but it has generally no additional process, though this process 
is present as a small spine in #. mucronata G. O. 8. and as a mere rudiment in 
E. gibboides Ortm. The auxiliary lobe is well developed, oblong; the setiferous 
lobe is normal, with the pouch on the posterior surface very conspicuous. 
The genus comprises twenty-seven species, fourteen of which are represented 
in the material from the East Pacific. These species belong to three of the four 
groups into which I divide the genus. 
Group a. Species with two pairs of lateral denticles on the carapace. No 
dorsal process on third to fifth abdominal segment.
