182 APPENDIX. 
Habitat.—One specimen only takén off Sunderland 
in the surface-net. 
My knowledge of this species is confined to the 
single specimen from which it was originally described. 
Seeing, however, that no true marine Cyclops is 
known (the species described as such being insuffi- 
ciently examined as to structure of mouth-organs, 
&c.), 16 seems more probable that C. ovalis will be 
found to belong either to the genus Cyclopina or to 
Cyclopicera. 
Fig. 1 in the woodcut represents the anterior 
antenna; fig. 2, the posterior abdominal segments 
and tail.
