Hippouacea, Cams, Handb. der Zoologie. 



The animals belonging to this family are distinguished from 

 the AmphinomidsB by being destitute of a caruncle or crest on 

 the buccal or cephalic segment, and by having their feet dis- 

 posed in only one row. Branchiae are present on the dorsal 

 segments of the body, and are disposed either in tufts, rows, 

 or groups. Some of the genera {Hipponoe) possess tentacles, an- 

 tennae, and palpi ; others (^Lophonota, Didymobranchus) are des- 

 titute of these appendages. The eyes are four {Hipponoe, Lo- 

 phonotus), placed near each other, small.
