Fam. Goniodorididae. 



In this family, contrary to the preceding one, the rhino- 

 phores are not retractile, the radula is reduced (narrow) and the 

 velum is replaced by side lobes of the head.

Lophodoris G. O. Sars 1878. 



In G. O. Sars' excellent work of 1878\ we meet with this 

 genus as a nomen nudum, applied to the species danielsseni 

 of Friele & Hansen mentioned on p. 364 (in the table) and p. 

 459 in the explanation of Tab. XfV fig. 7, representing the 

 radula of this species; on this page a note informs us that it 

 is a new genus. As nothing afterwards has been published about 

 it, and as no diagnose has hitherto appeared, I find it convenient 

 to give one here, based on the material at my disposal. Accor- 

 ding to the specimens before me the generic characters are the 

 following: Notum wide, covering the head and the sides of the 

 body, but leaving the end of the foot uncovered. Margin of
