Tribe 3. EOLIDOMORPHA. 

 Ulaaonepatica. 



Nudibranchs in which the whole of the liver is contained in the 

 integuments and the tegumentary papillae. The genital duct is 

 diaulic, and the male and female orifices are contiguous. A pair of 

 laterally placed mandibles is present. The anus is antero-lateral, 

 except in the Proctonotidce, in which it is median. The tegumentary 

 papillae are not ramified : they frequently contain terminal sacs 

 (cnidosacs), which communicate on the one hand with the digestive 

 canal, on the other hand with the exterior. The cnidosacs contain 

 nematocysts which are invaginated while they are in the cnidosacs, 

 but when expelled from them they are evaginated.
