and. pellucid." In point of fact the hepatic coecum is dark 

 bottle-green throughout ; the brilliant metallic blue colour of 

 the middle part of a papilla being entirely due to reflection 

 from small flecks of opaque superficial material. Above and 

 below the blue there is usually a band (often incomplete 

 posteriorly) of yellow or orange, also superficial; and near the 

 tip of the papilla the enidogenous sac shows through yellow,, 

 orange, or sometimes crimson. The general colour of the 

 sheath is pale transparent green. The extent of the blue and 

 yellow or orange colour is subject to much variation in. different 

 individuals, and in the different papillae of the same individual ; 

 often some of the opaque material appears white by reflected 

 light, especially when the back-ground of dark green afforded 

 by the hepatic cceum is lacking. Professor Herdman's descrip- 

 tion of the papillse of ^. molios is somewhat vague ; there 

 appears in his account of the species very little reason, as I 

 think, to separate it from^. cceridea. 



I have removed Ami)liorina from the sub-family TergipedinEe, 

 since, except, perhaps, for the slightly inflated character of the 

 papillag, it is, as seems to me, much more nearly akin to the 

 immediately foregoing species than to Galvina and the other 

 Tergipedinffi.

Specimens were obtained on three occasions in Valencia 

 Harbour, and were identified by Mr. Gamble. They were 

 found in weed from the shore at Eeenagiveen and di'edgednear 

 the mouth of the harbour respectively.
