Mediterranean ^. It is distinct from the E. jjliUocoruUia of 

 F. Buchanan. 



The fourth is Eunice philocorallia (or coralUophiln) , 

 F. Buchanan t, which was dredged in deep water off the 

 west coast of Ireland, and which ranges to Norway. In a 

 female from Norway the branchiae commenced on the 7th 

 foot and continued almost to the tip of the tail, and the 

 same arrangement was found in a male. The divisions of 

 the branchice do not exceed four^ and generally there were 

 three anteriorly. The head resembles that of Eunice pennata, 

 with a hollow on the dorsum of the palpi. Behind the 

 anterior third the spines are black. The relationship of 

 this form to the Eunice mnphilieliie of Marion and Roule + is 

 interesting, both having their parchment-like tubes on corals 

 {Ampjhihelia and Lcpliohelid) in deep water. The French form 

 is eyeless and thus differs from the British; the branchise 

 commence on the 2nd foot (fourth segment) ^ whilst in the 

 British they arise on the 7th foot^ and have never more than 

 four filaments, whereas the French has a maximum of seven 

 filaments. The dental apparatus also shows certain features 

 in common and certain differences. How far the variations 

 mentioned affect specific distinction is still a question open 

 to consideration. Some may be sexual. Roule, in a later 

 communication §, includes his Eunice ampMhelice, the E. 

 •philocorallia of F. Buchanan^ and the E. jioridana of Ehlers 

 all under the Eunice Gunneri of Storm, the two species, 

 indeed, found in the north by Levinsen || being Leodice 

 norvegica, L., and L. Gunneri, Storm. Mareuzeller^ has 

 similar views. 



The representatives of the allied genus Marphysa are 

 two in number, viz., Marphysa sanyuinea, Montagu, and 

 Marphysa Bellii, And. & Edwards. 



The former is abundant in the Channel Islands, e. g. at 

 St. Peter Port, Perelle Bay, in Herm, and in the Gouliot 

 Caves of Sark. It also occurs in the south of England, 

 e. g. Polperro. The flattened and deeply bilobed head with 

 the typical number of tentacles, the absence of the tentacular
