FAUNA OF THE OUTER WESTERN AREA OF THE CHANNEL. 329 



with in the present report. Hincks (54) gives as localities of its 

 occurrence : Shetland, and in 40 fathoms ; Hebrides, Falmouth, Cornish 

 coast. The distribution of the species outside British waters appears 

 to be very limited : Stavanger, Norway, 50-100 fathoms (G. 0. Sars, 

 62). Hirondelle: Bay of Biscay, 131-300 m. ; Azores, 130-318 m. 

 (Pictet et Bedot, 61). Travaillcur : Bay of Biscay, 411 m. Talisman: 

 Azores, 115 m. (Billard, 48). 



Sertularia abietina, Linnaeus. 



At Positions 9, 11, 14, 35, 43, 45, 49, 53, 59, 60, 62, 67, vii, 80. 



Depth, 42-52 fath. or over. 



On dead Pecteii shells, etc. Few of the examples were in healthy 

 condition, and several were dead and overgrown. 



Sertularia argentea, Ellis and Solander. 



At Positions 3, 7, 11, 12, 44, 49, 53, 56, 60, 80. 



Depth, 40-51 fath. 



On shells of Pecten opcrcularis, P. maximus, Lutraria, Modiola, etc. 

 Mostly small or young colonies. 



Hydrallmania falcata (Linnaeus). 



This species was found generally distributed over the whole area, 

 and was recorded at nearly all positions, including 62, 64, and 80. 

 It was commonly attached to shells of Pecten, etc., and once Porella. 

 It occurred very commonly on stones dredged up nearly everywhere, 

 and in such cases often as good-sized colonies. 



Depth, 40-51 fath. 



Thuiaria articulata (Pallas). 



A fragment only was obtained at Position 13. 

 Depth, 42 fath. 



PLUMULARIIDAE. 

 Antennularia antennina (Linnaeus). 



At Positions 1, 3, 4, 6, 7-12, 14, 15, 32, 38, 40, 43, 48, 49, 56, 58, 

 62, 64, vii, 77, 80. 



Depth, 40-51 fath. or over. 



Colonies occurred growing on shells and stones at Positions 7 and 

 62, several being so attached at the latter point. Specimens bore 

 gonophores at 62 and at the doubtful position in Cruise VII. A fine 

 colony was obtained at Position 64, but the growth was not otherwise 

 remarkably luxuriant in specimens anywhere, and the quantity 

 obtained was in most cases small.
