FAUNA OF THE OUTER WESTERN AREA OF THE CHANNEL. 363 



Membranipora lineata (Linnaeus.) 

 At Position 51 (H). 

 Depth, 43 fath. 



MICEOPORIDAE. 



Micropora coriacea (Esper). 

 At Positions 8, 43, 56, 60, 80 (H). 

 Depth, 43-51 fath. 



CELLARIIDAE. 

 Cellaria fistulosa (Linnaeus). 



At Positions 1, 3, 4, 8, 10, 11, 13, 14, 32, 33, 34, 35, 40, 49, 51, 56, 



58, 59, 60, 62, 64, vii, 80 (C). 

 Depth, 40-51 fath. 



This, the most common species of Cellaria obtained, seldom occurred 

 in any considerable quantity except at the first three positions above 

 named where, on the fine sandy ground, it was fairly plentiful. 



Cellaria salicornioides, Laraouroux. 



At Positions 3, 4, 8, 10, 11, 13, 14, 33, 47, 49, 56, 59, 60, 62, vii, 80 (C). 



Depth, 40-51 fath. or over. 



This species occurred far less frequently than the preceding, but the 

 same general statement applies to it. 



Cellaria sinuosa (Hassall). 



At Positions 40, 45, 47, 56, 58, 60, 62, 80 (H) ; 13, vii (C). 



Depth, 42-51 fath. or over. 



The comparative scarcity of this species, which is common on the 

 Eddystone Grounds, is remarkable. It is possible, however, that it was 

 overlooked at some of the innermost positions. 



CEIBEILINIDAE. 

 Cribrilina figularis (Johnston). 

 At Position 59 (H). 

 Depth, 49 fath. 



Cribrilina radiata (Moll). 



At Positions 8, 11, 12, 38,44, 45, 49, 56, 59, 60, 80 (H).
