Report on the Marine Fauna of S. W. of Ireland. 623 



Mollusca. 



During the cruise the larger shells brought up were carefully 

 collected; the results were, however, disappointing, considering the 

 number of hauls taken by both dredges and trawls. This was, perhaps, 

 due to the nature of the bottom examined being principally sand or 

 mud, or, as frequently happened, rocky, in which latter case the 

 dredges fouled badly and came up empty. The sand and mud brought 

 home for microscopic examination proved to be rich in the smaller 

 forms, and advantage was taken of the necessary washing and sifting 

 of this material to secure them. Mr. Joseph "Wright — on whom this 

 great labour falls — handed over to me the result of these washings, 

 twenty-one packets of the coarse material. The material from Sta- 

 tion V. — the deepest water dredged on the cruise — has yielded a num- 

 ber of very minute shells, which have been forwarded to Rev. A. M. 

 Norman, M.A,, who has kindly consented to verify them. 



A tabulated list is appended, representing in all 133 species, a 

 smaller number than might have been expected. In addition, there still 

 remains some material from several of the stations not yet fully exa- 

 mined ; also several critical species which remain for more satisfactory 

 identification.
