380 MARSHALL : ADDITIONS TO ' BRITISH CONCHOLOGY.' 



fathoms; west coast of Ireland, 251 fathoms; and Loch 

 Torridon, z<o fathoms (' Porcupine' cruise). 



Neaera rostrata Spengler. Tliis was described and figured 

 by Jeffreys in their proper places in ' British Conchology,' 

 but omitted from Mr. Somerville's list, as it was introduced 

 into the British fauna on the very slightest grounds — 'a 

 right valve only.' But Dr. Jeffreys afterwards' dredged it 

 off the west of Ireland and off the Butt of Lewis, and it 

 may be well to retain it, at least tentatively, as a British 

 species. 



Cassidaria echinophora L. (See 'J. of C for October, 

 1893.) The specimen in the British Museum was inad- 

 vertently labelled C. echi)iophora^ but has now been 

 corrected to C. iyrrhena Lam., and the date of its discovery 

 should be 1890, and not 1886, as stated in my paper. 

 Specimens of C. iyrrhena were, however, taken in 1886, 

 as well as on several other occasions, off the coast of 

 Ireland, and Professor Haddon has given the following 

 records in the Proceedings of the Royal Irish Association 

 (I., pp. 40 — 42) : — (i) Off Valentia Island, Kerry, 40 

 fathoms, a dead specimen taken in the trawl, 1880; 

 (2) off the south-west of Ireland, 265 fathoms, two live 

 specimens dredged in a cruise organised by the Royal Irish 

 Academy, 1886. I am indebted to Mr. A. R. Nichols, of 

 Dublin, for the following further records : — (3) Off the 

 south-west of Ireland, 345 fathoms, a live specimen pro- 

 cured in another cruise of the Royal Irish Academy in 

 J 888; (4) off the same part of the coast, 400 fathoms, two 

 specimens dredged by H.M.S. 'Research,' in 1889. In 

 addition to the above, fragments were dredged in the 

 'Porcupine' cruise of 1870 off Ireland, in 539 fathoms, 

 in lat. 48^ 6' N., long. 9^ 18' W. 



The particular specimen in the British Museum was 

 taken with another in a fishing expedition organised by 



J.C., vii., Apr. 1894.
