JORDAN: ON THE GENUS FUSUS. 23I 



up to the date of the publication of that vol. and for nearly 

 twenty years after. Five years ago a specimen was taken off the 

 Waterford Coast, where it was trawled, and was secured by the 

 late Dr. Churchill Babington. 



The next year a perfect live specimen came from the same 

 locality and it is now in my collection. During the year 1889 

 some six or eight specimens, with the living animals, were 

 obtained from the north entrance of the Bristol Channel in 

 40 — 50 fathoms, soft muddy ground; bottom temperature 

 probably 51° to 52° Fahr. I have obtained in all four living, 

 and several dead, specimens of this rare shell, three of the 

 former are in my collection. The discovery of this new locality 

 is due to the fact that a trawling industry has lately been 

 established, having as its head-quarters Milford Haven, and the 

 shells being of large size do not readily pass through the nets. 

 One of mylive specimens was devoid of any epidermis when caught. 

 The following are additional localities : — Faroe Channel, ' cold 

 area,' 640 fathoms, bottom temperature 30° Fahr. ; ' warm area,' 

 530 fathoms, bottom temperature 46 '5° Fahr. ; on the Wyville- 

 Thomson ridge, 300 fathoms, bottom temperature 48° Fahr. ; 

 west coast of Ireland, 85 — 1230 fathoms, bottom temperatures 

 49 "6° and 3 7 '8° Fahr. respectively. 



6. — Fusus gracilis, Da Costa. 



The typical form is found sparingly off the Devon and 

 Cornwall coasts, and the species has now been found all around 

 the British Isles, also in the Bay of Biscay, ' Travailleur ' 

 expedition. 



At the Scilly Isles dead specimens have been found, but 

 they partake more of the form of var. convoluta. 



I have a live specimen, from Wick, N.B., which has no 

 epidermis, the shell has a polished surface and is semi-trans- 

 parent, this peculiarity occurs also in F. islandicus and F. pio- 

 pinquus. 



I now describe two new varieties of this common but
