140 Bev. Canon Norman's Revision 



dredged two dead examples 40 to 50 miles off the south- 

 eastern coast of Shetlaiid in 78 fathoms. Jeffreys had the 

 more important MoUusca in these expeditions, while I had 

 the animals of other classes, and these two specimens are now 

 in the United States National Museum. It has not been 

 again met with in our seas until the last few years, when 

 specimens have been obtained from fishermen's lines from the 

 west of Dunmore, Co. Waterford. Two of these I procured 

 through Mr. C. Jeffreys, of Tenby. They are living and 

 very fine shells, 4| inches long. One when sent off to me 

 was still alive, and when it arrived, though dead, the animal 

 was quite sweet and fresh. ' Porcupine,' 1869, between 

 Galway and the ' Porcupine ' Bank. Sipho islandicus was 

 dredged by the * Voringen ' as far north as midway between 

 Beeren Island and Spetsbergen in 123 fath. Its most 

 southern known locality is coast of Marocco, * Talisman ' 

 {Locard). 



2. Sipho gracilis (Da Costa). 



This species is subject to very considerable variation. 

 Mr. H. Jordan has described ('Journal of Conchology,' vol. vi. 

 1890, p. 232) three British forms under the names var. BeJli- 

 ana, var. Coulsoni, and var. convoluta, the first from the 

 coasts of Wexford and Waterford, the second from Shetland 

 (where it is the common form on the " Haaf "), the last from 

 Wick, N.B. ; but these varieties can scarcely be recognized 

 by descri]jtions. Var. co7ivoluta has been sent to me by 

 Mr. Jordan from another locality, the Scilly Islands, and I 

 have fine examples of it from the Dogger Bank. The Sipho 

 glaher of Verkruzen and Sars (/. c. p, 271, pi. xv. fig. 7) is 

 also nothing more than a short variety of S. gracilis in which 

 also the spiral sculpture is almost obsolete. The range of the 

 species southwards extends to Marocco, where it was dredged 

 by the ' Talisman ' {Locard).
