On tlie Occurreuce of Sepia hiseriaUs in Cornwall. 

 By Jonathan Couch, Esq., F.L.S. &c. 



[Read March 4th, 1856.J 



It appears from the " History of British MoUusca," by Professor 

 E. Forbes and Mr. Hanley (vol. iv, p. 241, and PI. P.P.P.), that 

 the Sepia bisej'ialis is regarded as of very rare occurrence in 

 Britain ; one specimen only of its shell or plate having been found 

 in England and three in Ireland. The English specimen was ob- 

 tained on the shore of the county of Northumberland. It may 

 therefore be regarded as of some importance in the completion of 

 our local fauna, to make the Liniiean Society acquainted with 

 the fact, that in the course of two days in the month of February 

 of the present year I have myself foimd no less than ten speci- 

 mens of the dorsal plate or shell of this animal, scattered among 

 perhaps a hundred of those of the Common Bone or Burn Cuttle, 

 Sepia officinalis. 



My attention was attracted to these specimens by the beautiful 

 pale pink colour of the dorsal aspect of the shell ; and a very 

 slight examination of the most perfect specimen I could find, com- 

 pared with those of the common species, was sufficient to point 

 out the decided distinction there is between them ; but as the 

 shell of this species is but little known, and those which have 

 fallen into my hands are slightly different from what is described 

 in the work above referred to, I beg leave to lay before the 

 Society a more particidar description than might otherwise be 

 necessary. 



The length of this shell, as described by Professor Forbes, was
