will take pieces of the flesh when given as food, but other 

 fish refuse it altogether. Crabs will take it as food only 

 reluctantly, although they will readily eat weak or dead 

 Sepia. 



Cephalopoda have been recorded as follows from the 

 stomachs of British fishes: — 



Loligo, in Cod, Whiting, Gurnard, Plaice, Skate. 



Octopus, in Iladdoclc, Ling, Whiting-, Plaice. 



Eledone, in Ling and Angler. (Two isolated cases 

 only.) 



Rossia, in Haddock, Whiting, Cod, Gurnard, Dab, 

 and Long Hough Dab. 



fiepiola, in Whiting, Cod, Gurnard, Tope, Thorn- 

 back, Dab, and Pout. 



EXTEKNAL FEATURES. 



I. — Skin. 



The skin of Eledone has a smooth external surface. 

 It is soft and slimy to the touch, and contains numerous 

 gland cells. These secrete an opaline mucus, which is 

 especially noticed while killing the animal, say, with 

 chloroform, when the body becomes coated with this 

 secretion. It is, however, by no means as thick or sticky 

 or as abundant as that secreted by Archidoris, or the 

 common garden slugs, under similar conditions. In 

 appearance the skin is smooth and velvety, and reminds 

 one of a peach. It is also tough and elastic. When 

 Eledone is quiet it may be noticed that the skin is finely 

 granulated all over the body. In addition to these 

 granulations, there are also larger conical processes or 

 cirri, on the head and bade, of 6 to 12 mm. in height.
