TOKBAY BONNET. 149 



picked up in so fresh a condition as this ; but, of course, 

 it is more valuable when it occurs in a living state. 

 But this scarcely ever happens except by dredging, or 

 by trawling. I have frequently had it brought to me 

 by trawlers both at Weymouth and Tenby, oftenest by 

 the former, who get it in deep water, from thirty to 

 fifty fathoms, on the western side of Portland. 



The living animal is not unworthy of its elegantly 

 painted house. Its colour is usually pale yellow, with 

 a rose-pink mantle, bordered by a fine orange- coloured 

 fringe. The head is large and swollen, furnished with 

 tentacles, which carry the eyes at their bases. The 

 tongue -ribbon carries seven rows of teeth, of which the 

 central one differs in shape from the rest. 



I have kept a specimen in the aquarium for a con- 

 siderable time, with very little addition to my know- 

 ledge as the result. It remained adhering to the scallop 

 shell on which it was found almost all the time I had 

 it, occasionally shifting a hair's-breadth to the one side 

 or the other. Almost always the fringed edge of the 

 shell was so closely applied to the support as abso- 

 lutely to forbid intrusion ; but now and then a very 

 slight lifting of the edge all round gave me the narrow- 

 est possible peep at the broad cream-coloured foot ad- . 

 hering to its rest. Thus it went on tantalizing me, till 

 after some months I lost it, I forget how.
