marine productions, they have been known to feed 

 on shell-fish, although they are furnished with no 

 apparatus whatever in their mouth for reducing them 

 to a state calculated for digestion. Some that were 

 purchased by Mr. Collinson had their bellies hard 

 and prominent, appearing to be filled with rows of 

 some hard substance, which, on being opened, 

 were found to be shell-fish. These, from the bulg- 

 ing of the shells and the intervening interstices, 

 gave the intestines somewhat the appearance of 

 strings of beads. On further examination, some of 

 them were found nearly dissolved, others partly so, 

 but many of them whole*. The most usual food 

 of the Soles is the spawn and young of other fish. 



Soles are found on all the British coasts: but 

 those of the western shores are much superior in 

 size to what are taken in the north, since they are 

 sometimes found of the weight of six or seven 

 pounds. The principal fishery for them is in Tor- 

 bay.

• IN this tribe, although the species are very nu- 

 merous, there is only one of which I have met 

 with any account in the least degree interesting. 

 The head and mouth of the Chastodons are small,
