of it in the Wernerian Memoirs, as quoted. More than 

 twenty specimens have within a few years been taken at dif- 

 ferent parts of the coast of England, Wales, and Ireland. 

 By the kindness of Mr. Couch, I possess three examples that 

 were taken in Cornwall ; and from Mr. William Thompson, 

 of Belfast, we learn that five or six specimens have been ob-

There is also an interesting account of this fish, with a good

I carefully dissected off the whole of one side from one of 

 the three specimens sent me by Mr. Couch, laying bare the 

 vertebral column and the intestinal canal. The bones form- 

 ing the vertebrae have no spinous processes whatever, either 

 superior or inferior ; the angles of the ascending and de- 

 scending oblique indented striae, visible on the external sur- 

 face of the skin, mark the points of union of the different 

 vertebrae ; the oblique muscles between the striae are attached 

 to the bodies of the bones forming the column ; the margin 

 all round each vertebral bone is opaque, but the centre or 

 body of each is transparent. 



The intestine is a single straight canal of small calibre, 

 reaching from the head to the vent ; after passing from the
