 as food, either fresh or salted, this is thought wor- 

 thy only to bait the crab-pot, or, just as frequently, 

 to be thrown aside for manure. It is of frequent 

 occurrence in moderately deep water, from spring to

 as in other parts of the north of Ireland.

 Mr. Yarrell notices this fish under the name of P.

 is almost impossible to determine with certain tv. It 

 was described by Montagu in the second volume of 

 the "Wernerian Memoirs, as the Shagreen Ray, a 

 name since adopted by most authors. The snout is

 of the Dog fish ; tail with only two rows of spines, 

 there being none on the central ridge ; colour beneath 

 white. It has been taken on the Devonshire coast, 

 at Scarborough (where it is called the French Ray), 

 and on several of the Irish coasts. It appears to be 

 nowhere so plentiful as in the Firth of Forth, where, 

 as we are informed by Dr. Parnell, it is occasionally
