-ADDITIONS TO THE FAUNA OF CORNWALL, 155 



I have also obtained two species of Shells which hitherto have 

 not found a place in our Fauna. They are : Trochus grcmulatus 

 (two examples), and Pilicl'mm fulvum, which was attached to a 

 dead shell of Pinna ingens ; it is, probably, not rare, but, being of 

 small size, it is generally overlooked. 



But the most interesting addition to our own and the British 

 catalogues is a Fish, of which there is not another known example 

 in England, nor, I believe, in Paris ; and which is regarded by 

 Naturalists as being everywhere of the highest degree of rarity ; 

 it having been seen only in Madeira and the Mediterranean Sea, 

 and that only in very few instances. It was thrown on shore 

 alive, in a boisterous east wind, on a beach in the neighbourhood 

 of Dodman Point, and at first was in danger of being consigned, 

 as a sturgeon had formerly been near the same place, to the crab- 

 pot as bait ; but from this fate it was rescued by the interference 

 of Mr. Matthias Dunn, of Mevagissey, who bought it for my in- 

 spection. It was in vain that I sought either its figaire, or a 

 description of its remarkable characteristics, in the ordinary Works 

 on Natural History ; but I have found it described, in a manner 

 not to be mistaken, under the navae Ausonia Cuvieri, in the 2nd 

 Volume of Dr. Gunther's Catalogue of Fishes, published by the 

 Trustees of the British Museum. That description was contributed 

 by the Reverend Mr. Lowe, who had seen it at Madeira ; although 

 it is not comprised in that gentleman's work on the Fishes of that 

 Island. Mr. Lowe's account is in some particulars defective, and 

 in others scarcely accurate; and therefore it is with much satisfac-* 

 tion that I have been ahle to obtain a correct coloured likeness of 



Ausonia Cuvieri.

 brilliant, under the sun's beams, as, according to Mr. Dunn's
