. Length above 3 feet. Nose rounded; jaws equal. Teeth separate, sharp, 
hooked. Irides golden. 1st D. 10, 2d 27; P-17; V. A. f ; c. 20. The 
anal fin is small, and the tail is even. M. Cuvier states, that the air-bag is 
large, with numerous lateral processes. — A specimen of this fish, caught 
off Uyea in Northmavine, Zetland, in November 1819, and which was sent 
to Mr Neill in 1820, is the only example of its appearance on our shores. 
This specimen was 5 feet 4 inches in length : lateral line nearly straight, and 
at its termination at the tail forming a strong central scaly ray in that organ. 
Scales on the back large, 3 to 4 inches in circumference ; of an irregular 
trapezoidal form, set on obliquely to the axis of the body. It was first ob- 
served by the fishermen endeavouring to escape from a seal. When taken 
into the boat, it made its usual purring sort of noise. Mr Neill has record- 
ed, (Edin. New Phil. Journ. No. I.) some notices respecting the capture, and 
the appearances exhibited by the specimen, which came into his possession in 
too mutilated a state to permit him to give its characters in detail. It ia 
common in the Mediterranean. Is this the fish referred to by Mr Couch as 
the Stone Basse, which approaches the shores of Cornwall, following pieces of 
wood covered with Bernacles ? — Linn. Trans, xiv. 81.
