to be four and seven tenths of the length of the body, which 
measured forty-seven inches from the snout to the border of the 
tail; from the snout to the beginning of the dorsal fin the 
same as from the ending of that fin to the border of the 
scales at the root of the tail; and from the commencement of 
the dorsal to the adipose fin the space is double that from the 
adipose fin to the border of these scales; the adipose fin is 
over the anterior edge of the anal. The operculum and sub- 
operculum taken together form a circle. Number of scales from 
the dorsal fin to the lateral line twenty-five; from thence to 
the ventrals twenty-two; and in a row between the adipose fin 
and lateral line twelve to fourteen. In the female fish the 
number of scales was less than in the male, although the body 
is higher; the head occupied five parts and one third of the 
length of the body. Artedi counted fifty-six vertebrae, but Mr. 
Yarrell more than once counted sixty. The colour of the flesh 
is found to be caused by the presence of a peculiar oil.
