 membranous portion is two inches and one- 

 fourth in length, rounded, two inches and one- 

 fourth in height of the central rays. 



The anal tin, coterminal with the dorsal, is 

 two and three-fourths inches in length, two and 

 a half inches in height. 



The pectorals are nine-tenths of an inch in 

 length, two inches and three fourths in height. 



The ventrals a little posterior to the pectorals 

 are four-tenths of an inch in length, two inches 

 and one-fourth in height.

The cirrhi of the head are a siugle pair ; one

'Vhv first dorsal is one inch and a-half in length. 

 seven-tenths of an inch in its greatest height. 

 From the first ray there is a gradual shortening 

 to tin 1 fourth : the fifth is then nearly as high as 

 the first, and thence the fin decreases to its ter- 

 mination-thus showing a partial division, though 

 this division is less than in the Acadianus. The 

 dorsal may almost be deemed a continua- 

 if the first. It is two inches in length, 

 eight-tenths of an inch in height, becoming low- 

 er posteriorly. The first dorsal arises half an 

 inch to the angle of operculum. 



The m, id terminates half an inch from the cau- 

 dal, its last ray being on 1 he same plane with

The pectorals, of the cottoid form, are three-

The ventrals, half an inch posterior to the

The caudal, nearly square, is an inch in height. 



In color, this fish commonly shows a mottling
