Length, twelve to eighteen inches. 
Remarks. When my * Report on the Fishes of Massachusetts" was published, 
I had never seen a specimen of this species. In August, 1845, Captain Atwood sent 
me a specimen from Provincetown ; and in the following November I received one from 
the late Dr. Yale, from Holmes's Hole. While visiting Provincetown, in the sum- 
mer of 1847, I saw this fish swimming about in considerable numbers, in shallow 
water, with the Platessa oblonga and plana. It is not used there as an article of 
food, although Dekay informs us that in New York it-is considered a delicate fish.

Color. Upon the right side of a dark brown, marked transversely with rather in- 
distinct, irregular, interrupted black bands; the left side is of a dirty white, with 
nearly circular dark brown blotches scattered over its entire surface, and also in a 
less marked manner upon the fins. 
Description. Body oval. Length of the body, exclusive of the tail, four inches six 
lines; entire length, six inches; depth of the body two inches back of the snout,

cealed, is a strong, compressed spine, two thirds of a line in length. The mouth is 
small, with minute teeth in both jaws on the under side; on the left side the aper- 
ture is partially concealed by the upper lip. The nostrils are large. The scales on
