The length of the specimen was eleven inches and a half, 
of which tlie body, to the origin of the caudal portion, was 
six inches and a half; the greatest breadth nine inches. The 
snout projects, slender; and, from it to the extremities of the 
pectoral fins, the border is much waved. Eyes five eighths of 
an inch asunder, and one inch and six eighths from the snout. 
Spines in front of the eyes, and in three rows along the tail, 
long, and sharp. Dorsal fins near each other, and not close 
to the end of the tail. Colour pale yellow, white below; but 
what has rendered this fish remarkable, and given it a name, 
is a very dark or black border which passes round the disk, 
both below and on the upper side, from about the middle 
of the body to the hinder part of the pectoral fins. 
I am indebted to the kindness of William Thompson, Esq., 
of Weymouth, for a specimen of this fish, which lays claim 
to the distinction of being regarded as a separate species; 
and the best account I am able to give of it, is contained in 
the letter of that gentleman, which accompanied the gift. “The 
Marginate Eay,” says he, “is rather plentiful in Portland 
Roads, on a sandy bottom, and is caught both in scans and 
trawls. It is a shallow water species, and at present I have 
never heard of one exceeding fifteen inches. The fishermen 
here will have it to be the young of some other species, but 
can give no reasons. It is, however, taken all the year round.
