est width same as greatest depth and about equal to one fifth 
the length of fish. 
'The first dorsal fin arises on a line just posterior to ex- 
tremityof thesuperior opercular spine ; sub-triangular ; some- 
what rounded above and posteriorly ; its height about half its 
length. 'The anterior spine, which is stoutest, projects least 
beyond the connecting membrane. 
The second dorsal, which arises abruptly almost at the very 
termination of the first, is quadrangular ; its height about one 
third its length. 
Pectorals large, semi-triangular; their length two thirds 
their greatest height; superior rays nearly six times as long 
as inferior. They arise beneath the humeral spine, posterior 
to origin of first dorsal, and their base follows the curve of the 
branchial aperture nearly to abdomen. They extend, as do 
the ventrals, to beyond the commencement of the anal. 
The ventrals, whose length is one fourth that of the fish, 
arise on a line half way between the humeral spine and origin 
of first dorsal, just below the termination of anterior third of 
base of pectorals. Tips of rays project beyond connecting 
membrane. 
The anal commences on a line anterior to origin of second 
dorsal, and extends to just posterior to the termination of that 
fin. Its rays like those of the dorsals and pectorals are some- 
what free at extremities, 
The caudal is rounded posteriorly.

In the preopercular spines this species somewhat resembles 
the A. pistilliger of the north-west coast, from which, how- 
ever, it differs in all other respects. It seems not an un- 
common species on the Labrador coast, inhabiting chiefly 
the Straits of Belle Isle, in which it takes the place, as it were, 
of the Grenlandicus. Caught in from ten to twenty fathoms
