GENUS VI. ACANTHIAS, Risso. 
Two dorsal fins, with a spine before each ; first dorsal behind the line of the 
pectorals ; the second dorsal over the space between the ventral and caudal 
fins ; no anal fin. Skin rough in one direction ; the scales heart-shaped, with 
a central spine directed backwards. Temporal spiracles large. Several rows 
of teeth in both jaws, cutting and sharp, the points directed outwards and 
backwards. 
1. Acanthias Americanus, SToRER. 
All the upper part of the body is of a slate color, which is deeper upon the head and 
lighter below the lateral line ; beneath white. A row of circular white spots are situated 
just under the anterior portion of the lateral line, and a few similar spots are irregularly dis- 
tributed upon the back. The first dorsal fin commences posterior to the anterior third of the 
body; the second dorsal is nearer to the first dorsal fin than it is to the extremity of the tail. 
Upper lobe of the caudal broad, and as long again as the lower portion.
