350 Storer on the 
inside of the mouth dark colored ; gape of the mouth 
very large ; eyes circular; pupils black ; irides golden, 
with greenish reflections: distance between the eyes, 
one foot. Gill-covers, very large, perfectly smooth, 
of a silvery gray color. 
The first Dorsal fin commences two feet three in-

it is perfectly invisible. 
The second Dorsal is of a reddish brown color; 
twelve inches in height; five in length: this fin

of the Sharks, it being almost impossible to count 
the rays: nine finlets between this and the tail, of 
a bright yellow color, dark at base, and upon the 
anterior edge. 
The Pectoral fins are falciform ; of the same color |

high. 
The Ventral fins are composed of very strong rays, 
situated in a groove at their base, just beneath the pec- 
torals; above, black ; beneath, white; eleven inches 
high ; two inches long.
