FISHES OF AKCTIC ALASKA. 



503 



We found this fish very abundant along tlie sliores of Herschel Island. It was 

 about the only fish to be found where the bottom was muddy. We took a few young 

 at Point Barrow, and at Port Clarence we took specimens of both the young and the 

 old. Three of the young were found in the river back of Grantley Harbor.

Two very young examples of an unknown species of Oneocotttis were taken at 

 Point Barrow. The spinous dorsal can not be made out accurately, but the number 

 is between 8 and 11, probably 10; the second dorsal has 14 rays and the anal 13. The 

 species is closely related to O. hexacornis, but comparison of specimens of the same 

 age shows numerous differences, which are indicated below. 



Young of O. liexacorvis from Point Barrow. 



OncocotUis sp. incog, from Point Barrow. 



Head compressed. 



Occipital tubercles developed. 



Interorbital space 1^ times eye. 



Caudal peduncle heavy and much compressed. 



Lower jaw projects beyond snout. 



Head much depressed. 

 Occipital tubercles not developed, 

 luterorbital space about one-half eye. 

 Cq.udal peduncle slender and rounded. 

 Lower jaw even with snout. 



23. Megalocottus laticeps (Gilbert). 



We took four specimens of this species at Port Clarence. They differ from the 

 types slightly in coloration. Our specimens are dark, almost black; below the anterior 

 portion of the second dorsal is a darker saddle-like marking on the body; the caudal 

 is black at the base, and has an undulating dark band on its i)osterior third; the i^ec- 

 torals vary, being either banded or mottled (one specimen has distinct bands on one 

 pectoral while the others are simply mottled with black). There is no slit behind last 

 gill arch.

I have compared them with specimens taken by the Albatross in southern Bering 

 Sea and find them the same. In the female taken at Port Clarence the crown (not 

 between the eyes), nape, and upper half of opercles are covered with scabrous bony
