PISHES "OF ARCTIC ALASKA. 497 



Hn large, inserted over the last rays of the anal; its height, 4 in head. The ventrals 

 reach more than halfway to front of anal. The height of the dorsal, IJ iu head; the 

 pectorals are slightly larger than ventrals, 1^ in head; depth of caudal peduncle, 3 J 

 in head. 



8. Oncorhynchus gorbuacha (Walbaum). 



We found this species quite abundant at Port Clarence about the middle of July, 

 at which time it was commencing to run up the river back of the inner harbor. The 

 one specimen obtained by us is 16 inches long; its dorsal, 11; anal, 14; scales, 199 

 tranverse rows or 162 in lateral line; gill rakers, 13+17; ventral appendage nearly 

 two-thirds length of fin. The natives catch this fish by means of nets about 30 feet 

 long, one edge of which they attach at the edge of the water, shoving the other end 

 out with a pole in such a position that when the salmon strike the net they follow 

 along it toward the shore. When a sufficient number has congregated at the net the 

 outer end is pulled in by means of a rope attached for the purpose. 



9. Oncorhynchus nerka (Walbaum). 



At Chignik Bay we took four of the young of this species — specimens about 3 

 inches in length. We took six of the young of this species at Grantley Harbor; they 

 are about 5 inches long. 



10. Salvelinus malma (Walbaum). 



Specimens were obtained at Port Clarence, Point Hope, and Herschel Island. The 

 natives of Herschel Island catch this fish through holes in the ice at all times during 

 the winter. 



11. Mallotus villoBus (MllUer). 



We found this fish only at Port Clarence, where it first appeared on the 24th of 

 July. On this day we observed them in great numbers in the edge of the water near 

 the sandy beach. They ran in small schools and were doubtless spawning. The 

 natives caught great quantities of them with small dip nets. We have compared our 

 specimens with others from Greenland and find no differences. 



12. Osmerus dentez Steindachner. 



We took several specimens at Port Clarence, where they were quite abundant. 

 They agree with Steindachner's description in all except the following: The head is 

 contained a little over 4 times in length of body without caudal, instead of 3f, and 

 there is no spur-like scale between the ventrals. We have compared it with speci- 

 mens from Kamchatka and can find no differences. 



13. Mesopus olidus (Pallas). 



Head, 4i; eye, 3f ; depth, 6 J. D., 9; A., 14; P., 11; V., 8; scales, 55 to 60; gill 

 rakers, 9+20, the longest two- thirds of eye; snout slightly shorter than eye; maxil- 

 lary reaching to center of pupil, or slightly less than 3 in head; least depth of caudal 

 peduncle equaling snout; the longest rays of the dorsal contained 6 or 7 times in the 

 length. The pectorals reach from fbur-flffchs to two-thirds distance to base of ventrals, 

 contained 5 or 6 in the length; the rays of the pectorals and ventrals are slightly 

 enlarged at the base. The color is dusky, silvery below; no very evident silvery band 

 along lateral line. The scales are insecurely attached and rub off easily. We found 

 this fish quite abundant in the river back of Grantley Harbor. ,
