muciferous epidermis, aud do not even toiicli each other. Branchioste- 

 gals 14 to 15. Tail strongly cut out. 



Hab. — A.scends the rivers einptyiiig into Behriug's Sea. A single 

 specimen of this salmon, aboirt 32.1 inches in total length, was obtained 

 by Sir Johii Richardson from the Ynkou River in Arctic America. It is 

 there knovvn to the far hunters as the reljiih. Sir John says it is very 

 distinct from any of the European anadromous salmon. It is called by 

 the Kutchin tribe tleaJch-Jci>. They take it l)y weirs constructed between 

 island and island, and by si)earing. Tiie llesh and roe are dried for 

 winter use, and the tough skins are made into clothing. (Vide Rich-

Sp. Ch. — Drawn from Richardson's description and probably applica- 

 ble to an exhausted or emaciated male. General form that of IS. sahir 

 wh(m out of season, but smaller. Head disproportionately large; jaws 

 distorted. Length of head (when measured from tip of snout to distal 

 margin of oi)erculum) contained four aud two-third times in the total 

 length of the fish. Cartilaginous snout decurved and extending con- 

 siderably beyond the mandibles. Five or six rather large teeth on each 

 premaxillary. Scales snmller than those of /S^. salar, but resendile them 

 in delicacy of luster, and the ease with which they can be detached. 

 Tongue armed with two parallel rows of teeth, six on each side. Dorsal 

 outline strongly arched. Tail lunated. 



Hae. 7. — Yukon River, Arctic America; ascends as high as the falls 

 of the Porcuj)ine. 



Sir John Richardson drew his description from a male about 23.5 

 inches in total length. In this the scales in size compared to those of 

 *S'. salm' were smaller, as 12 or 13 to 10 on patches of skin of equal size; 

 140 scales on lateral line. Fin membranes quite thick. Rays Br. 12-13; 

 D. 11-0: A. 15; C. IJ^-: P- 1^ or 15: V. 9-9, or 10-10.
