SUCKLEY MONOGRAPH OF THE GENUS SALMO. 101 



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

 gals 14 to 15. Tail strongly cut out. 



Hab. — Ascends the rivers eniptyiug into Behring's Sea. A single 

 specimen of this salmon, about 32.4 iuches ia total length, was obtaijunl 

 by Sir John Richardson from the Yukou River iu Arctic America. It is 

 tliere known to the fur hunters as the retljisfi. Sir John says it is very 

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

 the Kutchin tribe tleuM-Jco. They take it by weirs constructed between 

 island aud island, and by spearing. The flesh and roe are dried for 

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

 ardson, op. cit.)

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

 ble to an exhausted or emaciated male. General form that of /S\ salar 

 when out of season, but smaller. Head disproportionately large; jaws 

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

 margin of operculum) contained four and two-third times in the total 

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

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

 premaxillary. Scales smaller than those of S. salar, but resemble them 

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

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

 outline strongly arched. Tail lunated. 



Hab. 7. — Ynkon River, Arctic America; ascends as high as the falls 

 of the Porcupine. 



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 

 aS. salar were smaller, as 12 or 13 to 10 on patches of skin of equal size; 

 140 scales on lateral Ihie. Fin membranes (juite thick. Rays Br. 12-13; 

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