This species is evidently a close ally of tbe Atlantic salmon, belonging to the 

 restricted subgenus Salmo; from Salmo solar it differs in the slightly larger mouth and 

 rather different coloration, and in very little else. 



The names Salmo mylciss Walbaum, Salmo penshinensis Pallas, and Salmo purpura- 

 tus Pallas, belong to this species. 



28. Salvelinus malma (Walbaum). Golet; " Salmon trout." (Plate XLIV.) 



Everywhere very abundant in fresh-water streams and along the beaches. Pyra- 

 mid Creek, Captains Harbor, Unalaska, Nikolski, Bering Island, Karluk, Petro- 

 paulski. 



In all these specimens the head is short (4^ to 4J in length) as compared with 

 specimens from farther south (head, 3f to 3g). TJie latter may be possibly recogni- 

 zable as a distinct subspecies, Salvelinus malma parlcei (Suckley). We have not at 

 hand, however, sufficient material to determine this point. 



The species is very common along the Aleutian Islands, as also on Bering Island, 

 where many specimens were seen. Specimens taken above the fall in Pyramid Creek, 

 a little tributary of Captains Harbor, Unalaska, are very small — not over 5 inches 

 long — and brightly colored. They are not otherwise different. 



29. Salvelinus kundscha (Pallas). Kundscha. (Plate XLV.) 



Kundscha, Krascheninnikof, Descr. Kamtch., 1745.

Salmo kundscha, Gmelin, Syst. Nat., 1788. 



Salmo Uucomaenis, Pallas, Zoogr. Rosso. Asiat., Ill, northern and eastern shores of Kamchatka.

 Salvelinu8 leiioomainis, Bean, Proc. U. S. Nat. Mus. 1896, XIX, 382. 

 Salmo curilus, Pallas, Zoogr. Rosso. Asiat., Ill, 251, 1811, Kurile Islands. 



One specimen taken by Mr. Barrett-Hamilton at Petropaulski. It has also been 

 recorded by Dr. Bean as Salmo leucomwnis, from Petropaulski, where it was taken by 

 Stejneger and Grebnitzki. This interesting species is well known in Kamchatka, 

 and its distinction from Salvelinus malma is very evident. 



One specimen, about 14 inches long, collected at Petropaulski by Barrett-Hamilton 

 agrees with Bean's description above cited, except in the longer head, which is con- 

 tained 4i times in length to base of caudal. We present a figure of this specimen. 

 . 30. Cristivomer namaycush (Walbaum). 



Recorded from the Tukon region.
