32. Salmo clarkii (Richardson). Alaska Cutthroat Trout. (PI. xv, fig. 1, and pi. xxxvn.) 



In 1881 Dr. Bean recorded this trout as Salmo purpuratus from Sitka, St. Paul (Kodiak Island), 

 and " northern Alaska." Not until the investigations were made on which this report is based had ariy 

 other specimens been recorded from Alaska or any Alaskan specimens come into the hands of any ichthy- 

 ologist. Doubtless anglers and others knew of the presence in Alaska of a species of cutthroat trout. 

 Indeed, officers and members of the civilian staff of the Fisheries steamer Albatross state that they have 

 found cutthroat trout at various places in Southeast Alaska and that specimens were forwarded to the 

 Bureau. These, however, seem to have been lost en route, as they were never received at Washington. 



During the recent investigations cutthroat trout were obtained at the following places: San Mateo 

 Lake near Union Bay, Vancouver Island (June 22); lake at Courtney, Union Bay (June 22 1; Karta Bay 

 stream (July 11); Pablof Falls. Freshwater Bay (July 25); Silver Bay Creek near Sitka (July 20); Kla- 

 wak Creek (August 20), and Naha stream near Loring (August 30). Other specimens were obtained in 

 the vicinity of Loring in 1903, and again in 1904 and 1905, and numerous fine specimens were collected 

 in Lake McDonald and vicinity by Mr. J. S. Burcham in 1905. 



In all of these places the cutthroat trout was fairly common, apparently most abundant at Loring, 

 Lake McDonald, and Klawak. It doubtless occurs in many other streams and lakes in Southeast Alaska. 

 Just how far north it extends has not been definitely determined. We did not find it north of Sitka. 

 We have a photograph, taken by Mr. R. W. Stone, of the U. S. Geological Survey, and furnished by Mr. 

 Frank Hess, also of the Survey, showing a number of troul and salmon caught September 25, 1904, at 

 Kaiatla, Controller Bay, in a stream about one-fourth of a mile from the beach. Among the fish shown 

 is one that is evidently a cutthroat or a rainbow trout. 



The following notes were taken on specimens from various places: 



No. 02809, taken with fly by Dr. Evermann in Lake San Mateo, Vancouver Island, a female 

 1 1.5 inches long, weight one pound, not nearly ready to spawn. Color in life, top of head, back and side 

 to base of pectoral thickly covered with small, somewhat -lollate black spots, those on head and nape 

 roundish: check with about 7 black spots- 2 or 3 on upper part of opercle; dorsal and caudal with 

 numerous oblong black spots; 3 spots on adipose dorsal; anal with black spots less numerous than on 

 caudal and dorsal; ventrals pale rosy, the outer ray wit h a series of small black spots; pectorals pale rosy 

 on inner rays, the outer dusky; cheek and opercle with rosy; some rosy on side of lower jaw; belly 

 dusky, slightly rosy; throat with a broad, rich red dash on each side; tip of lower jaw black; side silvery 

 with bronze wash; the black spots on back and side about evenly distributed, those on caudal peduncle 

 largest. When first taken out of the water the whole fish excepl bellj appeared quite dark.
