THE FISHES OF ALASKA. - 259 



Another specimen (no. 02810) from the same place, an immature male 9.5 inches long, was similar 

 in life color to tlii- on.- above described, except that there were no spots on ventrals, and cheeks and 

 opercles were more spotted, there being 3 or t spots on preopercle and tie- same number on opercle. 



An example (no. 02811 1, 11 inches Ion.', from Courtney Lake, was a male somewhat more mature 

 than no. 02810, and its color was similar, except thai tie- spots "it side of head were less numerous, 

 being but 4 on upper part of cheek, 2 on preopercle and 1 on upper part of opercle. < In no. 02810 the 

 spots extended farther down; Bcales about L65. 



Another example (no. 02812), 6 inches long, from sane- place, is profusely spotted like the oilers 

 and shows traces of parr marks. The red on throat present, but not distinct. 



A fine L3-inch example, taken July 11 by Lieutenant Mitchell in Carta Hay Stream a short distance 

 above the mouth, when fresh was dark olive on back, side silvery, belly white; back and upper four- 

 fifths of side profusely covered with small irregular Mark spots: side of bead with a few small round 

 black spots: cheek and middle of siilo with pah- rosy wash: throat with light red wash, fins all dark; 

 dorsal and caudal with many large black spots; anal a little paler and with fewer spots; ventrals still 

 paler, black inside; pectoral dark, with 2 or :', small black spots. Dorsal Hi: anal 12. 



A 9. 5-inch specimen (no. 02944), weighing 1 ounces, caught by Dr. Evermann at Pablof ['alls. 

 July 2o, was in life yellowish green on l>aok and upper part »i side; middle of side slightly rosy, belly 

 silvery: hack with close-set small roundish black Bpots; side with larger black spots: top of head and 

 cheek with -mall round black spots; opercle somewhat rosy: throat rich red. 



Another was silvery, dark, profusely spotted with black, and with tie- red on throat very distinct. 



No. 03021, taken at Klawak, August 26, had lie- body and head profusely and uniformly covered 

 with large, irregular black spots; tins all denser} spotted. 



Two 7.5-inch specimens (2 and 2.5 ounces each . taken by Lieutenant Mitchell and Chief Engineer 

 (rater at Silver Bay tear Sitka, had t In • .-pots con lined chiefly to hack and side above lateral line and 

 head: caudal peduncle with more spots; very little red showing on throat of second, none on tirst: 

 side somewhat rosy, cheek also. It maj be thai these are young steelheads. 



We have critically examined more than 30 excellent examples of cutthroat trout from the vicinity 

 of Yes liny and Luring, and many other specimens from those places, Klawak. and elsewhere, in 

 Southeast Alaska, have passed through our hand-. An example 14.5 inch,- long from Lake McDonald 

 may be regarded as typical: Head 4.4; depth 4.4: eye in head (5.5; snout 3.5; maxillary 1.9, reaching 

 slightly past orbit; pectoral 1.8; least depth of caudal peduncle 2.4; scales about 146. Bod] robust, 

 not greatly compressed, the' caudal peduncle stout; head rather long and conic; snout rather long 

 and pointed. Entire body covered somewhat profusel) with small stellate I, lack spots, less numerous 

 On lead, where they are more nearly round. Dorsal, anal, and caudal I ins profusely spotted ; pectoral 



with a few spots, ventrals plain; ventrals and anal slightly tipped with yellow; a bright red dash 

 on the throat. 



The Alaska cutthroat is close to the' Alaska rainbow and may not be always readily distinguished 

 from it. We believe them to be distinct species, however. The cutthroat maj be distinguished !>y 

 its red throat, more stellate black spots, longer head, longer maxillary, li ss brightly tipped ventral and 

 anal tins, and smaller scales. The number of scales in the lateral line runs from 111) to 180, while in the 

 rainbow it runs from 120 to 1 10. The cutthroat is not a- large as the rainbow, the largest example , i 

 by us being only 14.5 inches long. The numerous examples examined range in length from 6 to 1 1.5 

 inches. At Klawak local anglers stated that the cutthroal does not attain as large size as the rainbow 

 of the same stream, and this statement was borne ou1 byourown observations at that place; also at 

 Loring and Lake McDonald. 



The Alaska cutthroat trout ranks high as a game fish, though nol equaling the rainbow . It i- a much 

 better game fish than the Dolly Varden or salmon trout. It strikes with more vim, lights more viciously, 

 dives more deeply, ranges more widely, and i- much more apt to jump; but when once out of the water 

 it is more quiet than the Dolly Varden. It take- the tl\ readily, but of course the baited hook is more 

 attractive. 



Mr. A. IL Alexander and the senior « titer of this report visited San Mateo Lake June 22 expressly to 

 obtain examples of this trout. At tirst we rowed about over the lake sometime, trying different appar- 

 ently likely places with different kinds of flies and. finally, other lures. One slight strike was gotten 

 in the upper end of the lake, but noothers until we reached a small cove on the south side, where
