l.road cadiiiiuiii or deep oranoc-n.,! hand from throat to anal tin. the- color deepest 

 Ix'twecn pi'ctoial and vcnti-al: sonic red on belly between orijj-in of anal and hasc of 

 (■au<lal: about \o roundish or vrrticaily o'olono- parr-inarks on iiikldle of side. uji<:n 

 which apparently the rosy lateral band is superimposed; 3 of these parr-marks are 

 oil the caudal pedunele posterior to the adipose tin, '2 between the adipose and dorsal 

 fins, -2 under the dorsal, and 3 anterior to it; between the tirst and second larg-e parr- 

 murks and somewhat below them is a small round spot of the same color, and there 

 is a similar one between the fifth and sixth spots; cheek and opercles bright rosy, 

 edged posteriorly and below with yellowish, an olivaceous blotch on upper part of 

 cheek and a small black spot on upper part of opercle; region about eye olivaceous 

 yellow, esjjecially bcdow; lowt>r jaw rosy, with some yellowish, membrane between 

 rami of lower jaw whitish, without rosy wash, tip of lower jaw olivaceous; mouth 

 on sides and below tongue orange, whitish d-icwhci-c; side of caudal peduncle with 

 about 30 small roundish black spots, these nio'^t niinierous on posterior half, there 

 being only 3 anterior to the adipose doi'-al lin: rest (d' body eiitirel}' without spots; 

 dorsal fin with about 6 irregular series of Miiall roundish black spots, those toward 

 the distal portion largest and '■laikc'-t: general color of dorsal tin light olivaceous 

 yellow, the tips of the anterioi- iay> with a broad iiiargin (d' whitish orange; adipose 

 dorsal olivaceous, narrowly bordered with black, and with 2 small round lilacd^; spots; 

 caudal tin profusely spotted wilh black, the spots arranged irregularly in about S or 

 1(1 vertical i-ows; those at the lia^e blackest and roundest, those on the distal edge 

 somewhat linear, those on the outer edges of the lobes extending forward onto the 

 dorsal and \ cntial lines of ilic caudal peduncle; general color of caudal lin yidlowish 

 and olivaceous, the lower lobe somewhat rosy; pectoral red, somewhat lighter than 

 lateral band; ventral reddish, the anterioi- rays edged with white; anal reddish with a 

 little orange, the anterioi- half or two-thirds broadly edged with white. 



There is not iiuich variatiini in color, except such as is i)roliably <lue to difference 

 in age; the rosy lateral band, the parr-marks, and the broad rich cadniiuiii l)and on 

 the belly are characteristic. The \ariation in the black spots is inconsiderable. In 

 the 29 specimens which I have examined criticallj' 15 do not show any spots wdiateviM- 

 anterior to tlie adipose tin, and only 2 of the remaining 14 show any spots anterior 

 to the dorsal tin, and thes(> are obscure and few in number. In one large s])ecinien 

 there are but li' to 14 spots on tiie caudal peduncle: in anotlier somewhat smaller 

 example there are but t> spots. 'J'he dorsid, anal, and ventral tins are iinariably 

 edged with brighter color. The head in the males is longer and more pointed; the 

 maxillary is also longer than in the females. When well spread the caudal fin is 

 usually slightly lunate or slightly notched, but in some examples it is almost truncate 

 or square. In alcohol all of the liright colors soon fade, the parr-marks, black spots, 

 and ])ale edges to the dorsal, anal, and ventral tins persisting. The general color of 

 the body then becomes a dirty yellow ish white or in some spe(-iniens brownish. In 

 some eases the parr-marks almost wholly disappear. 



The type specimen of this species is No. 53064, U. S. Nat. Mus. Cotypes are 

 No. 53400, U. S. Nat. Mus.. No. 1251, Bureau of Fisheries, and No. i»255. Stanford 

 University. It gives nie great pleasure to nana* this .superb trout for Theodore 

 Roosevelt, in nN-ounition of his a(-ti\e interest in tisli and uauie ni-otectioii.
