A DESCRIPTION OF THE GOLDEN TROUT OF KERN RIVER, CALI- 
FORNIA, SALMO MYKISS AGUA-BONITA. 
By David STaRR JORDAN. 
I-have lately received from Mr. W. H. Shockley, of San Francisco, 
_ three specimens, each about 7 inches in length, of the Golden Trout of 
Kern River. These specimens were taken by Mr. Harvey, of Lone 
_ Pine, Cal., in a stream called by him Whitney Creek (more correctly 
— Voleano can on the west side of the Sierra Nevada, near Mount 
Whitney. The specimens were sent in ice to Mr. George T. Mills, fish 
- commissioner of the State of Nevada, who forwarded them to Mr. Shock- 
ley. The following is a detailed description: 
Salmo mykiss agua-bonita, new subspecies. 
| Head,3? inlength; depth, 4%. D.2,12. A. 1,10. Scales, 180 to 200 
-TOWS; 121 to 124 pores. Length, 7 ones 
_ Body formed about the same as usual in Salmo mykiss and its varie- 
ties. Head rather long, bluntish at tip; mouth moder ate, the max- 
 illary extending a little beyond the eye, 14 in head; hyoid teeth not 
_ evident; opercle moderate, its greatest length 44 in head, its posterior 
_ mInmargin moderately convex; eye, 4% in head; snout, 44; gill rakers not 
_very short, X + 11 or 12 in number. 
Seales extremely small, smaller than in any other species of Salmo. 
|| Fins moderate; the anal high; the caudal moderately emarginate. 
|) Pectoral, 14 in head; ventral, 2; caudal, 12. 
Olive above; sides and ally light golden. About twelve dark cross- 
| bars on middle of sides; these the usual parr-marks. Middle of sides 
: along lateral line with a deep scarlet lateral stripe, broadest under the 
| dorsal, where it is about as wide as the eye; thence narrowing to either 
end and not reaching either head or caudal. Middle line of belly with 
_ abroad scarlet band, extending from chin to anal fin, equally bright 
all the way; a fainter shade along lower side from anal fin to tip of 
caudal. No crimson dash at fardat between branches of lower jaw; 
the whole region uniform bright orange. Opercle largely orange. 
Dark spots chiefly posterior as in S. spilurus and pleuriticus; large and 
well marked, some on tail and posterior part of body as large as pupil; 
| Smaller and well marked on dorsal; a few small ones scattered along 
_ forward to the head in two specimens; none on body before adipose fin 
in the other. 
| Upper anterior angle of dorsal abruptly yellowish white; this color 
| edged by a dark oblique streak, made by coalescent spots; the rest of
