TWENTY-EIGHTH ANNUAL MEETING 



and the fine fish cake, but tliey refuse to notice either, though 

 they will take it after- being taught to feed on liver emulsion. 

 The proper systematic place for the Montana grayling has 

 not yet been definitely settled. During the past year the name 

 ontariensis has been relegated and the former name tricolor 

 has been restored, so that the present name of the Montana 

 grayling is ThymaUus tricolor montanus (Milner). Jordan & 

 Evermann say it is: "Entirely similar to the Michigan gray- 

 ling, but the dorsal a little smaller.'' This I can not subscribe 

 to, as from examination of a large series of specimens this 

 spring I find the Montana grayling to be as closely allied to the 

 description of the Arctic grayling (T. sif/nifcr) as to the Mich- 

 igan form (T. tricolor), as the annexed table may show:

* Not having the fuU description of T. tricolor at hand will account for the omission 

 of some points in above table. 



The color of the Montana grayling is as follows: back, gray, 

 with purplish refiectious; sides, lighter, with purplish and sil- 

 very reflections; belly, pure white; a few V-shaped spots from 

 middle of dorsal fin to gill cover, but none posteriorly; two ob- 

 long black blotches in cleft between opercle and branchioste- 

 gals, more pronounced in the male; a dark heavy line on upper 

 edge of belly, running from veutrals to pectorals in male, very 

 faint in female. 



Dorsal fin edged with a red or rosy border; six or seven rows 

 of red or rosy, roundish spots, ocellated with w^hite; dark 

 blotches forming lines between the rows of red spots; in upper, 

 posterior angle there are several larger oblong rosy spots. Ven- 

 tral fins with three rose-colored stripes along the rays. Pec- 

 toral and anal fins plain.
