152 FIELD COLUMBI'AN MUSEUM ZOOLOGY, VOL. III. 



the six, four are entirely lacking beneath in ochraceous or yellow- 

 ish markings of any kind; one of the two remaining has a diamond 

 shaped yellowish white spot on the throat, and one smaller spot 

 on the breast, rest of under parts being a uniform chocolate 

 brown; the other specimen has a dark buff line on one side of tin 

 throat going to the breast and passing half way across the latter, 

 the rest of under parts being a uniform dark chocolate brown. 

 From M. a. caurina the present race differs in its paler head and 

 entirely differently colored under parts, and from M. a. actuosa 

 it can be distinguished by the characters given above. M. a. 

 kenaiensis is a very dark race with a pale head, nominally without 

 buff or ochraceous markings on the under parts and a long tail. 

 I sent two specimens, the type and one of the examples with buff 

 on the throat, to Mr. S. N. Rhoads, who has lately written a 

 review of the North American martens, requesting him to com- 

 pare them with the series of these animals in the Philadelphia 

 Academy's collection, and the following are some of his com- 

 ments kindly forwarded to me: 



' ' Color characters. Much darker and richer and more buffy 

 than actuosa. Upper body colors of brownish specimen quite 

 like caurina, but head paler and lower parts decidedly different, 

 being darker, lacking medium abdominal streak and large gular 

 and pectoral patches of caurina\ Lack of gular patches in one 

 specimen (the present type), unique so far as I have observed in 

 any species of New or Old World martens. Tail, feet and legs 

 showing greater contracted blackness throughout than any other. 

 Color relationship to abietinoides most remote to any species 

 examined; nearest to brumalis but hardly as dark, viz.: less 

 chocolate. 



" Size characters. Smaller than North Alaskan actuosa (typi- 

 cal), with relatively longer tail. Skulls . average considerably 

 smaller than those of actuosa of same apparent ages, and are 

 smaller than brumalis. I should say," he concludes, "that your 

 Kenai martens were a smaller, darker race of americana than 

 actuosa, producing on the Pacific coast most of the peculiarities 

 of the Atlantic coast brumalis, but separated therefrom by a vast 

 region tenanted solely by M. a. actuosa.
