tlian in fiilvus ; tail rich dark fulvous, with basal ring like back; rest 

 of tail, except white tip, bountifully mixed with black hairs, most 

 abundant below. 



Skull. — Size essentially the same as fulvus of corresponding sex ; 

 similar to fulvus in general characters, but rostrum slightly more 

 swollen ; teeth larger. Premolars larger, more swollen, and less 

 spaced; carnassials larger ; ist upper molar larger. 



MeasurefJients. — Type specimen ( 9 old) : total length 1077 ; tail 

 vertebra 401 ; hind foot 166 (from Bangs). 



VULPES RUBRICOSA BANGSI subsp. nov. 



Type from Lance au Loup, Labrador. No. 8880, 9 (young of 

 year), Bangs Coll. Oct. 3, 1899, Ernest Doane. 



Range. — Labrador — limits vmknown. 



Characters. — Similar externally to fulvus but ears smaller ; black 

 of ears and feet more restricted. Skull as in rubrlcosa and deletrix. 



Color. — Upperparts golden fulvous, ?is in fulvus \ tail bountifully 

 mixed with black hairs, as \x\. fulvus and allied forms ; black of ears re- 

 stricted to apical half or less ; black of fore and hind feet not reaching 

 up on legs. 



Skull. — Very close to rubrlcosa., from which it differs chiefly in 

 greater narrowness, particularly of the zygomata and posterior part of 

 palate, and in slightly larger teeth. The differences, however, do not 

 appear to be constant or reliable — see remarks under deletrix. 



Measure?nents. — ( S , not full grown, measured in flesh by collector) : 

 total length 964 ; tail vertebrae 378 ; hind foot 168; ear from notch 88.

 PI. XXXVII, fig. 2. 

 Vulpes deletrix Bangs, Proc. Biol. Soc. Washington, Vol. xii, pp. 36-38, 

 Mar. 24, 1898. 



Type locality. — Bay St. George, Newfoundland. 



Range. — Newfoundland . 



Characters. — Color very pale — light straw yellow, deepening in 

 places to golden yellow or even buffy fulvous ; black of feet restricted ; 

 tail pale buffy yellowish w4th usual admixture of black hairs, but with- 

 out black basal spot. Hind feet and claws very large (about 160 in 9 ) . 



Skull. — Very close to that of rubrlcosa but a\'eraging narrower ; 

 zygomata less spreading in male ; bullae usually larger ; teeth usually 

 more swollen. Still, the resemblance is exceedingly close and I have 

 been unable to find any positive character by which skulls of New-
