28 Merriam — Revision of the Coyotes. 



jiiw. Tlie upper cariiassial is much more i^wollen and broadly rounded 

 anteriorly, with a relatively insijjnificant inner cusp {pi-otocme) . The 

 first upper molar is very large and broad and is broadly rounded on the 

 inner side, without the posterior emargination of C. peiiiusujR\ The last 

 upper molar is suljquadrate and in contact with the first for nearly half 

 the length of the anterior face. The lower premolars and carnassial are 

 much larger, heavier, and more crowded than in peninsulx, but the pos- 

 terior molar is minute on one side and absent on the other (without trace 

 of alveolus). A very young skull from the volcano of Toluca, which has 

 not shed the milk teeth, has enormous audital bulke ; but very young 

 skulls of wolves always have larger bullae than adults. 



Remarks. — Hamilton Smith's original description of cagoitis is as follows : 

 " The Caygotte of the Mexican Spaniards, and most probably the Coyotl 

 of the native Indians, is a second species, but slightly noticed by trav- 

 elers. Mr. William Bullock observed it near Eio Frio, in the Mexican 

 Territory, and was informed by muleteers then with Iiim that it was the 

 Caygotte, a very fierce kind of wolf. The individuals lie saw were in size 

 equal to a hound, of a brownish rusty gray, with buff'-colored limbs, and 

 rather a scanty brush." While there is nothing distinctive about this 

 description, it may be assumed, on geographic grounds, to apply to the 

 animal from the Cerro San Felipe. For the same reason one would expect 

 Lichtenstein's C. nigrirostris to belong here also ; Ijut Lichtenstein states 

 that his animal has a black muzzle and short pointed ears, characters not 

 possessed by any Coyote known to me. Lichtenstein's specimen was col- 

 lected by Deppe at Real de Arriba, in the State of Mexico. If its skull 

 is still in the Berlin Museum, its relations to the Cerro San Felipe skull 

 may be easily ascertained. If not a freak it may be the large wolf of 

 southern Mexico.
