102 Merriam — New North American Deer. 



blackish and enlarged, and with some fulvous hairs on upper side. Tarsal 

 gland normal, on inner side of calcaneum : metatarsal gland about 75-80 

 mm. in length, occupying approximately middle third (really a little 

 above middle third) of outer side of metatarsus. 



Cranial characters. — Skull similar in general to that of 0. hemionus cali- 

 fornicus hut smaller and lighter, with. decidedly longer nasals and very much 

 smaller teeth. The nasals are very narrow anteriorly, and are produced so 

 far posteriorly as to reach within 3 or 4 mm. of plane of hinder border 

 of anteorbital vacuities. The postero-lateral edge of the nasals abutting 

 against the anteorbital vacuity is nearly straight and so elongated that 

 its length equals the combined breadth of nasals on fronto-nasal suture. 

 The lachrymal pit is deep, but less so than in 0. h. californicus. The 

 anteorbital vacuity is decidedly larger than in californicus ; the orbitosphe- 

 noid decidedly narrower, and the anterior (sublachrymal) extension of 

 the jugal equally broad. The external openings of both of the lachrymal 

 ducts are on the inner side of the orbital rim. 



A ntlers. — The antlers are small, well bowed outward, with incurved tips, 

 and have only a single branch which is given off from the upper third of 

 the main tine and projects backward and upward. The largest antler of 

 five apparently adult' bucks in the collection measures only 190 mm. 

 from burr to tip in a straight line ; the spread between the tips is 230; 

 greatest spread at base of incurved tips 260. 



Measurements. — Type specimen, measured from dry skin: Total length 

 1560; tail vertebrae 180; hind foot 380 ; ear from crown anteriorly 180. 



Odocoileus thomasi sp. nov. 



Type from Huehuetan, Chiapas, Mexico, No. 77866, r? ad., U. S. Nat. 

 Mus., Biological Survey Coll. Collected Feb. 22, 1806, by E. W. Nelson 

 and E. A. Goldman, Orig. No. 9359. 



( 'haracters. —Size rather large ; color red all the year round ; tail as in the 

 Virginia Deer; metatarsal gland a very small spot on postero-external 

 aspect of metatarsus about midway between calcaneum and hoofs. 



Color. — Winter pelage (type specimen): Upper parts including side of 

 belly, middle of breast and neck all round, fulvous, becoming bright 

 grizzled golden fulvous on back; muzzle grayish dusky; forehead mixed 

 fulvous and black, becoming solid black in front of plane of ears, with a 

 fulvous spot over each eye posteriorly; chin white with a black spot on 

 each side of middle of lip, the spots nearly meeting on median line; in- 

 guinal region, inner side of thighs, middle part of belly, and posterior 

 aspect of forelegs, white. Tail: upper surface bright fulvous ; under sur- 

 face white. Summer pelage (Tonala, Chiapas, Aug. 10) : Similar, but 

 upper parts simply fulvous, lacking the grizzled golden appearance of 

 winter pelage ; forehead fulvous like rest of upper parts (lacking the black 

 of winter) ; muzzle dark grayish with a small dusky spot just behind nose 

 pad and another behind each nostril. [It is possible that the Tonala 

 specimen is not 0. thomasi.]
