64 TAGASSU. 
Genl. Char. Sexes nearly alike in color and size. 
Color. Similar to T. angulatum, but “‘sides decidedly whiter; 
shoulder stripes broader and more conspicuous and somewhat sub- 
triangular, broadest where they abut against the median dorsal black 
band, which is well developed; (shoulder stripes broadest and most 
striking in young); pelage coarser and scantier, the individual bristles 
decidedly larger and fewer in number; no black on nose or under- 
lip.”” (Merr.) 
Measurements. Total length, 880; tail, 36; hind foot, 183.

Genl. Char. Similar to T. angulatum, but larger; bristles large 
and rigid; dorsal stripe ill defined; ‘‘anterior opening of antorbital 
foramen between second and third premolars.’’* (Merr., 1. c.)

or obsolete; hind legs grizzled black and fulvous. 
Measurements. Total length, 950; tail, 54; hind foot, 203.

SONORA PECCARY. 
Type locality. San Bernardino River, State of Sonora, Mexico, 
near Monument No. 77, Mexican boundary line. 
Geogr. Distr. State of Sonora, Mexico, into Arizona. 
Genl. Char. Larger than T. angulatum, with smaller and simpler 
molars. 
Color. Above mixed grayish and yellowish white and brownish 
black; indistinct whitish color across neck and in front of shoulder; 
muzzle, cheeks and space before eyes brownish gray; under jaw 
yellowish, triangular black patch on chin; ears black; limbs brownish 
white and black, with a light band above accessory hoofs on fore legs; 
under parts blackish; grayish on axillar and inguinal regions; snout 
plumbeous; hoofs plumbeous black; mane of black-tipped bristles 
from crown to gland on rump. Young pale reddish brown, with 
black vertical stripes. 
Measurements. Total length, 920; tail vertebre, 65; ear from 
crown, 115; height at shoulder, 610; hind foot, 200. 
* The position of the opening of the antorbital foramen is not a dependable 
character, for in a series of skulls from Texas and Mexico, this opening is found 
to be between the second and third premolar, over the third premolar (both 
specimens from the same locality),and between the third premolarand the first 
molar, and is thus shown to vary greatly.
