STATUS OF THE PRONGHOBNED ANTELOPE, 1922-1924 63 
CHIHUAHUA 
111 extreme northwestern, southeastern, and eastern Chihuahua antelope 
occur in varied numbers. The bands in the extreme northwestern part are 
separated from those which range along the Mexican Central Railroad to the 
east. The great Bolson de Mapimi and the region east of the Mexican Central 
Railroad is a vest territory ideally suited to the needs of these animals. In 
southern Chihuahua antelope occur on both sides of the Mexican Central Rail- 
road, particularly along the border of Durango. 
DURANGO 
In Durango antelope are now limited mainly to the northeastern part of the 
State, in the district of San Dimas. Antelope are reported to be rather com- 
mon in the follo\Aing local- 
ities : L a p i o r i z, Mara- 
velles, El Filar, Santa 
Rita, San Julian, Las La- 
g-unas, Huachinepas, San 
Francisco de los Lobos, 
Pericos, and Huahiapa y 
Gavilanes. They are also 
said to be abundant in the 
district about Escalon, 
along the border of Chi- 
huahua and Durango, near 
the base of the Sierra del 
Diablo. 
so NORA 
Antelope in Sonora are 
practically all west of the 
railroad extending from 
Nogales on the Arizona 
border south to Guaymas 
and in the region lying 
north of a line drawn from 
Hermosillo west to the 
coast of the Gulf of Cali- 
fornia. A few bands in 
northwestern Sonora 
range back and forth across the Arizona border. It is these bands which are 
now under the guardianship of the Permanent Wild Life Protection Fund. 
Under date of January 4, 1925, Ben Tinker, who represents the Permanent 
Wild Life Protection Fund along the Sonora-Arizona border, supplied the 
writer with interesting information concerning the distribution of the sur- 
viving antelope in Sonora. They are reported to occupy 4 areas and to have 
totaled 595 animals in November, 1924, when they were counted by him. Fol- 
lowing is his summary of these antelope herds: 
1. Comprises numerous bands, numbering 459 all told, ranging from the 
southern end of the Sierra Rosario south and east to the Sierra Blanca and 
the Rio Sonoyta, thence eastward (north of Sierra Pinta) to the eastern side 
of the Sierra de San Francisco. The largest single band, containing 73 ani- 
mals, ranges between the Sonoyta River and Sieita de San Francisco during 
the months of October, November, and December and southward from this 
river to the Sierra Pinta during the remainder of the year.
