A New Bat (Genus Leptonycteris) From Coahuila
BY HOWARD J. STAINS Assistant Professor, Department of Zoology, Southern Illinois University
In a collection of mammals obtained in Coahuila, Mexico, there is a series of 24 long-nosed bats, _Leptonycteris nivalis_. These bats have a larger skull and a longer third finger than other bats of this species found to the south of Coahuila. On the basis of these distinctive characters, it seems appropriate to recognize these long-nosed bats from Coahuila as belonging to a new subspecies, named and described as follows:
#Leptonycteris nivalis longala# new subspecies
_Type._--Female, adult, skin and skull, No. 33087, Univ. Kansas Mus. Nat. Hist.; 12 mi. S and 2 mi. E Arteaga, 7500 ft., Coahuila; 11 July 1949; obtained by W. K. Clark, original number 787.
_Range._--Southern Coahuila north to the Big Bend (Brewster County) of Texas.
_Diagnosis._--Size large (see measurements); third finger long; color pale, upperparts Hair Brown (capitalized color terms are after Ridgway, Color Standards and Color Nomenclature, Washington, D. C., 1912), underparts Smoke Gray; skull large and broad.
_Comparisons._--From _Leptonycteris nivalis nivalis_ (specimens from Veracruz, Oaxaca, Distrito Federal, Hidalgo, Jalisco, and Sonora), _L. n. longala_ differs as follows: color paler, more whitish and less brownish; third finger longer (_longala_ from Coahuila averaging 111.3 mm.; _nivalis_ from Sonora averaging 91.0, from Jalisco 96.4, from Hidalgo 98.0, from Veracruz 100.0, from Distrito Federal 100.2, and from Oaxaca 98.6); skull larger, breadth of cranium greater (_longala_ from Coahuila averaging 10.7 mm.; _nivalis_ from Sonora 9.8, from Jalisco 9.8, from Hidalgo 9.6, from Veracruz 9.9, from Distrito Federal 9.9, and from Oaxaca 9.8); mastoidal breadth greater (_longala_ from Coahuila averaging 11.6 mm.; _nivalis_ from Sonora 10.5, from Jalisco 10.8, from Hidalgo 10.6, from Veracruz 10.9, from Distrito Federal 10.8, and from Oaxaca 10.7); skull higher (_longala_ from Coahuila averaging 10.0 mm.; _nivalis_ from Sonora 9.3, from Jalisco 9.2, from Hidalgo 9.2, from Veracruz 9.3, from Distrito Federal 9.3, and from Oaxaca 9.1). The average of each dimension of _longala_ listed above exceeds the maximum of the corresponding dimension in _nivalis_.
