NORTH AMERICAN FAUNA. 



LASIURUS BOREALIS PFEIFFERI (Gundlacli). 



1861. Ata^apha pfeifferi Gundlacli, Monatsber. K, Preuss Akad. Wiss., Berlin, p. 152. 

 1878. Atcdaplia novehoracensls var. fJ {AiaJaplia pfeifferi) Dobsou, Catal. Chiroptera 

 Brit. Mns., p. 271. 



1892. Atalaplia noveboracensis pfeifferi Cliapmau, Bull. Am. Mus. Nat. Hist., IV, p. 316. 



Type locality. — Cuba. 



Geographic distribution. — Cuba. Jamaica? Bahamas^ 



General characters. — Sligbtly larger tban typical Lasiurns horealis, 



but similar in proportions; color brighter and more intense. 



Uars, menihranes, feet, and distribution of fur. — As in the typical 



subspecies. 



Color. — I have seen no skins of the Cuban reel bat, and am therefore 

 unable to give a detailed description of the animal's color. The two 

 specimens collected by Mr. Chapman in 1892 have now been in alcohol 

 for five years. Hence their color furnishes no trustworthy basis for 

 comparison with that of continental material. When compared with 

 alcoholic specimens from the eastern United States they are appreci- 

 ably brighter. 



Measurements. — See table, i)age 115. 



Specimens examined. — Two from Trinidad, Cuba (Am. Mus. ^^at. 

 Hist.). 



A skull from Nassau, Bahamas (Miller coll.), and an imperfect skin 

 from Spanish town, Jamaica, may be referable to this race, but it is not 

 possible to identify them with certainty. 



General remarhs. — Lasiurus boreaUs pfeifferii% a tolerably well-marked 

 insular form, distinguished from typical borealis by its slightly larger 

 size and brighter color. 



LASIURUS BOREALIS TELIOTIS (H. Allen). 



1891. Atalaplia teliotis H. Allen, Proc. Am. Philos. Soc, XXIX, p. 1. 



1893. AtaJapha teliotis H. Allen, Monogr. Bats N. Am., p. 153. 



Type locality. — Unknown, probably some part of California (type in 

 U. S. ^^"ational Museum). 



Geographic distrihution. — This form is know^n from a few localities in 

 California and Lower California from the head of the Sacramento Valley 

 south to Comondu. 



General characters. — Slightly smaller than tyi)ical Lasiurus borealis; 

 ear proportionally much shorter than in the typical subspecies, and 

 with external basal lobe greatly reduced in size; color averaging 

 brighter than in the typical form. 



Ears. — The ear (fig. 21b) is similar in form to that of typical borealis, 

 except that the tip is slightly narrower and the external basal lobe is 

 reduced in size, indistinctly marked oft' from the rest of the ear, and 

 scarcely, if at all, notched on its anterior border. 



i\Iembranes, feet, and distrihution of fur. — The external form, with the 

 exception of the size and shape of ears, is as in true borealis. 



Color. — I have seen only four skins of the Californian red bat. In
