LASIURUS BOREALIS SEMINOLUS (Rhoacls). 

 1895. Atalapha IwreaUs scminoJa Rbonds, Pruc. Acad. Nat. Sci. Phila., p. 32. 



TijjJe locality. — Tarxwu Springs, Fla. 



Geographic distrihutiou. — Lower Austral and Tropical zones from 

 South Carolina to southern Texas. 



General cJiaracfers. — In size and proportions similar to typical Lasi- 

 ijrvs horealis; general color mahogany brown, slightly frosted with 

 grayish. 



Uars, membranes^ feet ^ and distribution of fur. — In all external char- 

 acters except color Lasiurus horealis seminolus agrees with typical 

 horealis. 



Color. — General color rich mahogany brown throughout, the back 

 (especially between the shoulders) slightly frosted with gray and the 

 throat and chest varied with whitish. A distinct whitish area in 

 front of slioulder as in true horealis. 3Iuzzle, bachs of ears, and fur 

 bordering forearm, yellowish brown. Clump of fur at base of thumb 

 Avliitish or yellowish. On middle of back the fur is about 12 mm. in 

 length. In this region the colors on the individual hairs are arranged 

 in four bands as follows: Basal band deep blackish x^himbeous (this 

 band usually broader than in true horealis), middle band light gray, 

 si;bapical band rich mahogany, extreme tip grayish white. 



Color variation in Lasiurus horealis seminolus is much less than in 

 typi( al horealis, and is chietly noticeable in the amount of red in the 

 mahogany brown, in the amount of white on the throat and chest, and 

 in the shade of gray in the broad middle band on the hairs of the 

 back. This is often strongly sutfused with yellowish. 



Skull and teetli. — As in typical horealis. 



Measurements. — See table, page 115. 



Specimens examined. — Total number, 19, from the following localities: 



Florida: Old Town, 3 (skins, Miller coll.) ; Lake Harney, 2. 

 Georgia: Nashville,!. 

 Louisiana: New Orleans, 5. 

 Mississippi: Bay St. Louis, 3. 



South Carolina: Mount Pleasant (near Charleston), 4. 

 Texas: Brownsville,!. 



• General remarlxS.— Lasiurus horealis seminolus apx)ears to be a well- 

 marked subspecies confined to the Austroriparian fauna. The single 

 specimen taken at Brownsville, Texas (No. 59'J7G, U. S. National 

 Museum) was killed on September 8, 1891, and may have been a migrant. 

 Xo intermediates between seminolus and true horealis has yet come to 

 light, but the i^erfect agreement of the two forms in all charaters 

 except color makes me unwilling to recognize them as species. The ]30S- 

 sibility that seminolus and true horealis are dichromatic phases of one 

 species lacks weight on account of the total absence of intermediate 

 specimens, and also from the fact that both forms have not yet been 

 found breeding at any one locality.
