NORTH AMERICAN FAUNA. 



[No. 10. 



mandible mucli less massive and with only a trace of tlie angle of the 

 ramus 5 ui^per lateral incisors relatively broader at base and more 

 nearly vertical (not sloping strongly forward); first premolar (5th uni- 

 cuspid) usually not visible from outside. 



Measurements. — Average of 6 specimens from Columbia, S. C. (pre- 

 sumably near type locality): Total length, 99.5 mm.; tail vertebrse, 

 20.5 mm.; hind foot, 12.5 mm. Average of 9 specimens from Washing- 

 ton, Miss.: Total length, 94 mm.; tail vertebrae, 20 mm.; hind foot, 

 12.2 mm. 



General remarJcs. — Blarina carolinensis is merely a small edition of 

 B. hrevicaudaj lacking the more accentuated features of the latter in 

 the way of massiveness and angularity of the skull and lower jaw. It 

 differs also in the lateral unicuspidate teeth. They are more nearly 

 vertical and the fifth is generally hidden when viewed from the outside. 



In geographic distribution it is strictly confined to the Austroripa- 

 rian fauna. It thus inhabits the southern half of the region inhabited 

 by B. parva, and the two occur together in many localities. 



Blarina carolinensis was described by Bachman in 1837, and has had 

 the good fortune to escape synonyms. It is intermediate in size, but 

 not in characters, between the northern Blarina hrericaudaj^ith which 

 it intergrades, and the southern B. parva, from, which it differs subge- 

 nerically (having 32 instead of 30 teeth). Intergrades with hrevicauda 

 are confined to a narrow strii) just above the upi)er edge of the Austro- 

 riparian zone. Such intergrades have been examined from Cape Charles, 

 Ya. ; Eubank, Ky. ; Kimmswick, Mo., and the following places in south- 

 ern Indiana: Brookville, 'Ne^Y Harmony, Tigo County, and Putnam 

 County. Specimens from Eichmond, Ind., are nearer hrevicauda than 

 caroli7iensis.
