150 Bangs — Tlie Squirrels of Eastern North America. 



Size. — Average measurements of fifteen adult specimens from Point aux 

 Loups Springs, Acadia Parish, Louisiana: total length, 541.5; tail ver- 

 tebrse, 252; hind foot, 73.7. 



General, remarks. — Sclurus ladoulclanns is blessed with a greater number 

 of synonyms than any other of our squirrels, owing to its enormous range 

 of color variation, and to the fact that it occu^Dies a large area of country. 

 The so-called Sclarus magaicaadatm of Harlan, from the Missouri River 

 region, will perhaps average a trifle smaller than Louisiana specimens, 

 and, as a rule, is a little paler in color, but the differences are trifling and 

 not worthy of subspecific recognition. 

 Specimens examined. — Total number, 44, from the following localities: 

 Louisiana : Point aux Loups Springs, Acadia Parish, 15 ; Grand 



Coteau, 2; Prairie Mer Rouge, 5. 

 Missouri: St. Louis, 3. 

 Indiana: Redfield,*4; Denver, 1.

 AVest Virginia and Pennsylvania, probably extending some distance south 

 in the Alleghany Mountains and higher land of Virginia and North Caro- 

 lina. Now rare and local throughout its range. 



Habitat. — The more heavily wooded and unsettled parts throughout its 

 range, apparently fast becoming extirpated. f

tThe Northern fox squirrel is one of the animals that cannot withstand 

 persecution and the clearing and settlement of the country. It is already 

 becoming very hard to get specimens of this subspecies. Dr. B. H. Warren, 

 Zoologist of the State of Pennsylvania, writes me that the northern fox 

 squirrel is practically extinct in Pennsylvania except in the counties of 

 Dauphin and Cumberland. I can get no information of any having been 

 taken lately in New Jersey and fear it has met the same fate in that State. 

 There seem to be a few left in the vicinity of the city of Washington.
