226 MAMMALS OF PENNSYLVANIA AND NEW JERSEY. 



vicinity of Washington, D. C. Being more of a lowland dweller, it may only 

 be sought for in the lower Susquehanna valley. The Delaware Bay and Val- 

 ley form a natural barrier to its dispersion in southern N. J., whose faunal 

 conditions would be more favorable to its peculiar needs than anywhere in 

 Pa. 



Batchelder's Shrew. Sorex macrurus Batchelder. 



Hoy's Shrew. Sorex hoyi Baird. 



Lesuenr's Shrew. Sorex personatus Usueuri (Duvernoy). 



Fisher's Shrew. Sorex hngirostris fisheri (Merriam). • 



Of these, macrurus and hoyi may be looked for in north Pa., lesueuri in 

 west Pa., and fisheri in southern N. J. They can only be distinguished by 

 critical and expert examination of the teeth. Hoy's shrew, however, is strik- 

 ingly grayer than any other in Pa., and Batchelder's has a very long, thick tail 

 as compared with the rest. They are all as small as or smaller than personatus, 

 a description of which has been already given. 



Big-eared Bat. Corynorhinus macrotis (Leconte) . 



The only allusions to the occurrence of this southern bat in our limits are as 

 follows : " I am informed by Prof. Baird that specimens of a Synous, proba- 

 bly of this species, were received some years ago by the Smithsonian Institu- 

 tion from Meadville, Pa., but that they have become in some way misplaced 

 and are not now to be found." — H. Allen, Monog. Bats, N. Amer., 1864, 

 p. 64. 



" On the authority of Prof. Baird it has been obtained at Meadville, in 

 northwestern Pennsylvania. At my request, Prof. J. H. Montgomery, of Alle- 

 ghany College, Meadville, recently collected a number of bats Irom this 

 neighborhood, but has not succeeded in procuring Corynorhinus" — H. 

 Allen, Monog. Bats N. Amer., 1893, p. 5 7. 



While it is Aot impossible that a flying animal, normally found as far north 

 as the Carolinas, might be driven by storm so far from its habitat, this record 

 is open to doubt. Much less does it indicate the probability of its recur- 

 rence in our southern limits.
