we consider that brevicauda and carolinensis have been pretty con- 

 clusively proved to intergrade in western North Carolina and Ten- 

 nessee. For the present, however, it is more logical to assume that 

 the two so-called ' brevictmda' specimens from Chapanoke are im- 

 mature telmalestes, that telmalestes does wander beyond the confines 

 of swamps and that it in no case intergrades with its neighbor caro- 

 linensis nor ever overlaps the habitat of brevicauda, from which it 

 should, therefore, be considered a distinct species. 6 



15. Blarina brevicauda carolinensis (Bachm.). Carolina Mole Shrew. 



The difference in size between the small adult mole shrew from 

 Chapanoke in the Rkoads' collection and the large specimens already 

 referred to under telmalestes, is so great as to allow no question of 

 a possible intergradation. The skull of the former barely measures 

 19 mm. in total length, while the latter average nearly 23 mm. 

 The hind foot of the former is 11 mm. long, that of the latter 14 

 mm. 



16. Sorex fisheri Merr. Fisher's Shrew. 



" One specimen was secured in a runway in pine woods at Chap- 

 anoke." The color and measurements of this specimen, which is 

 just reaching maturity, are intermediate between those given re- 

 spectively for longirostris and fisheri in Dr. Merriam's " Revision " 

 of the genus. The two may eventually be found to intergrade on 

 the outskirts of Dismal Swamp. 



SUPPLEMENTARY LIST OF SPECIES NOT OBSERVED BY MR. YOUNG 

 BUT REPORTED TO HIM BY OTHERS. 



1. Didelphis marsupialis virginiana (Kerr). Virginia Opossum. 



" Said to be common at both Chapanoke and Currituck." 



2. Dorcelaphus americanus (Erxl.) Virginia Deer. 



"Said to be not uncommon in the wild regions about Chapanoke." 



3. Sciuropterus volans (L.). Carolinian Flying Squirrel. 



" Reported at Chapanoke." 



4. Ursus americanus Pallas. American Black Bear. 



" Not rare in the wilder sections of country near Chapanoke." 



6 A specimen of typical brevicauda, recently taken in eastern Gloucester 

 County, Virginia, indicates not only that telmalestes is connected with the north- 

 ern form but that carolinensis is a distinct species whose habitat overlaps 

 brevicauda in these regions.
