and North Carolina, the specimens are intermediate between those 

 from the previously mentioned northern and southern areas. The 

 difference in series of skulls is very noticeable, but it is difficult to 

 assign a definite distribution for a southern race and it seems hardly 

 proper to recognize one. The name Sorex personatus platyrhinus 

 (De Kay), 1 type-locality Tappan, Rockland County, New York, is 

 available should a southern subspecies of personatus ever be recog- 

 nized. 



The name Sorax personatus lesueurii (Duvernoy), based on a 

 specimen from the Wabash Valley, Indiana, has been used for a 

 southern form of personatus. As no specimen of a shrew of the 

 personatus type is known from southern Indiana, and the few speci- 

 mens collected in that region have all very surprisingly proved 

 referable to Sorex longirostris Bachman, it is obvious that the name 

 Amphisorex lesueurii Duvernoy is not applicable to a personatus 

 shrew. 2 The status of Sorex fimbripes Bachman, 1837, is discussed 

 below. 



SOREX FONTINALIS, new species. 



1895. [Sorex personatus] lesueuri Merriam, North Amer. Fauna, No. 10, p. 61, 

 December 31 (in part, as to specimen from Sandy Spring, Maryland). Not 

 Amphisorex lesueurii Duvernoy, 1842. 



Type. — From Cold Spring Swamp, near Beltsville, Maryland. 

 Cat. No. 85439, U.S.N.M. Skin and skull, old adult female. Col- 

 lected November 6, 1898, by Gerrit S. Miller, jr. 



General characters. — A diminutive shrew of the S. personatus group ; 

 smaller than personatus, with much shorter tail. 



Color. — Almost precisely like personatus. The type matches ex- 

 actly a skin of S. personatus from Highland Falls, New York, col- 

 lected in September. Upperparts dark sepia, darkest posteriorly; 

 sides lighter, about broccoli brown; underparts brownish gray; tail 

 distinctly bicolor, tip blackish. Specimens collected in February and 

 March are darker than the type, and a skin collected in May is much 

 browner. 



Skull and teeth. — Skull, compared with S. personatus, much smaller; 

 braincase narrow and compressed; rostrum shorter and relatively 

 wider, less attenuate. Teeth as in personatus, but unicuspids more 

 crowded and uniformly decreasing in size from first to fourth. 



Measurements. — Flesh measurements of type: Total length, 90 mm. ; 

 tail vertebra?, 31 ; hind foot, 10. (An average specimen of S. persona- 

 tus from the Catskills measures: Length, 99; tail, 40; hind foot, 12.) 

 Skull of type: Condylobasal length, 14.2; breadth of brain case, 7; 

 greatest anteorbital breadth, 3.9; length of bony palate, 5.6.

 synonymy of <S. longirostris.
