Taxonomy and Distribution
of Some American Shrews

by James S. Findley

Sorex cinereus ohionensis Bole and Moulthrop.—In their description ofthis subspecies from Ohio, Bole and Moulthrop (1942:89-95) made nomention of specimens in the United States Biological Surveys Collectionfrom Ellsworth and Milford Center, Ohio, which stand in the literature(see Jackson, 1928:49) as Sorex cinereus cinereus. These twolocalities lie south of the geographic range ascribed to S. c.ohionensis by Bole and Moulthrop. Examination of the two specimens,United States Biological Surveys Collection, Catalogue No. 70566, andUnited States National Museum, No. 19434, respectively, both of whichare alcoholics, reveals that they are referable to the subspeciesohionensis rather than to S. c. cinereus. This reference is made onthe basis of small size, short tail (33 and 31 millimeters,respectively), and fourth upper unicuspid as large as third (thespecimen from Milford Center lacks the skull). The occurrence at MilfordCenter provides a southward extension of known range for S. c.ohionensis of approximately 70 miles. S. c. cinereus seems not tooccur in Ohio.

Cryptotis micrura (Tomes).—Davis (1944:376) assigned a Cryptotisfrom Boca del Río, Veracruz, to Cryptotis parva berlandieri (Baird).Comparison of this specimen, Texas Cooperative Wildlife Collections, No.2765, with 8 specimens of C. micrura from various parts of northernVeracruz and with 9 C. parva from southern Tamaulipas reveals that theshrew from Boca del Río is referable to Cryptotis micrura. The seriesof 8 specimens in the University of Kansas Museum of Natural Historyfrom Altamira, Tamaulipas, provides the southernmost known record ofCryptotis parva berlandieri. These 8 specimens are typical of C. p.berlandieri and show no approach to C. micrura. Average and extremecranial measurements of 7 specimens from 1 mi. S Altamira are:condylobasal length, 15.6 (15.2-16.1); palatal length, 6.6 (6.4-6.7);maxillary tooth-row, 5.7 (5.4-5.8); cranial breadth, 7.6 (7.4-8.0);least interorbital breadth, 3.5 (3.4-3.7); maxillary breadth, 5.0(4.8-5.2). Cranial measurements of 8 specimens of C. micrura[Pg 616] fromvarious localities in northern Veracruz (1 km. E Mecayucan, 1; 7 km. NNWCerro Gordo, 3; Teocelo, 2; 7 km. W El Brinco, 1; 5 km. N Jalapa, 1)are: condylobasal length, 17.1 (16.6-17.4); palatal length, 7.1(6.9-7.4); maxillary tooth-row, 6.2 (5.9-6.4); cranial breadth, 8.5(8.3-8.6); least interorbital breadth, 3.7 (3.6-4.1); maxillary breadth,5.3 (5.1-5.6). C. parva and C. micrura may intergrade but a distanceof 140 miles separates the geographic ranges as now known of the twokinds and every specimen examined by me is clearly referable to one ort
