Soricidae of Arizona

Abstract

A number of records not heretofore reported and a lack of distributional data of Arizona soricids prompted the author to report on the distribution of Soricidae in Arizona using all available records. Insectivores in Arizona are represented by five sp,ecies of shrews.: Sorex vagrans monticola Merriam, S. merriami leucogenys Osgood, S. nanus Merriam, S. palustris navigator (Baird), and Notiosorex crawfordi crawfordi (Coues). S. vagrans is represented by 126 specimens, S. merriami by six, S. nanus by two, S. palustris by three, and Notiosorex by 27. Each species account consists of the altitudinal range, geographical distribution, ecological distribution, and records of occurrence. The following abbreviations are used with the records of occurrence: BS . . . United States Fish and Wildlife Service, Biological Survey Collections, Washington, D. C. Carnegie . . . Carnegie Museum, Pittsburgh, Pennsylvania. CMNH . . . Chicago Museum of Natural History. MVZ . . . Museum of Vertebrate Zoology, University of California, Berkeley. RWD . . . collection of Robert W. Dickerman. SDSNH . . . San Diego Society of Natural History, San Diego, California. UA . .. Department of Zoology, University of Arizona, Tucson. UI . . . Department of Zoology, University of Illinois, Urbana. UM ... Department of Zoology, University of Michigan, Ann Arbor. A distribution map for each species and a master locality map (Fig. 1) are included within the body of the report.
