Since 1952 when Hooper's review of Latin American harvest micewas published, collectors from the Museum of Natural History ofthe University of Kansas have visited several countries in CentralAmerica, and have obtained many additional specimens. Amongthese we find a new subspecies of Reithrodontomys fulvescens fromNicaragua, significant extensions of known geographic range forseveral other species, and additional information on variation insome little known kinds. Specimens in the Museum of NaturalHistory of Reithrodontomys mexicanus cherriei, Reithrodontomystenuirostris, and Reithrodontomys creper that are from within thegeographic and altitudinal ranges listed by Hooper (1952) are notincluded in this report.
All place names are on the map of Hispanic America published by theAmerican Geographical Society and can be located by consulting the "Indexto map of Hispanic America" (Vol. 1, Geographical names in Central America,U. S. Government Printing Office, Washington, D. C., 1943.) All measurementscited are in millimeters.
Support for field work was provided by the Kansas University EndowmentAssociation. Support for the laboratory phases of the work came in part froma grant from the National Science Foundation. Most of the specimens hereinreported were collected by James W. Bee in late 1954 and early 1955, and byJ. R. Alcorn and A. A. Alcorn in 1955 and 1956. A few that were collectedearlier by other persons are mentioned. We are indebted to the followingindividuals for the loan of specimens in their care: R. G. Van Gelder, AmericanMuseum of Natural History; Philip Hershkovitz, Chicago Natural History Museum;W. H. Burt and E. T. Hooper, Museum of Zoology, University ofMichigan; and D. H. Johnson and C. O. Handley, Jr., U. S. National Museum.

One female, KU 26967, trapped on March 2, 1947, on the SWslope of Volcan Irazú, 8500 ft., contained five embryos that were17 mm. in crown-rump length.[Pg 522]
