KNOX JONES, JR. Since 1952 when Hooper's review of Latin American harvest mice was published, collectors from the Museum of Natural History of the University of Kansas have visited several countries in Central America, and have obtained many additional specimens. Among these we find a new subspecies of _Reithrodontomys fulvescens_ from Nicaragua, significant extensions of known geographic range for several other species, and additional information on variation in some little known kinds. Specimens in the Museum of Natural History of _Reithrodontomys mexicanus cherriei_, _Reithrodontomys tenuirostris_, and _Reithrodontomys creper_ that are from within the geographic and altitudinal ranges listed by Hooper (1952) are not included in this report. All place names are on the map of Hispanic America published by the American Geographical Society and can be located by consulting the "Index to map of Hispanic America" (Vol. 1, Geographical names in Central America, U. S. Government Printing Office, Washington, D. C., 1943.) All measurements cited are in millimeters. Support for field work was provided by the Kansas University Endowment Association. Support for the laboratory phases of the work came in part from a grant from the National Science Foundation. Most of the specimens herein reported were collected by James W. Bee in late 1954 and early 1955, and by J. R. Alcorn and A. A. Alcorn in 1955 and 1956. A few that were collected earlier by other persons are mentioned. We are indebted to the following individuals for the loan of specimens in their care: R. G. Van Gelder, American Museum of Natural History; Philip Hershkovitz, Chicago Natural History Museum; W. H. Burt and E. T. Hooper, Museum of Zoology, University of Michigan; and D. H. Johnson and C. O. Handley, Jr., U. S. National Museum.
