aureogaster hypopyrrhus Nelson, Proc. Washington Acad. Sci., 1:42, May 9.

Range.—Eastern slope of Mexico from southern Tamaulipas southward to Tabasco and Chiapas. Marginal localities arranged clockwise beginning with the northernmost station of record are: Tamaulipas: Victoria; Altamira; down the coast to Veracruz: Coatzocoalcos; inland to Tabasco: Montecristo. Chiapas: Tumbala. Oaxaca: Mountains near Santo Domingo. Veracruz: Otatitlan; Orizaba; Jico; Jalapa. Puebla: Metlaltoyuca. Hidalgo: Sierra Encarnacion. Querétaro: Pinal de Amoles. San Luis Potosí: Valles. Tamaulipas: Forlón. Specimen No. 51383 Chicago Mus. Nat. Hist., labelled as from San Luis Potosí, in the State of the same name, does not represent, I suspect, a natural occurrence of the animal. Possibly the specimen was purchased there in the market, but was actually captured elsewhere.

This report is based on the examination of 256 specimens representing the entire known geographic range of the species. I am indebted to H. E. Anthony, Remington Kellogg, C. C. Sanborn, and Stanley P. Young for the privilege of examining specimens in their charge. The study here reported upon was aided by a contract between the Office of Naval Research, department of the Navy, and the University of Kansas (NR 161-791). The specimens in the University of Kansas Museum of Natural History were obtained by field work supported by the Kansas University Endowment Association.
