“ An unusual amount of variation exists, but it seems to occur at random. Fixing type localities of the two subspecies at the places of origin of certain specimens which in color fit the original descriptions is meaningless because selected specimens or series from almost any place in the geographic range of the species would qualify as approximate color-duplicates of the types. ”

“ Nevertheless, although the essential morphological characters of S. a. frumentor occur sporadically in other populations, the [Pg 248] animals from the higher elevations above Jico and Las Vigas are notably homogeneous, differ collectively from surrounding populations, and occupy a logical geographic range. Therefore S. a. frumentor is retained as a tenable subspecies, and the animals from the vicinity of San Marcos, and from San Carlos and Plan del Río are referred to S. a. aureogaster. Incidentally, Nelson (op. cit.:45) remarks that he saw no melanistic specimens of S. a. frumentor. ”

Range.—Higher elevations of the Cofre de Perote. Marginal localities, both in Veracruz, are: Above Las Vigas; Jico.
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. ”
