     summary: In view of the absolute quality of the differences between _P. alcorni_ and _P. bulleri_, it seems best to regard the former as a species, rather than as a subspecies of _P. bulleri_. The conspicuous nasal patch of _P. alcorni_ is large and bright cinnamon or buffy, and, although the nasal patch may be large in some subspecies of _P. bulleri_, in each specimen possessing the patch the hairs are whitish with little or no trace of pigmentation.

     summary: Among named subspecies of _C. gymnurus_, the skull of _tellus_ most closely resembles that of _atratus_, and, although they differ greatly in size, _C. g. tellus_ seems to be the closest relative of _C. g. atratus_. Previously _C. gymnurus_ was known only from southern Jalisco and _C. zinseri_ only from extreme eastern Jalisco, but through the efforts of J. R. Alcorn specimens were obtained of both species in the central part of the state.

     summary: The field notes of the collector of the type of _T. u. pullus_ record that when he was making a shallow excavation to reveal the gopher burrow in which he trapped the holotype, he found the burrow approximately five inches below the surface of the ground and that in digging deeper than was necessary he accidentally broke into the burrow of a _Cratogeomys_. Thomomys umbrinus_ obtained in 1943 from points 3, 4 and 5 miles south of Pátzcuaro proves upon comparison to be an hitherto unrecognized subspecies which is described and named as follows: #Thomomys umbrinus pullus#, new subspecies _Type._--Male, adult, skin and skull; No. 100151, Univ.

     summary: T. t. rostralis_, which occur farther west, selected differences of _T. t. retrorsus_ are: lighter color; larger skull; more inflated tympanic bullae; greater relative (to length of skull) breadth across upper incisors, rostrum, and zygomata. T. t. retrorsus_ is indistinguishable in color, length of tail, and length of tooth-row, but averages smaller in all other measurements.
