Distribution in Tamaulipas.—Reported from only one locality, in northwestern part of state.
The skull examined, of an adult male, differs from Coahuilan and New Mexican skulls in having a broad rostrum, better developed sagittal and lambdoidal crests, and smaller tympanic bullae. The measurements are greater than those given by Schantz (1949:302) for T. l. littoralis and it is for that reason that the skull examined is assigned to T. l. berlandieri.
Measurements.—The adult male measured as follows: 710; 115; 110; 55; condylobasal length, 123.1; zygomatic breadth, 81.1; mastoid breadth, 75.5; interorbital constriction, 29.3; least postorbital constriction, 27.6; length of maxillary tooth-row, 42.7; P4, length, 11.9, width, 10.7; M1, length, 11.7, width, 11.7; tympanic bulla, length, 23.3, depth (from basioccipital), 12.8.
Record of occurrence.—One specimen examined from 12 mi. S San Carlos, 1300 ft.
