ere lactating. ~Heterogeomys hispidus concavus~ Nelson and Goldman Hispid Pocket Gopher _Heterogeomys hispidus concavus_ Nelson and Goldman, Proc. Biol. Soc. Washington, 42:148, March 30, 1929. (Type from Pinal de Amoles, Queretaro, Mexico.) _Specimens examined_, 5 as follows: 70 km. [by highway] S Ciudad Victoria and 5 km. W El Carrizo, 4; 70 km. [by highway] S Ciudad Victoria and 2 km. W El Carrizo, 1. _Remarks._--These gophers have been compared with specimens of _H. h. hispidus_ from Veracruz (5 km. N Jalapa and 4 km. WNW Fortin) and with specimens of _H. h. concavus_ from San Luis Potosi (Xilitla and vicinity and 3 mi. NW Pujal); the latter were examined through the courtesy of Dr. George H. Lowery, Jr., of the Museum of Zoology at Louisiana State University. These five specimens are assigned to _H. h. concavus_ and resemble in every way this subspecies except: slightly smaller, somewhat darker, and skull with lambdoidal crest less inclined forward. In the latter feature, the single skull available seems to resemble most closely that of _H. h. hispidus_. Unfortunately, all but one skull, that of a subadult female, were destroyed in the field. This is the first known record of this genus in Tamaulipas and the most northern locality from which specimens have been taken. At this latitude, the gopher appears to be restricted to the humid belt on the east face of the Sierra Madre Oriental. These large gophers were difficult to trap by ordinary means; Schaldach got two by using large-sized Macabee traps but the others were taken at night either with the aid of a dog or by natives with slingshots. ~Liomys irroratus texensis~ Merriam Spiny Pocket Mouse _Liomys texensis_ Merriam, Proc. Biol. Soc. Washington, 15:44, March 5, 1902. (Type from Brownsville, Cameron County, Texas.) _Liomys irroratus texensis_ Goldman, N. Amer. Fauna, 34:59, September 7, 1911. _Specimens examined_, 15 as follows: 7 km. S and 2 km. W San Fernando, 8; 36 km. N and 10 km. W Ciudad Victoria, 1 km. E El Barretal, on Rio Purificacion, 1; 70 km. [by highway] S Ciudad Victoria and 2 km. W El Carrizo, 6. _Remarks._--Most of these mice were taken in densely vegetated fallow fields, where both grass and brush were found. Many of the mice were captured at their burrow openings, some of which were found to be plugged and others not plugged. ~Reithr
