_Comparisons._--For comparisons with _B. t. subater_, _B. t. analogous_, and _B. t. fuliginatus_, see accounts of those subspecies. From _B. t. paulus_, found to the southwest, _B. t. taylori_ differs as follows: dorsum grayish rather than fawn-colored; hairs on dorsal parts of forefeet and hind feet sooty-gray (not white to white-brown); venter gray to Light Drab-Gray, rather than whitish with gray overtones; tail unicolored instead of bicolored; skull averaging slightly larger over-all; maxillary part of zygoma forms right angle with rostrum rather than obtuse angle; incisive foramina extending posteriorly to anterior plane of first upper molars instead of to a transverse plane at middle of right and left first upper molars; bullae less inflated; interorbital region broader relative to length of skull; rostrum sloping gently from frontonasal suture to anterior tip of nasals rather than declining abruptly from frontonasal suture to anterior tip of nasals. _Remarks._--The geographic range of _taylori_ is relatively large, and the subspecies is locally variable. Nevertheless, none of the external and cranial measurements of specimens assigned to this subspecies differs significantly from the corresponding measurements of material from the type locality and adjacent areas in southeastern Texas. In southeastern Texas, south of the Guadalupe River, south to the coastal plain of Tamaulipas, this subspecies differs in color (being paler) from _B. t. subater_ with which _taylori_ might be confused. The foothills of the Sierra Madre Oriental in western Tamaulipas, north through Nuevo Leon and Coahuila, seem to mark the southwestern limit of the range assignable to _taylori_. On December 27, 1958, a specimen, KU 81552, was obtained 3 mi. N Bowie, Montague County, Texas. This record station extends the known range of _B. taylori_ 65 miles northward from the previous northernmost locality, listed by Hunsaker, Raun, and Swindells (1959:447). Two specimens, KU 81553 and 81554, were collected by the author 2 mi. NE Cedar Hill, Dallas County, Texas, on October 31, 1958. These two specimens, plus the single specimen from Bowie County are all paler with more buffy bellies than either _B. t. taylori_ or _B. t. subater_. They may represent an incipient subspecies. I tentatively assign them to _B. t. taylori_ because of the pale rather than dark (like _B. t. subater_) pelage. Additional specimens are needed from these areas and from the hiatus between the ranges of _B. t. taylori_ and _B. t. subater_ the better to understand the manner in which these two subspecies intergrade.
