The picture is less clear as regards bats from southeastern Texas (one specimen each from Colorado and Travis counties, and four specimens from Harris County). Five of the specimens have skulls (the Travis County specimen is a skin only) and of these, four are clearly assignable, on the basis of size and shape of the skull, to _intermedius_. The fifth skull (specimen from Colorado County) is intermediate in size between _floridanus_ and _intermedius_ and on that basis alone could be assigned with equal propriety to either. All these specimens from Texas more closely resemble _floridanus_ than _intermedius_ in external size (forearms: 49.2, 49.6, 50.7, 49.9 (approximate), 49.6, 49.1). The pale yellowish-gray upper parts of the four adults, seemingly resulting from a dilution of the brownish color found in _floridanus_, differ from the color of typical specimens of both _intermedius_ and _floridanus_, but the average is nearer that of _floridanus_ than that of _intermedius_. Color of pre-adult pelage in the one July-taken young of the year resembles the color of adults. An August-taken young of the year is in process of acquiring the adult pelage but the hairs have not reached their full growth; it is pale yellowish but not so grayish as the other specimens. All characters considered, the specimens from eastern Texas resemble _floridanus_ more than they do _intermedius_, and so are provisionally assigned to _floridanus_ (as was done by Taylor and Davis, 1947:19; Eads, _et al._, 1956:440; and, Davis, 1960:59). Additional material from southeastern Texas is needed. It will be remembered that the type locality of _intermedius_ is in the Rio Grande Valley; all specimens seen, in the study here reported on, from the Texas side of the valley are unquestionably referable to that subspecies. Intergradation, then, occurs between _L. intermedius_ and _L. floridanus_ in some degree in southern Louisiana and in more marked degree in southeastern Texas. Specimens from the area of intergradation vary more individually in many features than do specimens from other areas. In general the intergrades tend to resemble _floridanus_ in small size externally and _intermedius_ in large size of skull. The specimens from southeastern Texas differ from typical specimens of both subspecies in color, being pale yellowish-gray (instead of yellowish to yellowish-orange as in _intermedius_ or yellowish brown to brownish-gray as in _floridanus_), and this difference is shared to some extent with animals from Louisiana, the latter being somewhat intermediate between bats from Texas and those from Florida and Georgia, although nearer those from Florida and Georgia.
