Re- garded by Glass and Baker (1968) as nomen dubium. Distribution in Colorado.—Locally in suit- able habitat on the eastern plains and along the foothills of the Front Range (Fig. 23). Comparison.—From M. I. melanorhinus, the subspecies of western Colorado, M. I. ciliolabrum differs in paler dorsal and ventral color, the underparts being only slightly or not at all tinged with buff. Measurements.—External measurements of a male and a female from Larimer County and females from El Paso and Boulder counties are, respectively: 85, 86, 77, 76; 38, 35, 39, 35; 8, 7, 7, 8; 14, 15, —, 12; , , , Selected cranial measurements are presented in table 3. Remarks.—Thomas Say (in James, 1823) proposed the name Vespertilio subulatus for a bat collected by the expedition of Stephen Long near the confluence of Apishapa Creek and the Arkansas River, in what is now Otero County, Colorado. Whether the specimen de- scribed by Say actually was preserved is not known; at any rate, a holotype no longer exists. In the absence of a holotype, the name subulatus has been variously misapplied, par- ticularly to the species now known as Myotis keeni (see Miller and Allen, 1928:166). Glass and Baker (1968—also see Glass and Baker, 1965) reviewed the history of the name subulatus, corrected misconceptions about the type locality, and suggested that the original descript
