Baiomys taylori (O. Thomas, 1887) |
Description
From Eshelman & Cameron (1987): "Juveniles are uniformly gray above and lighter below (Packard, 1960). The dorsal pelage of adults varies from reddish brown, through gray to almost black above and white to creamy buff or gray below. The tail is covered with short hairs. Color of tail differs among subspecies and may be uniformly gray or bicolored (lighter ventrally)."
From Schmidly & Bradley (2016): "Smallest of the cricetid mice in Texas, with the exception of two harvest mice, Reithrodontomys humulis and R. montanus, both of which differ in having grooved upper incisors and longer tails. Upperparts grizzled grayish in adults, blackish in juveniles; underparts smoke gray; tail about three times as long as hind foot, sparsely haired, and decidedly shorter than head and body. They have a strong, musky odor similar to that of house mice, Mus musculus."
