Mammals; Mammals; Trees; Trees; Natural history; Natural history. -*siir Fig. 45.—ScinEDS eufiven- TER TEXTANUS. DORSAL VIEW OF SKULL. FOKT Clark, Texas. (Cat. No. 12710, Amer. Mus. Nat. Hist.) ears, feet, inner surface of limbs, and all of under surface of body orange-buff. Tail grizzled above, in the median area, with broad, lateral, subterminal bands of black and broad yellowish Avliite tips to the hairs; under side of tail tricolored, orange-buff mesially, this bor- dered successively by black and yellowish white. The naked under surfaces of the feet are pur- plish black. Length, 475 mm.; tail to end of ^-ertebrse, 225; tail to' end of hairs, 300; ear from crown, 18; ear from notch, 30; head, 67; hind foot, 66. Cranial characters.—This species has but one premolar on each side, above. Skull in texianus (fig. 45) low, with a weak rostrum; superior profile flattened in the frontal region, sharply declining posteriorly; postorbital processes of medium length and sharply deflected; audital bullae, small; incisive foramen, long and nar- row ; interpterygoid fossa, long, nearly equal- ing the length of the upper lateral tooth-row. Greatest length of skull, 61 mm.; greatest breadth, 35. Remarks.—The color of the under surface fades with wear and exposure until it becomes nearly white, and its intensity is also subject to some individ- ual variation. On the whole, the form is re- markably uniform. No black individuals were seen or heard of, though the fox squir- rel of northeastern Texas is frequently mel- anistic. Dr. J. A. Allen" mentions a speci- men from Rockport, Aransas County, Texas, " not appreciably different from speci- mens from the type locality (San Pedro or Devils River) of Baird's Sciurus limitis (^texianus), recently received from Dr. E. A.
