Callosciurus phayrei

The body is slightly larger than the red-bellied squirrel. The back, snout, behind the ears, top of the head, and sides of the neck are grayish brown. The abdomen is orange-yellow, and there is usually a faint black stripe on each side of the abdomen. The tail is long, the tips of the tail hairs are black, and the ventral surface of the tail is yellow. The limbs are yellow-white or light orange-yellow (bounded by the wrist joint). The salient features of the skull morphology are: the front section of the nasal bone is significantly curved downward, the width of the interorbital part is significantly larger than that of other species of squirrels in the genus Squirrel genus, and the postorbital process and zygomatic arch are relatively developed.
