In the extension of this light space backwards it becomes lighter, until from beneath the eye it passes below the postocular band to the base of the fore-arm as a grayish-white vitta, usually about half as broad as the one above- it. Sometimes a series of scattered rounded spots may be traced along the side in continuance of the dark postocular vitta. The extremities above are transversely and narrowly but indistinctly barred with darker. The rest of the legs is uniformly flesh color (thighs posteriorly dusky) except a few aggregated pustules below and about the anus, which are white (no marking on the inner faces of limbs); this is seen In other species, but. is very distinct here. The immediate border of the anas is brown; beneath, white; edge of gular sac, black. In some specimens, especially those from Fort Tejon, the prevalent color above is ash-gray, with an elongated blotch along each side of the back for its whole length, and one or two others on each side of those dorsal blotches are nearly wanting. Sometimes the exterior edges of the tibia and feet (when flexed), are blotched with browu. This variety resembles H. scjuirella, bat the head is less depressed ; the colors are darker; the dorsal blotches are larger,and elongated longitudinally in two or three series; the white margin to the much darker postocular vitta is broader; the body is stouter, and usaally more or less granulated. The toes are less deeply webbed. The figure of this species in volume ten of the Pacific Eailroad Sur- veys represents an interdigital membrane anteriorly, which does not ex- ist, and that of the posterior limb is too 1 2 4 6 11^ Via. 89.
