Dcs Moines, Iowa, |; 6 and 7, f. Brownish above. The median region of bead and body above bright green; a dark triangle between the eyes. Three oblique blotches on the sides, nearly equidistant: the first behind the eye, the last on the flanks and running up on the back; all usually margined with lighter, a narrow white line from the eye to arm. Beneath yellowish-white. Inferior face of thigh plain. Tibia a little more than half the length of the body. Foot rather smaller. Head rather obtuse, scarcely longer than broad. Web of hind foot extending to the penultimate articula- tion of the fourth toe. This subspecies is characterized by a rather long, narrow head, with the eyes farther back than usual. There is no constriction for the neck, the outline tapering towards the snout from about the middle of the body. The limbs are very muscular, and considerably developed. The eyes are large and prominent; their anterior edges decidedly be- hind the middle of the commissure, and their posterior barely anterior to the angle of the mouth; hence the snout is considerably produced. The nostrils are minute, situated on the canthus rostralis, rather nearer the tip of the snout than the eye, and separated by a distance less than one-third the width of the rami. The tympanum is small, not very dis- tinct, about half the diameter of the eye, and placed just above the ric- tus. The head is almost as long as wide, especially in large specimens. The t
