Head broad; muzzle prominent, conic. Cranium stronjfly rid}?ed. Preocular and postocular, sui)ratympanic, and superciliary ridges well developed, tlie last making a very open angle with that of the canthus rostralis, and sending off posteriorly a parietal, which first converges toward that opposite, and then runs transversely on the occiput to meet it, failing in this by a very slight interval. A small nuchal pit. Tympanum in contact with postorbital ridge, only one-fourth the size of the orbit. Tongue small, narrow, half free; a strong symphyseal tubercle fitting a premaxillary pit. Parotoids large, short, descending on sides to oi)posite lower edge of tympanum. Skin everywhere rigidly rugose, subspinous on the tarsus. The joints of the extremities are ])ale and appear swollen. Fingers slender; first shorter than second, which equals the third. One metacarpal tubercle only. Toes short, one third webbed ; two acute metatarsal tubercles, the internal large, incurved, like a flattened spur, yellow, brown tipped. Length of head and body, 10 lines; of hinder extremity, 12 lines. The head above is dusky, with a yellowish central longitudinal line; the superciliary ridges are gray, with a white mark in the center. On each side of this longitudinal line is an oblong black si)Ot, extending from it to include most of the posterior part of the orbit of the eye; a small part only of the orbit in front of this is light colored ; the upper jaw is light Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of t
