I'reociilar and postocular, supratjmpauic, and superciliarj" ridges well <]eveloped, the last making a very open angle with that of the cautlius 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 opposite lower edge of tympanum. Skin everywhere rigidly rugose, subspinous on the tarsus. The joints of the extremities are pale and appear swollen. Fingers slender; first shorter than second, which equals the third. One metacarpal tubercle only.
