The heel reaches eight or ten millimeters beyond the end of the nose. The palmation is rather narrow and leaves three phalan- ges of the fourth toe free. The internal eiineirorm tubercle is small, but is prominent, and has an aiaite edge. No external tubercle. Between thedorsttlateral dermal folds there ;*: thedursal region, four thin dorsal plica'. i)n the pelvi(! region the external two are rn dimental, while the middle pair are distinct, and near togetiier or on each side of the urostyle. In this specimen the dorsal spots are suboval, are rather large, and are not yellow bordered. The dorsolateral fold is yellowisli-browu, and there is a series of brown spots of irregular size, but smaller than the dorsals, just exterior to it. JJelow these the sides becunne yellowish, like the belly,and have small brown spots. Adark-brown band extends from the nostril to the orbit, and is (!ontinued from the latter round the poste- rior border of the tympanic disk. A similar baud extends from the infe-.
