and are nearly parallel. The interorbital space is considerably nar- 

 rower than the width of a superior eyelid. The tympanic disk is round 

 and is a little larger than the eye. The vomerine teeth form transverse 

 patches entirely between the choanaBj that is, their posterior edges do 

 not reach the line connecting the posterior borders of the choause. 

 The ostia«pharyngea are considerably smaller thy^n the choanse. 



The first is considerably longer than the second finger and equals 

 the fourth. 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 cuneiform tubercle is small, 

 but is prominent, and has an acute edge. No external tubercle. 



Between the dorsolateral dermal folds there are, on the doi-sal region, 

 four thin dorsal plicse. CJn the pelvic region the external two are ru- 

 dimental, while the middle pair are distinct, and near together or on 

 each side of the urostyle. 



In this specimen the dorsal spots are suboval, are rather large, aud 

 are not yellow bordered. The dorsolateral fold is yellowish-brown, and 

 there is a series of brown spots of irregular size, but smaller than the 

 dorsals, just exterior to it. Below these the sides become yellowish, like 

 the belly, and have small bro wu spots. A dark- brown baud extends from 

 the nostril to the orbit, and is continued from the latter round the poste- 

 rior border of the tympanic disk. A similar band extends from the infe-

 brown, with small yellowish spots, aud the superior brown is bounded 

 above by a narrow yellow line, which commences below the front of the 

 orbit aud continues below the tympanic drum to above the posterior 

 edge of the humerus. Below, everywhere light yellowish, unspotted. 

 Posterior faces of femora brown, with paler coarse vermiculations.
