DESCR. The head is depressed, elongated, narrowing anteriorly. 

 Its upper surface is smooth, flattened from the occipital region to the 

 nostrils, hence, declivous towards the margin of the jaw; its sides are 

 sloping, and the phrenic region is depressed. The nostrils, oblong in 

 shape, are obliquely situated near the upper part of the snout, at the 

 culminating point of its declivity, and twice as distant from the an- 

 terior rim of the eye than the margin of the upper jaw. The eyes 

 are proportionally large, subelliptical in shape ; their longitudinal 

 diameter being equal to the rhinic distance from their anterior margin 

 to the nostrils. The interocular space is equal to the ocular diameter. 

 The tympanum is quite conspicuous, subcircular ; its diameter being 

 greater than the radius of the eye ; it is situated immediately above 

 and posteriorly to the angle of the mouth, at a little distance 

 from the orbit. The mouth, itself, is deeply cleft ; the tongue is elon- 

 gated, subpyriform, narrowest anteriorly, and free upon its posterior 

 half; laterally, it is but slightly so. The inner nostrils are quite 

 large, transversly elliptical, situated towards the periphery of the pal- 

 atine roof. The vomerine teeth are disposed upon two oblong groups, 

 widely separated from each other and situated obliquely behind the
