deep, and constituting the inferior rim of the orbit ; the sixth and 

 seventh subrhomboid, and as large as the fifth. The symphyseal, 

 somewhat smaller than the rostral, is hemidiscoid. The lower labials, 

 six on either side, are unequal ; the two anterior small and quadran- 

 gular ; the third, fourth, and fifth elongated and larger ; the seventh 

 diminutive or exiguous, hardly visible when the mouth is closed. A 

 very large, odd mental shield occupies the transverse area of the chin, 

 between the anterior two labials. It is followed by four pairs ; the 

 anterior pair largest, and contiguous upon the middle line of the chin; 

 the remaining diminishing in size, and diverging posteriorly. The 

 auricular aperture is large, subelliptical, provided anteriorly with three 

 or four projecting scales, giving that edge a denticulated appearance. 

 The tympanum is rather deeply seated. 



The scales are perfectly smooth and shining : twenty-six longitu- 

 dinal series may be counted as surrounding the body : four dorsal 

 series, the two middle ones considerably larger ; fourteen lateral series 

 (seven on each side), smaller, and eight abdominal series, somewhat 

 larger than on the sides. The two middle preanal scales are consider- 

 ably developed. The tail is tapering and pointed, much longer than 

 the body and head combined ; it is protected by larger scales than the 

 back and belly, and on the middle inferior row, they are much more 

 developed still, being transversely elongated, simulating true scutellae. 

 The fingers and toes are very slender, compressed and unequal, espe- 

 cially the toes, the fourth of which is quite long. 



We pass over the coloration, which is very well described by our 

 predecessors.
