OBSERV. The sides of the neck are wrinkled and granular, as in 

 Rhytidoddra, but there is, in addition, a vertico-oblique fold in ad- 

 vance of the shoulder, and which is wanting in the latter. The 

 dorsal scales are smaller also, but slightly carinated, the keels not pro- 

 truding beyond the posterior edge of the scales, which is rounded, in- 

 stead of being acuminated.
