Femorum facie posteriori vel omnino granulosa, vel squamis parvis 

 imbricatis, prope basim caudae, tecta. Corpore vittis lonyitudinalibm 

 varii colons, quibus macularum series permiscuntur, notato ; interdum 

 tamen transverse fasciato.

 smooth, generally entire posteriorly. Posterior aspect of thighs

OBSERV. Differs from Ptycliodeira, its nearest relative, by smooth 

 temporal scales, and the presence, on the sides of the neck, of 

 granules, instead of small scales, such as are observed on the body. 

 The folds or wrinkles are also more conspicuously developed in Rhyti- 

 dodeira than in Ptycliodeira.
