 reaching the apex of the casque ; the distance between the corner of the 

 mouth and the apex of the casque equals that between the former and 

 the tip of the snout ; lateral crest surrounding the casque posteriorly, 

 tubercular ; superciliary crest considerably raised, rounded and tuber- 

 cular ; two compressed, scaly rostral appendages, or horns, diverging 

 anteriorly, each with three serrated ridges of large pointed scales, one 

 above and one lateral, the latter in direct continuation of the super- 

 ciliary ridge and canthus rostralis ; top of head symmetrically covered 

 with numerous irregular scales and granules of various sizes ; no trace 

 of occipital lobes ; body granular with two or three indefinite rows of 

 irregular flat tubercles on each side of the upper half between the lat- 

 eral "pavement" series and the median dorsal line; no tubercles, or 

 spines, on the latter, which is covered with minute granules ; no gular 

 nor ventral crests ; no tarsal process ; tail longer than body and head 

 including horns. Color (in alcohol) j)lumbeous, with indications of a 

 whitish spot below and behind the eye and continued posteriorly in an 

 indistinct and interrupted stripe over the shoulders ; throat pale. 



In addition to the type specimen, there are two more specimens from 

 the same locality, agreeing in all essential points with the above de- 

 scription. 



* This is the spelling adopted by the founder of the genus, and consequently the 

 one to be employed to the exclusion of the more commonly accepted ChaviwJeon.
