Form much as in E. quinquelineatHs, tlie tail a little thicker, the muz- 

 zle more narrow and elongate. The anterior extremity extended for-

 beyond the appressed elbow, but not to the axilla. Rostral plate as 

 high as broad, less depressed than in U. quinqueUneatiis ; nasal small; 

 nasofrenal smaller, trapezoid; anterior frenal as long as high. Eight

 Supranasals large, considerably in contact; internasal transverse, sub - 

 truncate posteriorly; frontomisals as long or more frei[uently longer 

 than broad, extensively in contact. Frontal elongate, in front obtuse, 

 posteriorly acute angled. Inferior labials, seven; symphyseal deeper 

 than in E. quinquelineatHs; one large seven-sided mental in contact 

 with two labials on each side, two infralabials jtosterioiiy, and the
