ridges bordering a very shallow frontal hollow; head scales distmctly 

 keeled and medium sized : five scales in a row between the supranasals ; 

 supraocular semicircles very narrowly in contact (in this specimen) 

 but mostly separated by a single row of scales; occipital large, about 

 twice the size of the ear opening, separated from the supraorbital 

 semicircle by two flat scales; supraocular disk composed of two very 

 large, keeled scales accompanied by four or five smaller ones, the former 

 separated only partially from the supraorbital semicircles by a single 

 incomplete row of small scales, the latter separated from the super- 

 ciliaries by about three rows of minute, almost granular scales; a series 

 of three or four enlarged and elongated scales bordering the anterior 

 inner portion of the first superciliary, followed by granular scales con- 

 tinued as far as the supraocular disk; can thus rostralis projecting over
