with the frontal ; posterior border of the interparietal in contact 
with the nuchals, of which there are one or two pairs; seventh or 
eighth upper labial the largest; ear-opening about as large as a 
dorsal scale, with two or three more or less distinct obtuse lobules ; 
two azygos postmentals. 28 to 32 scales round the body, subequal,
