Variation. — The t3'pe .speeinicii above de.scribed is rather extreme 

 in some points of the scutellation of the head, namely in the wide 

 contact of the supraocular semicircles, which probably are more com- 

 monly separated by a single row of scales, and in the single row sepa- 

 rating the occipital shield from the semicircles, there being- usually two 

 rows. No. 27290 is rather extreme in the latter respect, the occipital 

 being broken up so that there appears to be three such rows (fig. 121.) 



The degree of distinctness of the keels or wrinkles on the head 

 scales is greatly variable, as in some of the younger specimens these 

 scales are smooth or nearl}' so.
