Correlations. — The most obvious correlation appears to be the phenora- 

 enon of a high number of subcaudals (i. e., the male sex) and a low scale 

 formula. 



A double loreal appears to accompany a low scale formula also, and a 

 triple nasal very rarely appears in the absence of the double loreal. No 

 other correlations are evident. 



Conclusions. — These are chiefly conspicuous by their absence, but the 

 young appear to inherit from the mother: (a) the decided abnormality 

 of a double loreal; (6) the reducing of 19 to 17 by dropping the third 

 row. The averages of ventrals, sub-caudals, and color bands are quite 

 close to the mother's formula. They show a smaller number of dorsal 

 scale rows, and a smaller labial formula.
