semilineatus off from most other Hispaniolan Leiocephali. The pat- 

 tern of the young is retained through the adult stages and is the 

 same in male and female. 



The species does not seem to be widespread in Haiti, since it has 

 been secured at only two places up to the present. 



Sclm^iidt ' maintains that semilineatus agrees with melanochlorus 

 rather than with personatus in having the same number of shields 

 between the rostral and the supraorbital ring, owing to his mistaken 

 understanding as to the actual number of such shields in the thiee 

 species named. As a matter of fact, both semilineatus and personatus 

 have three shields, while melanochlorus has four. Furthermore, the 

 last-named species belongs to that group having a lateral fold and 

 therefore is very sharply distinct from the other two.
