62560) were taken at Duverge on October 2, 1919, the first two fe- 

 males, the last a male measuring 1,055 mm. in length. A specimen 

 (No. 63112) was secured off Petit Gonaive Island on July 10, 1920. 

 A very young specimen from Tortuga captured February 1, 1917, 

 measures only 112 mm. from snout to vent. 



I have noticed very great variation in the arrangement of the 

 scales on the snout, and I do not think that specific characters can 

 be found there. The conditions in each specimen are given briefly 

 as follows : 



No. 59455. — Nasals and rostral narrowl}^ in contact on the right 

 side, separated by small scales on the left side; frontal and prefron- 

 tals separated by two rows of small scales. 



No. 60599. — Nasals and rostral separated by medium-sized scales; 

 frontal and prefrontals separated on the right side by numerous 

 small granules, on the left side by two rows of small scales. 



No. 60600. — Nasals and rostral separated by a row of medium-sized 

 scales ; frontal and prefrontals in close contact. 



No. 60601. — Nasals and rostral separated by one row of medium- 

 sized scales; frontal and prefrontals in contact on the right side, 

 separated by a narrow strap-like scale on the left side. 



No. 62588. — Nasals and rostral in contact rather broadly on both 

 sides; frontal and prefrontals separated by one row of very narrow 

 scales. 



No. 62559. — Nasals and rostral separated by a row of rectangular 

 medium-sized scales; frontal and prefrontal separated by a row of 

 moderate-sized polygonal scales and an additional row of very nar- 

 row strap-like scales which encircle the base of the frontal horn. 



No. 62560. — Nasals and rostral in contact, rather broadly so on 

 the left side, narrowly on the right side; frontal and prefrontals in 

 close contact. 



No. 63112. — Nasals and rostral separated on the right side by 

 medium-sized scales, on the left side by a very narrow scale ; frontal 

 and prefrontals Avidely separated by two rows of polygonal scales. 



No. 65139. — Nasals and rostral narrowly in contact on the right 

 side, separated by a row of very small scales on the left side ; frontal 

 and prefrontals separated by a row of very narrow scales. 



LEIOCEPHALUS MELANOCHLORUS Cope 



One specimen (U.S.N.M., No. 60621) from Jeremie, Haiti, col- 

 lected November 22, 1917. 



LEIOCEPHALUS SCHREIBERSII (Gravenhorst) 



Thirteen specimens (U.S.N.M., Nos. 59442-59454) from Tortuga 

 Island collected on January 30, 1917. These specimens agree well 

 with Haitian examples in our collection.
