Common in all parts of the island but not as abundant as 

 Cucmidophorns anihcnsis. 



Ten specimens are typical in scalation and show no tendency 

 toward the subspecies divisus. The ground color is more uni- 

 form and paler than in mainland series, black spots being ab- 

 sent or very few in number. 



Cncmidophonis uuirinus (Laurenti). — Curacao (Schaarlo; 

 Sint Willebrordus ; Ronde Klip): Bonaire (Seroe Grandi, 

 near Playa Makosji; Seroe Grandi, ^lA km. northeast of Kral- 

 endijk; Santa Barbara; Pos Frances; Seroe Wassau) : Klein- 

 Bonaire : Klein-Curacao. Listed from Curacao by Van Lidth 

 de Jeude, Meek, and Cope, and from Bonaire by Meek. Cope's 

 C. murinus from Aruba is probably C. aruhcnsis. 



Abundant, according to Baker's notes. 



Cncinidoplwrus aruhcnsis (Van Lidth de Jeude). — Aruba 

 (Oranjestad; Rooi Lamoenchi ; Boedoei; Campo West Punt; 

 near Perkietenboseh). 



Described from Arul)a by Van de Lidth de Jeude. 



Abundant in all localities. 



This is Meek's Cncniidophorus nigricolor, from Aruba ; and 

 it is probably Cope's C. murinus from the same island. Al- 

 though resembling C. murinus in coloration, C. aruhcnsis is ap- 

 parently most closely related to C. Icmniscatus. It has eight 

 rows of ventrals, as pointed out by Van Lidth de Jeude. and 

 the subcaudal scales at the base of the tail are keeled as in 

 C I. Icmniscatus and C. I. gaigci. It differs from C. Icmnis- 

 catus in having smaller brachial and collar scales, and in color- 

 ation. The pale spots are much larger and fewer in numl)er 

 in C. aruhcnsis and the pale lines disappear, or are only faint- 

 ly indicated, in old s])ccimens. C. nigricolor from Los Roques 

 is easily distins/uishcd from C. aruhcnsis by the color, by the
