those of the vertebral region larger than those on the sides : 

 ventral scales larger than the dorsals, smooth. Tail compress- 

 ed, with serrated upper edge (regenerated). About 26 lam- 

 ellae under the second and third phalanges of the fourth toe. 

 Gular pouch rather large. Brown above with black crossbars 

 bordered with yellow, and somewhat interrupted on the flanks ; 

 ventral surfaces white, the sides of the abdominal region with 

 faint spots, the chin mottled with dark brown, the gular pouch 

 uniformly white (in alcohol). 



Length of head and body 66.5 mm. 



Length of head 19 mm. 



Length of hind leg 50 mm. 



Notes on Paratypes : The supraorbital semicircles in nine- 

 teen specimens are entirely separated in six, in contact by one 

 pair in ten and by two pairs in three. The enlarged supra- 

 oculars are smooth in all specimens, and the occipital is sepa- 

 rated from the supraorbitals by small scales in two specimens. 



The localities are as follows: Bonaire (Santa Barbara; 

 IMontagne ; Punta Blanco; Seroe ^^'assau; Seroe Grandi) : 

 Klcin-Bonaire. Usually (found upon trees. ) Also recorded 

 from Bonaire by Meek under the name A. alligator. (Com- 

 mon everywhere on trees and cliffs. ' 



Remarks: As is well known, anoles from a number of is- 

 lands in the Carribean Sea have been referred to Anolis alli- 

 gator. Barbour (1914, p. 281) has asserted that the Martin- 

 ique form is distinct from the one on Trinidad, an assertion 

 that has been supported by a study of specimens from both 

 localities. A well marked difference is to be found in the size 

 of the scales about the occipital plate. In a series of specimens 

 these scales are as large as the scales of the forehead in those
