Ameiva undulata quadrilineata (Hallowell). 



Two, 170 and 182 mm. long. These represent Ameiva gabbiana 

 Cope, merged in the synonymy of the present species by Dr. Bou- 

 lenger. They vary slightly. The single enlarged rounded preanal 

 plate is present. Scales in middle of throat but slightly enlarged, 

 and collar with an enlarged plate each side of median line. Humeral 

 scutes in one row. Great variation is also seen in the scutes on top 

 of the head. In one example the frontonasal is not in contact with 

 the posteronasal, as a small scale intervenes. Scales in the supra- 

 orbital semicircles and at occiput quite variable. Some blackish 

 dots on throat.

 Caribbean, during July, in which case the locality is given.
