 By G. A. BouLENGEK, F.Z.S. 



[Eeceived January 24, 1887.] 



A small collection of Pteptiles and Batrachians was formed by Mr. 

 W. L. Sclater during his recent visit to Maccasseema (on the Pome- 

 roon River) in British Guiana, and presented to the Natural History 

 Museum. Small as the collection is, and from a comparatively well- 

 explored district, it nevertheless contains a novelty, the small Lizard 

 described below. The other species of which specimens were 

 obtained are the following : — • 



Lizards : Thecadaetijlus rapicauda, Houtt. ; Anolis punctatus, 

 Daud.; OphryoessasvpercUiosa,'L.; Uraniscodun umbra,!,.; Cophias 

 Jiavescens, Bonn. ; Amphisbcena fuliginosa, L. 



Gonatodes annularis.
