Barbour — Amphibians and Reptiles from Tobago. 223 



served, is the only one of the species which he saw upon the island. It 

 has not been previously recorded from Tobago. 



Tupinambis nigropunctatus Spix. 



A single adult example from Milford Bay collected by Dr. H. L. Clark. 

 This lizard is a real surprise. It is noteworthy to find that this large, 

 voracious terrestrial lizard has apparently never before been taken upon 

 Tobago. 



Atneiva tobagana (Cope). 



When discussing this species in our Revision of the Genus Arneiva 

 (Bull. M. C. Z., 59, 1915, p. 458), Mr. Noble and I had no specimens 

 before us for examination. Doctor Clark's material secured at Milford 

 Bay, southwestern Tobago, however, provides a really fine series of this 

 distinct form. Young, half grown and adults are represented. 



Cnemidophorus lemniscatus (Daudin). 



A finely preserved large series from Milford Bay. It is not strange 

 that this species is to be found upon Tobago as it occurs upon Trinidad 

 and the Venezuelan Leeward Islands as well as widely spread upon the 

 mainland. The males and females of the suite in hand show the remark- 

 able dichromatism which is so conspicuous and so stable. 



Mabuya aenea Gray. 



Two seines which may be referred to this species provisionally, came 

 here with the Broadway suite. Garman has considered the slippery-backs 

 from St. Vincent, Grenada and Trinidad distinct from M. aurata 

 (Schneider) of the mainland. The Tobago examples may well rest thus 

 also until accumulated material makes possible a final working-out of 

 their status. This seine appears also to be new to Tobago. 



Constrictor constrictor (Linne). 



The dried skin of a large adult was among the material secured from 

 Mr. Broadway of Scarborough. Specimens from Tobago are reported by 

 Boulenger to be in the British Museum. 



Epicrates cenchria (Linne). 



Two boas which evidently belong to some race of this species are not 

 provided with a subspecific name as material is not at hand for a satis- 

 factory study of the species. Both of the examples before me came from 

 Milford Bay. I can not find that this boa has been previously noted 

 upon Tobago. 



Spilotes pullatus (Linne). 



A large serpent to which this name may well be applied provisionally 

 was among those sent by Mr. Broadway. It had been known from 

 Trinidad but apparently not from Tobago.
