The following specimens, born in the Zoological Gardens, London, 

 have been stated to be hybrids between Epicrates aiu/ulifer and 

 Chilahotlirus inornatus (Sclater, Proc. Zool. Soc. 1878, p. 789). 

 But as they do not differ from E. strlatus, and as I entertain 

 doubts concerning the correct determination of the parents (which 

 I have not been able to trace), I feel justified in referring them to 

 this species.
