100 REPTILES. 



M. Bibron observes that the genus Siguana (Otophis, Fitz.) 

 only depends on the accident of the ear being sometimes more ex- 

 posed. I have unfortunately not the opportunity of verifying the 

 accuracy of this remark. I have placed Dorfia in this genus, un- 

 til 1 can again examine the specimen.
