Intac, Ecuador. 



Prof. Yaillaut has recently pointed out that the late Prof. 

 Peters was mistaken in identifying the type specimen of C bivit- 

 tata, which he had an opportunity of examining, with IchthyopMs 

 ghUinosns, and that the genus Ehiriatretna is in every respect 

 identical with Eincrlonups, established by me in 1883, at a time 

 when 1 had no reason to question the correctness of Peters's iden- 

 tification. It is now to me even a matter of doubt whether the 

 two species mentioned above are really distinct, considering the 

 amount of variation in the number of folds in IcJithyophis.
