166 Stejneger — The Amphibian Generic Name Engystoma. 



In the face of Fitzinger's original designation this perversion 

 can not be accepted under the International Rules of Zoological 

 Nomenclature and it becomes necessary to select a name for 

 the genus which now erroneously is called Engi/stoma. The two 

 earliest names, as stated above, are preoccupied. The next 

 available term is Fitzinger's Gastrophryne based on Dumeril and 

 Bibron's Engystoma rugosiim, which has been considered a 

 synonym of our E. curolinense. 



The synonymy of the genus will tlien stand as follows: 



Qastrophryne Fitziiiger. 



1828. Microps Wagler, Isis, 1828, p. 744 (monotype, Microps 



unicolor = Rana avails Schneider) (not of Meg., 



1823). 

 1838. Ste nocephal us Tschudi, Classif. Batr., p. 86 (same type) 



(not of Latr., 1825). 

 1811. Engystoma Dumeril and Bibron, Erpet. Gen., vol. 8, 



p. 738 (same type by designation) (not of 



Fitzinger, 1826). 

 1843. Gastrophryne Fitzinger, Syst. Rept., p. 33 (type by 



original designation, Engystoma rugosum Dum. 



Bibr.).
