SALIENTIA. 



Salientia Laurenti {Syn. Rept., p. 24, 1768) contained the genera 

 Rana, Pipa, Hyla and Bufo, as well as Proteus, which seems to have 

 been founded on a tadpole of Rana. It is therefore equivalent to and 

 much older than Ecaudata Dumeril (1806). Anura, attributed by 

 Cope to Dumeril, has no standing, as that author used only "anoures." 



RANID^. 



Rana Linn. (Syst. Nat., Ed. X, p. 354, 1758). 



Type Rana temporaria Linn. By designation of Gray (Ann. of 

 Philos., 1825, p. 214). 



ENGYSTOMATID^E. 



Engystoma Fitzinger (Neue Class Kept., p. 65, 1826). 



Rana oralis Schneider is the only one of Fitzinger's species retained 

 in Engystoma by Dumeril and Bibron {Erp. Gen., 8, p. 741, 1841) and 

 is consequently the type. 



Hypopachus Kerferstein (Gottingen Nachrichten, 1867, p. 352). 



]\Ionotype Hypopachus Seebachii Kerf. (= H. variolosum Cope). 

 OYSTIGNATHID^. 



Lithodytes Fitzinger (Syst. Rept., p. 31, 1843). 



Type Hylodes lineatus D. and B. By original designation. 



Syrrophus Cope (Amer. Naturalist, 1878, p. 253). 



Monotype Syrrhophus marnockii Cope. 

 HYLID^. 



Chorophilus Baird (Froc. Acad. Nat. Sci. Phila., 1854, p. 60). 



Monotype Cystignathus nigritus Holb. 



Acris Dum. and Bib. (Erp. Gen., 8, p. 506, 1841). 



Type Hylodes gryllus DeKay. By designation of Baird (Proc. Acad. 

 Nat. Sci. Phila., 1854, p. 59). 



Hyla Laurenti (Syst. Rept., p. 32, 1768).

Monotype Smilisca daulinia Cope (= Hyla haudinii Dum. and Bib.),

Type by tautonomy Bufo vulgaris Laur. ( = Rana bufo Linn.).
