r.y all antliors the j;-enns Amphinma liatl been incliuletl in the same 

 family ilivision with I'rottintipsis aiitl iMefialobatrachns until 18(5(5. At 

 that time the writer pi'opt).setl to separate it fnun the latter genera as 

 the type of a family .Vmpliiniiiiihe, wiiilc the ttther .uenera were platsed 

 in ant)ther family with the iiamt^ I'rotoiiopsithe. This course has not 

 been followed by later writers; in the catalogue of the Uritish Museum 

 by Dr. i'>oulenjii'r (ISSL*), for instance, the three j-enera are intihitled in 

 one family, the Ampliiumida'. 



The reasons for keepin,n the Amphiumiila' tlistinet from the Protonop- 

 sida' were statetl to be the Ibllowing:*
