Stejneger — The Amphibian Generic Name Engi/stoma. 167 



As shown above Engysioma becomes a synonym of Breviceps, 

 and with it must also disappear the family name Engystomidse 

 (and Engystomatidse). The name Brevicipitidse , created by 

 Cope, in 1867, for a smaller group becomes available, however, 

 and may l)e used. The more familiar Phryniscidse is unavail- 

 able since it has been shown that the genus Phryniscus belongs 

 to the Bufonidie.
