Form dieses Subgenus als Rhinchenycteris [Choeronycteris] peruana aufge- 
führt; bei der Untersuchung der Handflügler des Museums in Berlin fanden wir 
eine als Choeronycteris opercularis bezeichnete verschiedene Species aus Mejico

das Subgenus die bezeichnende Benennung Choeronyeteris."  (Tscnupnr.)

Caballos Fés. Pampa Argentina, 15, 1875. 
Species: Equus neogeus Lund, and FE. principalis Lund, from Brazil. **Como la 
figura particular del hueso de la nariz del caballo fósil no dejaba ninguna 
duda, que este animal debe formar un género aparte de los caballos vivos, le 
había dado el nuevo apelativo Rhinippus, derivado de la figura particular de 
sunariz. Mís tarde he visto que ya D. Ric. Owen [1869] había fundado en 
los eaballos fósiles de la pampa . . . un género aparte, nombrándole Hippi- 
dium . . . no puede.conservarse mi nombre por la ley de la ancianidad del 
otro."  (BunMErsTER.)
