This genus shows its nearest aflines t» be Callida and allied genera 

 of the Eugystomida' in the wide separation of the lobes of the liver for 

 the aeeommodation of the pericardial sac and its contents, and by the 

 posterior position of the heart. In the latter point it exceeds all other 

 genera; the heart i.s of relatively large size, and oecui)ies nearly the 

 median portion of the abdominal region. It would api)ear to be for the 

 protection of this important organ that the coracoids are extended 

 backwards. The cavity anterior to the heart is occupied by longitudi- 

 nal muscles and the largo larynx. The lobes of the liver extend each 

 t') the groin, a position even more posterior than in those genera of 

 Ivaniformia which are characterized by the posterior position of that 

 organ; and by the disai)pearanceof its median lobe, and the wide sep- 

 aration of ils lateral lobes for the aeeommodation of the heart. The 

 gcncia in wliich lliis relation exists, are Ibeviiu'ps, Engystoma, Sys 

 toma, (Jallula, IMirynomantis, Atelopus, and I'lpa.
