DESCRIPTION OF FIGURES. 
Heart of Diemyctylus viridescens (semi-diagramatic) to 
show the general relations of the heart of a salamander with 
lungs. The ventral wall of the heart has been removed in 
order to show the auricular septum, the openings of the sinus 
venosus and the pulmonary vein, and also the relation of the 
auriculo-ventricular aperture to the right and left auricle.

venosus; 5. Bulbus arteriosus; 6. Auricular septum; 7. 
Auriculo-ventricular aperture; 8. Aperture of sinus ven-

Heart of Desmognathus fusca (semi-diagramatic) to show 
relations of the heart in alungless salamander. The ventral 
wall of the heart has been removed.
