from The Century Dictionary and Cyclopedia
- In botany, having four cells or compartments; four-celled: as, a quadrilocular pericarp.
- In anatomy and zoology, having four cavities or compartments: chiefly an epithet of the heart of mammale and birds.
The heart is not quadrilocular (i.e., of four chambers), but trilocular (of three), and two structures, not seen in Lepus, the truncus arteriosus and the sinus venosus, into the latter of which the venous blood runs before entering the right auricle, are to be noted.
