was investigated. Each of the five adult porcupines (three

males, two females) was injected with a coloured latex mixture

via the V. cava caudalis for the demonstration of the cardiac

veins. The dissection of the specimens revealed that the venous

drainage of the heart in porcupines was made by the V. cordis

magna, V. distalis ventriculi sinistri, V. proximalis ventriculi

sinistri, V. cordis caudalis (the left marginal vein), V. cordis

media and Vv. cordis dextrae. The cardiac veins were observed

in a subepicardial course on the heart except for the

R. interventricularis paraconalis. The R. interventricularis

paraconalis showed an intramyocardial course until the middle

of the sulcus interventricularis paraconalis, and a subepicardial

course after this point. The V. cordis magna and V. distalis

ventriculi sinistri opened to the sinus coronarius. The V. cordis

caudalis and the V. cordis media drained into the V. cava

caudalis. The venous drainage of the conus arteriosus was

made by the left V. coni arteriosi opening to the R. interventricularis

paraconalis, and by the right V. coni arteriosi

which continued to the Vv. cordis dextrae.
