How would you define the following rhyme scheme from this stanza taken from the epic poem, Cacey's Revenge:

A dismal groan in chorus came – a scowl was on each face –
When Casey walked up, bat in hand, and slowly took his place;
His bloodshot eyes in fury gleamed; his teeth were clinched in hate;
He gave his cap a vicious hook and pounded on the plate.
