The pattern described in the rhyme scheme of this stanza by William Butler Yeats is called the ABCB rhyming pattern. If the entire 8 lines are considered, then it becomes (ABCB; BCDC).
To see this flow, one would have to examine the full poem.
Limited to the excerpt in the question alone, we'd have a rhyme scheme that reads ABCB.
This is because the second and last line ends with the same rhyme but the second and the first don't.
Another example of the rhyme ABCB is given below:
Read this sentence as it flows, (A)
in this line, three ts occur, (B)
maybe I should write a book, (C)
and make things rhyme some more (B)
