リーダーズ+プラス, Eijiro

Apropos of 同韻語, リーダーズ+プラス gives it as the Japanese gloss for "rhyme", and Eijiro has: 
同韻語の {形} : rhyming
同韻語辞典 : rhyming dictionary

I ran across this in a book, and a google search turned up a number of instances.

同韻語 should probably also be an entry, but based on what I've found, I'm not actually sure if it is a noun meaning "rhyme" or an adjective meaning "rhyming".
