Word for word: 
atha — now; kaśyapa-dāyādān — the sons of Kaśyapa; daiteyān — born of Diti; kīrtayāmi — I shall describe; te — to you; yatra — where; bhāgavataḥ — the great devotee; śrī-mān — glorious; prahrādaḥ — Prahlāda; baliḥ — Bali; eva — certainly; ca — also.
Translation: 
Now let me describe the sons of Diti, who were begotten by Kaśyapa but who became demons. In this demoniac family the great devotee Prahlāda Mahārāja appeared, and Bali Mahārāja also appeared in that family. The demons are technically known as Daityas because they proceeded from the womb of Diti.
