The Barhisads, the sons of Atri, are declared to be the Pitṛs of Daityas, Dānavas, Yakṣas, Gandharvas, Uragas, Rākṣasas, Suparṇas and Kinnaras.—(196)

Medhātithi’s commentary (manubhāṣya):
All these, Daityas, &c., though not worthy of being mentioned in scriptures, have been mentioned here for purposes of the laudatory description. The forms and character of these beings are as described in the Itihāsas.

‘Suparṇas’—are a particular kind of birds.

‘Kinnaras’—are horse-faced beings.

The purport of this laudatory description is that—so essential is the performance of Śrāddhas that even Daityas, Dānavas and Rākṣasas, who generally interfere with sacrificial performances, cannot avoid it; nor even animals, who have no intelligence and no memory.

The sons of Atri are called ‘Barhiṣads.’— (196)
