Translation: 
There, among the brāhmaṇas, Śrī Caitanya Mahāprabhu listened to the Kūrma Purāṇa, wherein is mentioned the chaste woman’s narration.
Purport: 

Śrīla Bhaktisiddhānta Sarasvatī Ṭhākura remarks that only two khaṇḍas of the Kūrma Purāṇa are now available, namely the Pūrva-khaṇḍa and Uttara-khaṇḍa. Sometimes it is said that the Kūrma Purāṇa contains six thousand verses, but according to Śrīmad-Bhāgavatam the original Kūrma Purāṇa contains seventeen thousand verses. It is considered the fifteenth of the the eighteen Mahā-purāṇas.
