Wilson has identified Ka-pi-li with the Kapili river of Assam named in the Kalika purana as Kapila-Ganga, and Vincent Smith has tentatively accepted this identification. The Kapili valley, which is still called Davaka, may be identified with the kingdom of Davaka mentioned in the Allahabad inscription of Sumudra Gupta. The embassy may therefore have been sent by the king of Davaka whose name was either Chandra Priya or Chandra Vallabha. It should however be mentioned that there was a king of Kamarupa named Chandra-mukha (moon-faced) who was the great-grandfather of Bhaskaravarman. He cannot, however, be assigned to the second quarter of the fifth century. It seems that in the sixth or the seventh century this kingdom of Davaka was absorbed by Kamarupa, for according to Xuanzang's account the Kapili valley was included in Kamarupa. The kings after Balavarman were Kalyanavarman, Ganapativarman, Mahendravarman and Narayanavarman who do not appear to have been much renowned. According to the Nidhanpur inscription, Ganapativarman was generous in his gifts while Narayanavarman was, like king Janaka, deeply versed in the knowledge of the self. Narayanavarman was succeeded by his son Mahabhutavarman who is named in the Harsha Charita as Bhutivarman. It was he who granted, to a large number of Brahmans, lands in the Chadrapuri vishaya. The copper-plate relating to this grant having been destroyed by fire his great great grand son Bhaskaravarman recorded, what is known as the Nidhanpur grant, to confirm the gift made by his ancestor. Originally only three plates of this inscription were discovered by Pandit Padmanath Bhattacharya Vidya Vinod who contributed a paper on them in Epigraphia Indica vol XII. Subsequently, two more plates found were described by Pandit Vidya Vindod in XIX of the Epigraphia Indica. The third lost plate was again discussed by him in the same journal. One more plate is still missing. The newly discovered plates mention the names of Chandrapuri vishaya, Kausika River and Mayura-Salmala agrahara. The occurrence of the word "agrahara" seems to indicate the existence of a temple for the maintenance of which and its Shebaits the lands were granted.
