Note 5 — Chapter XXVII · PÂṬALIPUTTRA OR PATNA, IN MAGADHA. KING AŚOKA’S SPIRIT-BUILT PALACE AND HALLS. THE BUDDHIST BRAHMAN, RÂDHA-SÂMI. DISPENSARIES AND HOSPITALS.

So, by the help of Julien’s ‘Méthode,’ I transliterate the Chinese characters 羅太私迷. Beal gives Râdhasvâmi, his Chinese text having a 婆 between 私 and 迷. I suppose the name was Râdhasvâmi or Râdhasâmi.
