Nattier discusses briefly Hirakawa's hypothesis (Shoki daijō ni okeru tōji no imi 初期大乗における塔寺の意味, 1957) that the Ugra-paripṛcchā included in the Ratnakūṭa T310(19) is a translation mentioned in the tradition, thought lost, by Dharmamitra. Nattier herself takes the position that although this hypothesis is worth considering, further work is required before it can be regarded as established. She notes that Dharmamitra was first credited with a translation of the Ugra-paripṛcchā in LDSBJ; CSZJJ only ascribes four titles to him, and the Ugra-paripṛcchā is not among them.
