However, the "Matsya Purana" mentions the "Shunga-Shaishiri" "dwaimushyayana" gotra (named "Shaunga-Shaishireya" here) as a combination of the Bharadvaja and Kashyapa (not Vishvamitra) gotras. The "Harivamsa" mentions a twice-born general of the Kashyapa gotra who performed the Ashvamedha sacrifice. Some scholars such as Jayaswal identify this general with Pushyamitra. The "Malavikagnimitra" describes Pushyamitra as a "Baimbaki". H. C. Raychaudhuri, who read this term as "Baimbika", identified it with Baimbakayah of the Baudhayana Shrauta Sutra, who was of the Kashyapa gotra (although other scholars believe that the term "Baimbaki" signifies descent from a person named Bimba, or refers to a heroic lover in general). Bela Lahiri theorizes that the constituents of a "dwaimushyayana" gotra may have differed during different periods, and Pushyamitra may have belonged to one of these gotras.
