Malayalam summary of a Sanskrit work under the title Gralhapariks6 krama. The textual verses were not available to the editor and he presumed that the author was Drganita-Parameswara. * These verses are however, found in Nilakantha's Bhasya on the Golapadld of the 2,४५0 blafrya, under verse 48 (7SS 185, pp. 132-49). It is a long tract of about 200 verses, summing up the principles and methods followed in Hindu astronomy a:nd forms a veritable handbook on the subject.

UIloor attributes t0 Nilakantha a work called Ga१ity!ikti. Thus, speaking about a Bhaऽyuktiblds, he says that “it is 10t the work of Kelallur Comatiri, author of Gapitayukti.”* The ascription is wrong and the fact is that while our author belonged to the Gargya-gotra, this latter work is by an anonymous author belonging to 1.
