Before entering upon an account of the Koi, I ought to say that I am going to describe those only, with whom I came in contact during my residence at Dummagûdem, in the Bhadrachellam taluqa of the Godávari District, giving at the same time additional information gleaned from them respecting those of their tribe, who live further inland, on the uplands of the bordering semi-independent state of Bastar. The place furthest south, where I have met with Koi, is Kammameta, in the Nizam's dominions. At present I know of eight classes or castes of the Koi, the Oḍḍî, Guṭṭa Koi, Gommu Koi, Linga Koi, Koi Nâyak, Koi Kammara, Ḍôlivânḍlu or Ḍôlôllu, and Paṭṭiḍivanḍlu.
