BACAS-CHAMIRI or BACASCAMI, one of the three towns of the Zamareni, a tribe of the interior of Arabia, mentioned by Pliny without any clue to their geographical position (6.28. s. 32). It is a probable conjecture of Forster that Chamari points to Gebel Shammar, a mountain to the north of the peninsula, and that the Zamareni are identical with the Beni Shammarof Burckhardt, whom he further identifies with the Saraceni of Ptolemy. ( Geog. of Arabia, vol. 2. p. 241.)
