Cottiaris
Cottiaris (Ptol. 7.3.3; Marcian. p. 30), a river of China, at the southern end of that empire, on the banks of which lived, according to Ptolemy, the Aethiopian Icthyophagi. It is difficult to determine to what river this name ought to be referred; hence Mannert has conjectured that it is a river of Borneo, and Forbiger that it is the Si Kiang, the river of Canton, which, agreeably with this view, he imagines to be the same as the Cattigara of Ptolemy. This seems the best suggestion.
