It was taken in Bung Borapet, Central Thailand, November 24,1933. Remarks.—At the time the type specimen was captured it was recognized as peculiar, and additional specimens were sought during many years. The species may be distinguished from the described Thailand and Indian species by a combination of characters, includ- ing rather small scales, two pairs of barbels, curiously papillate lower lip, and apparently small size, for the type is a female with ovaries extending the entire length of the abdominal cavity.
