Our knowledge of the fish of the Anamalai and Lelliampathi hill ranges lying immediately south of the Palghat Gap is very scanty. Considerable importance has been attached in recent years to the Palghat gap as a probable barrier in the distribution of torrential fishes along the Western Ghats. Zoogeographical studies have revealed that this gap, in the otherwise continuous mountain ranges, has had profound effects in the southward distribution of certain forms animals. Though considerable work has been done on the fish fauna of the Central Division in recent years, the regions immediately south of the Palghat Gap have remained practically unexplored. What a little we know about the fishes of this region, we owe to work of Day (1865) and more recently to that Herre (1942,45). After his visit to India in 1941, Herre reported the discovery of two new fishes from the Anamalai Hills, one a Sisorid catfish Glyptothorax housei, Herre and other a homalopteriod, Homaloptera montana Herre. In addition he extended the distribution of the remarkable homalopterid Travancoria jonesi Hora, previously know only from the hill ranges of northern and central Travancore, the Anamalai Hills in the north
