Abstract
During present study a review on scheme of classification of fishes by earlier researchers has been undertaken. An attempt has been made to forward a new scheme of classification by correlating the habits of teleostean fishes with degree of development of brain and development, disposition and branching of the cranial nerves. Besides this, inconsistencies in the different species of genera like Mystus and Labeo have also been discussed in detail.
