Springer, Victor G., and Thomas H. Fraser. Synonymy of the Fish Families Cheilobranchidae ( = Alabetidae) and Gobiesocidae, with Descriptions of Two New Species of Alabes. Smithsonian Contributions to Zoology, number 234, 23 pages, 14 figures, 3 tables, 1976.—The genus Alabes, monotypic representative of the Cheilobranchidae, shares a large number of specializations with the members of the Gobiesocidae, including one not known to occur in any other fishes: the supracleithrum bears a shallow, concave process at its distal end that articulates with a convex condyle on the anterior surface of the cleithrum. A vestigial, papillae-bearing "sucking disc" occurs in some specimens of Alabes dorsalis. On the basis of shared specializations, we consider the Cheilobranchidae to be highly specialized gobiesocids. The osteologies of Alabes dorsalis and the gobiesocid Trachelochismus pinnulatus are illustrated. Four species are recognized in Alabes: dorsalis (widespread in southern Australia and Tasmania), parvulits (widespread in southern Australia, Tasmania, and Norfolk Island), brevis (new species from Western Australia), and hoesei (new species from New South Wales, South Australia, and Tasmania). OFFICIAL PUBLICATION DATE is handstamped in a limited number of initial copies and is recorded in the Institution's annual report, Smithsonian Year.

Fish assemblages and habitat ecology of River Pinder in central Himalaya, India
Snow-fed river Pinder -a tributary of river Alaknanda in central Himalaya was explored for fish assemblages and habitat specificity. Altogether 27 fish species were reported from three orders, four families and nine genera. Cypriniformes order was dominating followed by Siluriformes and Salmoniformes. Shannon-Weiner diversity index (3.09 to 4.10) and Simpson index of diversity (0.81 to 0.92) of...
