    • Two new species of the genusMonocercomonoides travis, 1932 (protozoa: Mastigophora) from reptiles

      R Krishnamurthy

      More Details Abstract Fulltext PDF

      The paper contains an account of two new species of flagellates,Monocercomonoides singhi n.sp., from the chameleon in Hyderabad (A.P.) andMonocercomonoides mehdii n.sp., from the garden lizard in Aurangabad (M.S.). The former measures 8·72 × 7·25µ and is characterized by a short rod-like funis and a J- or L-shaped axostyle but is devoid of a pelta. The latter is much larger, measuring 11·44 × 10·57µ, and has a thin and straight axostyle but is devoid of both funis and pelta.

    • Tetrasomaty in the roots ofCicer arietinum Linn.

      G Meenakshi M K Subramaniam

      More Details Abstract Fulltext PDF

      Sporadic instances of tetrasomaty in the primary and secondary roots of five varieties ofCicer arietinum Linn. are illustrated. The phenomenon was more common in Varieties I and II. The SAT-chromosomes are reliable guides to estimate the degree of polysomaty, since pre-treatment withp-dichlorobenzene revealed that cell types with 32 chromosomes at metaphase had two pairs of SAT-chromosomes associated with the nucleolus at prophase. Tetrasomatic cells appear to be limited to the dermatogen and periblem. Higher degrees of polysomaty were not observed.

    • Geology of Eastern Ghats in Andhra Pradesh

      A Sriramadas

      More Details Abstract Fulltext PDF

      The lithology, structure, metamorphism and stratigraphy of the granite gneisses, charnockite series, khondalite series and granites occurring in the Eastern Ghats of Andhra Pradesh are described. The granite gneisses consist of the garnetiferous granite gneiss, the grey granite gneiss and porphyritic granite gneiss. The charnockite series consists of granite, diorite, gabbro, norite, amphibolite and pyroxenite. The khondalite series comprises gneisses, schists, quaitzites, and granulites, metamorphosed from argillaceous, arenaceous and calcareous sediments. The granites include the pink granites and pegmatites. The formations are highly folded with thrusts and strike slip faults. The granite gneisses, charnockite series and khondalite series are metamorphosed to the granulite facies, with a few members in the amphibolite facies and occasional members in the eclogite facies. Some granite gneisses are the oldest rocks present, and others contemporaneous with charnockite series, which are themselves older than or contemporaneous with the khondalite series. The pink granites and pegmatites are the youngest rocks of the region.

    • Fishes of the genusIlisha richardson, 1846 from Visakhapatnam

      S Dutt

      More Details Abstract Fulltext PDF

      Twelve species of genusIlisha Richardson, 1846 are recognised to date. The genus and constituent species are badly in need of revision. Five of the twelve species have so far not been recorded from India.

      Of the seven species recorded from India, the type locality of two speciesIlisha indica (Swainson) andI. megaloptera (Swain.), is Visakhapatnam and of a third speciesI. filigera (Val.) is Coromandel Coast. Descriptions of these three species based on new material from Visakhapatnam are given, because earlier descriptions are inadequate or partially incorrect.

      The salient features of the posterior frontal fontanelles and the vertebral column are given.

    • On some marine interstitial gastrotrichs from the beach sands of Waltair Coast

      P N Ganapati G Chandrasekhara Rao

      More Details Abstract Fulltext PDF

      The paper reports for the first time the occurrence of thirteen species of interstitial Gastrotrichs in the beach sands of the Waltair Coast which were previously reported from European waters. Eight of the species representing seven genera belong to the order Macrodasyoidea and the remaining five representing three genera come under the Chaetonotidea. The distribution of these forms is described with reference to the tidal levels, the grain size of the sand, the temperature and salinity ranges of the environment.

    • Effect of viomycin adaptation on decarboxylase activity ofAerobacter aerogenes

      K C Agarwal J P Shukla

      More Details Abstract Fulltext PDF

      The decarboxylase activity of Glutamic acid as well as α-Ketoglutaric acid which as a result of training in the medium having viomycin decreases in the trained cultures but returns towards the normal level in the reverted cultures, indicates the development of an adaptative enzyme balance in the organism due to the action of viomycin.
