Taxometric analysis of helminthes of marine fishes. 1. Pedunculacetabulum spinatum n.sp., from Chorinemus mandetta and Wenyonia rhincodonti n.sp., from Rhincodon typus.

The investigations include report of two new worms from marine fishes of Central West Coast of Goa in Arabian Sea. A trematode, Pedunculacetabulum spinatum n.sp. from Chorinemusmandetta and Wenyonia rhincodoni n.sp. from sharks, Rhincodon typus have been described and compared with closer species. The systematics of genus Pedunculacetabulum Yamaguti (Japan J Zool 6:1-112, 1934) has been discussed with detailed evidence of taxometric significance to reinstate this genus.

A new cestode Raillietina (Skrjabinia) doggaddaensis n. sp. from Gallus gallus domesticus (L.) from India.

Anew poultry cestode Raillietina(Skrjabinia) doggaddaensis n.sp.has been described from the domestic fowl Gallus gallus domesticus (L.). The new species has been compared with R.(S.) dhuncheta Sharma (1943) and R.(S.) magnicoronata(Fuhrmann, 1908).

On A New Reptilian Cestode Oochoristica Pauriensis N.Sp. From Hemidactylus Brooki (Gray) And Hemidactylus Flaviviridis (Ruppell) From Garhwal Hills, U.P., India.

Oochoristica pauriensis n.sp. has been described and figured from Hemidactylus brooki(Gray) and H. flaviviridis(Ruppell) on size of strobila, scolex, suckers, testes, ovary, eggs and oncosphere, and number of testes. The new species has been compared with close species.

Comparative analysis of amino acids of three species of gangesia (Cestoda: Proteocephalata).

A total of 21 amino acids were detected in the present investigations on three species of Gangesia (Cestoda: Proteocephalata) viz. G. bengalensis Woodland, 1924, G. hanumanthai Seth & Capoor, 1982 and G sanehensis Malhotra et al., 1981. The study was conducted in a sub-humid region around Allahabad, India. The implications of amino acid utilization in metabolic activities of fish tapeworms have been discussed.

Chemotaxonomic studies on davaineid tapeworms, based on amino acid analysis.

Twelve amino acids were detected in six davaineid cestodes, Davainea hewetensis Dhawan & Capoor (1972) collected from one Gallus gallus domesticus L. at Allahabad, India. Chemotaxonomic studies within the family Davaineidae have shown the presence of cystine and hydroxyproline only in D. hewetensis, although phenylalanine and proline occur in all species examined previously.

Amino acids of Hymenolepis palmarum (Johri, 1956) and chemotaxonomic studies on hymenolepidid cestodes.

Chemotaxonomic patterns in the distribution of amino acids of Hymenolepis palmarum (Johri, 1956) and other hymenolepidids revealed the common presence of beta-aminoisobutyric acid, lysine, phenylalanine and tyrosine but 3,4 dihydroxyphenylalanine and norleucine were exclusive to H. palmarum. Both qualitative and quantitative differences in amino acids have been recorded.
