A new deep-sea crab, genus Chaceon, from the Arabian Sea (Crustacea, Decapoda, Geryonidae)

The sixth nominal species of Chaceon to be recorded from the western Indian Ocean is named from a specimen collected off Somalia in 504-506 meters. Chaceon somaliensis, n. sp., resembles C. macphersoni (Manning and Holthuis, 1988) and differs from the other four species known from the area in having the dactylus of the walking legs dorsoventrally depressed. It differs from C. macphersoni in having slenderer legs, a smoother body, and a much deeper, evenly curved orbit.

Rotifera from Sri Lanka (Ceylon) 1. The genus Lecane with description of two new species

The present study is based on collections made from a large number of lakes, ponds and paddy fields during the period 1968-1972. A large number of new records and some new species have been identified in this material. The largest number of species have been recorded in the genus Lecane i.e. Lecane (Lecane), Lecane (Hemimonostyla) and Lecane (Monostyla) and the present paper is restricted to this genus. In all 25 species including two new species are recorded and described.

Excirolana orienta/is (Dana, 1853) belonging to the Cirolanidae, hitherto unknown from Pakistan, is collected from the rocky intertidal region of Manora Island, Karachi coast The specimens are fully described and illustrated. A list of the known species of the genus Excirolana is also provided since the genus is also first time reported from here.

Phylogenetic and systematic study of the genus Bombina (Amphibia : Anura : Bombinatoridae): New insights from molecular data

Phylogenetic relationships and systematics of the eight currently recognized species of the genus Bombina were investigated using four mitochondrial gene fragments (16S rRNA, 12S rRNA, ND4-tRNA(LEU), and cytochrome b). We prepared two different concatenat
