A redescription of Diogenes senex Heller, 1865, sensu stricto (Decapoda: Anomura: Paguridea: Diogenidae)

Diogenes senex Heller, 1865 sensu stricto is redescribed from specimens collected in Australia, particularly in and around the type locality of Sydney. A neotype has been designated. Comparisons of this material with other specimens identified as D. senex by a number of authors has shown that at present only the Australian material truly represents Heller's taxon.

An illustrated key to the Malacostraca (Crustacea) of the northern Arabian Sea. Part 6: Decapoda anomura

The key deals with the Decapoda, Anomura of the northern Arabian Sea, belonging to 3 super-families, 10 families, 32 genera and 104 species. With few exceptions, each species is accompanied by illustrations of taxonomic importance; its first reporter is referenced, supplemented by a subsequent record from the area. Necessary schematic diagrams explaining terminologies are also included.

Distribution of decapod larvae in the Bombay Harbour-Thana-Bassein Creek regions

Variations in the abundance and composition of larval decapods were studied from 90 km stretch of the Bombay Harbour-Thana Creek-Bassein Creek (BHTCBC) system for a period of 15 months. The larvae belonged to Penacidea, Caridea, Anomura and Brachyura. Among these, brachyurans were the most abundant in the entire study area indicating good potential for crab fishery. Penaeus, Metapenaeus and Parapenaeopsis were the genera recorded in the family Penaeidae of which Metapenaeus spp. were the most common. Generally there was a higher abundance of Penaeus and Metapenaeus during monsoon probably indicating intense breeding. A few genera of decapods showed patchy occurrence in this system. Results of this first investigation were quantitatively and qualitatively evaluated with comments on fishery potential of the commercially important groups of decapods.
