Abstract
The aim of the present study was to characterize the patterns of gastropod shell utilization by the hermit crab Clibanarius zebra from four different sites along the Saurashtra coast, Gujarat state, India. A total of 404 individuals of hermit crab were captured (223 males, 147 females and 34 ovigerous females), occupying 22 species of gastropod shells. Maximum species diversity of shells occupied by the crab was observed at Veraval. Amongst all the shell species identified, Cerithium scabridum (36.88 %) was highly occupied by the crab species followed by Astra stellata (11.39 %), Turbo intercostalis (10.64 %), Cerithidia cingulata (9.16 %) and Lunella coronata (7.43 %). Males of C. zebra utilized a wide range of shell species (21 species), while non ovigerous females (13 species) and ovigerous females (7 species) use a specific set of gastropod shell species. The density of live common shell species occupied by C. zebra was also calculated and results revealed that the density of C. scabridum was very high in the intertidal zone compared to other gastropods. This indicates that density of shells may influence the utilization of shells by C. Zebra.

*Corresponding author. E-mail: rajeshvsanap@gmail.com
Abstract
The genus Plesiophrictus Pocock (1899) was described when found in Matheran to embody P. millardi. This species was described based on a male specimen, but the female remained unknown for more than a century. Recent surveys conducted in the known range of the species resulted in the discovery of the female, which is herein described for the first time.

A taxonomic note on Impatiens disotis Hooker, 1906 (Family: Balsaminaceae)
E.S.S. Kumar*, A.G. Pandurangan & P.E. Roy
*E-mail: santhoshkumares@gmail.com
The genus Impatiens consists of over 1000 species distributed in the Old World tropics and subtropics. In India, the genus is represented by more than 200 species that occur mainly in three major centers of diversity, Western Himalayas, North East India, and the Western Ghats, of which the state of Kerala harbours 72 species, most of which are rare, endangered or threatened.

Cannibalism of Indian Palm Squirrel (Funambulus palmarum)
G.M. Edirisinghe* & B.S.A.T.H. Sudasinghe
*E-mail: hsudasinghe@gmail.com
The palm squirrel is one of the common small mammals in Sri Lanka and the Indian Palm Squirrel (Funambulus palmarum) is the commonest of all being distributed throughout the island. All palm squirrels are essentially herbivores, however diet varies depending on the species. F. palmarum has a broad, opportunistic diet, consuming a range of foods that vary depending on season. Its diet includes nuts, a range of seeds, fruits, flowers, young shoots, barks, lichens and it occasionally eats insects such as termites and beetles.

Rhesus macaque and associated problems in Himachal Pradesh - India
V. Singh* & M.L. Thakur
*E-mail: proliterate@yahoo.com
Conflict between humans and primates is common and increasing. Of the nearly 225 living species of nonhuman primates, three Indian species (i.e., rhesus macaque (Macaca mulatta), bonnet macaque (Macaca radiata) and the hanuman langur (Semnopithecus entellus) have become urbanized. Out of these, rhesus macaques and hanuman langur share food and space with humans in rural and urban areas and are often reported in conflict with humans. Conflicts often occur when these primates raid crops of farmers
