Abstract
Two basic types of haemocytes i.e., granulocytes and hyalinocyte were present in the blood of snail. Bensonies jacquenunni. Most of the haemoeytes observed (97.2%) were gnmulocytes. Their diameter varies from 1)i-36 trin. Ectoplasm was not very distinct. The endoplasm have granules of various sizes. The pseudopodia are either lilopodia or lobopodia. Each granulocyte forms 2-17 filopodia which are upto 12-62 long. Terminal or basal webs showed dichotomous branching or branches on one side. Granulocytes can merge with each other or with hyalinocytes thus loosing their cytoplasmic identity and form large aggregates of cells. The nucleus of granulocytes was rounded to oval. kidney-shaped or lohulated. 9-12 hint in size. llyalinocytes (2.8%) were rounded cells, without pseudopodia. have diameter 13-42 nni. They differed from granulocytes in the presence of few granules. in having hyaline ectoplasm. The nucleus of hyalinocytes was rounded to oval or somewhat oblong with diameter 9-12 irm. A few spent granulocytes and hyahnocytes were also present. Some haemocytes (2-3%1 of B. jut quemonti were found binucleated.
