The species Bucephalopsis karvei n. sp. has been described in detail and separated from the allied species. A survey of the work on Bucephalidæ has been given and the species B. magnum, B. confusus and B. minimus have been considered to be synonyms of B. garui. A key to the existing valid species of Bucephalopsis has been given.The genus Catoptroides has been merged into the synonymy of Phyllodistomum and arguments for so doing have been advanced. Revised diagnosis of Phyllodistomum has been given.Phyllodistomum shandrai n. sp. has been described and separated from the allied species. P. sp. has been briefly described. Key to the species of Phyllodistomum has been given.Paramphistomum maplestoni n. sp. and P. cuonum n. sp., have been described and separated from the allied species P. orthocœlium. A few observations on P. sp. from a wild cat and Diplodiscus amphichrus from Rana tigrina have been recorded. Paramphistomum cervi, P. sp., Cotylophoron orientalis and Gastrothylax crumenifer have been recorded from neelgai, hog deer and sable antelope respectively.Helostomatis sakrei n. sp. has been described and separated from H. helostomatis. A revised diagnosis of Helostomatis has been given.Neocladorchis poonaensis n.g., n. sp. has been described. The new genus Neocladorchis has been defined and separated from the allied genera.

Blood Meals

From January to July 1938, experiments with Anopheles maculipennis race atroparvus, Van Thiel, were undertaken to discover whether humidity and the age at which the females fed influenced their longevity. It was found that they lived longer at higher than at lower humidities; that most of the females which fed did so in the first three days; that those which fed on the second day after emergence lived longer than those which fed at other ages; and that the feeding period was slightly extended in the later experiments, though only a small proportion lived long enough to take their first blood meals on the fourth and fifth days.Rather more than 50 per cent. of each batch of newly emerged adults were females.A large proportion of the deaths of unfed males and females occurred during the first three days, most of them on the second day; this mortality decreased in successive experiments.Culex fatigans, Wied., behaved similarly.

Kinetics Of

We determined the kinetics of metamorphosis, apoptosis, and tail regression in Rana tigrina. Acid phosphatase activity (µMole Pi.hr-1.tail-1) in the growing and regressing tail attended six to thirty fold increase respectively. However total activity in the trunk was decreased through progressive growing stages of metamorphosis. Total protein content in the trunk of tadpoles at climax stage (XXI) was decrease (35%) from 2.6mg/ml to 1.7mg/ml. The tail of tadpole tissue has shown a two fold increase in total Ribonucleic Acid (RNA) content from stage III to stage XVIII. But there was again decrease in total RNA content at climax stage (stage XXI). This might be possible due to decreased protein synthetic status. When the experiment was performed in trunk homogenate the amount of total carbohydrate (mg/ml) was slightly increased from 37mg/ml to 38.6mg/ml. this might be due to increase in the activity of α-amylase enzymes in the viscera of developing tadpole when it reached the climax stage.
