The per cent decrease of glycogen content in all the tissues investigated is more in 20-days starved snails than the 4-months aestivated snails when compared to active snails. Recovery of administered glucose-U-14C in the respiratory CO2 is 42·27% in active snails, whereas it is 8·81% and 26·09% in aestivated and starved snails respectively. Maximal levels of incorporation of labelled glucose were found at 18 hr in all the tissues and the rate of incorporation was greatly elevated in the tissues of aestivated and starved snails. The causes for the difference in the rates of incorporation and the utilization of glycogen in active, aestivated and starved snails are discussed.

The copper and protein content in the blood and in the purified haemocyanin of active and aestivated snails are determined. There is a marked increase in the copper content and also in the haemocyanin content in the blood upon aestivation which is discussed in the light of the available literature. The per cent copper/protein ratio was 0·255 in the purified haemocyanin of the active and aestivated snails, suggesting similar nature of haemocyanin molecule whose minimal molecular weight was calculated to be 24,910.

The copper and protein concentrations in the blood and in the purified haemocyanin of active and starved slugs were determined. During starvation there is a marked decrease in the haemocyanin concentration in the blood. However the copper protein ratio of the purified haemocyanin of the active and starved slugs remained unchanged suggesting that haemocyanin remains unaltered during starvation.
There is a significant increase of hepatopancreatic copper upon starvation. The hepatopancreas is suggested to store copper during starvation. The results are discussed in the light of the previous works on crustaceans and molluscs.

The changes in the levels of total anthrone positive substances glycogen and glucose and the activities of phosphorylase, lactate dehydrogenase and succinate dehydrogenase were studied in the

The copper and protein contents have been determined in the blood and also in the purified haemocyanin of the freshwater field crab,

Elevation in the levels of the blood inorganic ions and depletion in the levels of the blood organic reserves, except TNPS, noticed during ‘starvation regime’ of the slug are discussed irt view of their specific roles in energy metabolism.
