1. The Neutral Red technique was employed to study the filtration rates of
2. It appears that low salinity has a great depressing effect upon the rate of filtration in
3. Light has got no effect on the filtration rate.

1. A detailed morphological description of the neurosecretory cells in the hermit crab,
2. The optic ganglia and sinus gland are incorporated within the brain.
3. Three types of neurosecretory cells, designated as A, B and C, are encountered in the central nervous organs other than the eyestalks. They are distinguished by their sizes, the nature of the nuclei, vacuoles and the secretory products in the cytoplasm. All the three cell types occur in the supraoesophageal ganglia, thoracic ganglion and abdominal ganglia while the commissural ganglia possess only A and B cells.
4. The secretory products appear to be discharged through the axons. The direct discharge of secretions into the blood capillaries surrounding the cells is also noticed.

1. The detailed morphological structure of neurosecretory cells in
2. Histological structure of the optic tentacle reveals that it consists of three types of neurosecretory cells of which the collar cells are situated around the central ganglia while the others are laterally down the sides of dermo-muscular wall. They are PAS positive and sudanophilic.
3. Cell type B showed a distinct annual cycle of activity which is correlated with the annual reproductive cycle of
4. The effect of cutting the tentacles showed that number of eggs was increased in optic tentacles-cut animals. The tentacle homogenate injected animals showed no increase in number of eggs but the brain homogenate injected animals showed considerable increase in the number of eggs.
5. The amount of neurosecretory material in cell type A decreased from lower to higher salt concentrations. It may conclude that cell type A plays an important role in water balance as anti-diuretic factor.
