      The present paper deals with the description of subcutaneous fat-bodies found inRana tigrina. It is found that apart from minor deposits of adipose tissue within the lymph spaces here and there, there are five definitely localised corpora adiposa under the skin: four on the ventral surface, and one on the dorsal. The situation of these fat-bodies in relation to muscles and lymphatic septa, their blood-supply and histology, as well as their variations in size, colour and extent are recorded.

      1. The general development of the mesonephros inBufo is similar to that ofRana (Gray, 1930) andRhacophorus (Reddy, 1938).

      2. Each malpighian unit arises from a nephroblast vesicle which is a condensation of 14 to 16 blastema cells.

      3. 10 to 13 nephroblast vesicles are developed.

      4. The rudiment of the early peritoneal funnel appears as condensation of 4 to 6 blastema cells in front of the nephroblast vesicles.

      5. The condensation is simultaneous with that of the nephroblast vesicle.

      6. The rudiment develops after the perfection of the early malpighian capsule and establishes a connection between the cœlom and blood circulation.

      7. The early peritoneal funnels persist while early malpighian capsules with their tubules and glomeruli degenerate and disappear.

      8. The straight tubules and their outgrowths arise from 13 to 15 condensations on the dorsomedian wall of the archinephric duct.

      9. At the free end of the tubule is an abortive malpighian capsule.

      10. At the free end of each outgrowth or secondary tubule is a condensation of capsuloblast vesicle.
