title: Haematology of the common Indian frog Rana tigrina I. erythrocytes.
abstract: A study of erythrocyte count and size in Rana tigrina has been made over a period of two years. The erythrocyte count exhibits a wide range showing a month to month variation in both the sexes. An average count of 15,93,600 in females and 10,29,700 per mm3 in males is recorded. These values are appreciably high from March to July with a peak in May and June for males and females respectively. The starvation brings about a decrease in counts generally from 12th day onwards. The size of erythrocytes averages 20.7 X 13.4 micrometer in length and width. No difference in size was observed in respect of sex or season.
