Abstract

Barney and Anson (1921) in writing of the fluctuating sex-ratio in the common top-minnow, Gambusia affinis B. & G., have expressed conclusions with respect to a differential death-rate for the sexes quite at variance with data of my own. Briefly stated, they conclude that in the shipping of Gambusia for stocking ponds in mosquito-control work, the female has a higher death-rate than the males and they explain this upon the assumption that the male is more resistant to high temperatures than the female.
