Some Observations on Caudal Autotomy and Regeneration in the Gecko (Hemidactylus flaviviridis, Rüppel), with Notes on the Tails of Sphenodon and Pygopus.

ABSTRACT During the rainy seasons (July to October) of 1914 and 1918 I made a large number of observations and experiments on the facts of caudal autotomy and regeneration in the common Indian Gecko, Hemidactylus flaviviridis1 (Rüppel), a very familiar and useful ‘snapper-up of unconsidered [insect] trifles ‘found on the walls of every bungalow in the United Provinces. In January 1915 I read a brief paper2 on the subject at Madras on the occasion of the second meeting of the Indian Science Congress, but until the present year I have not had an opportunity of writing up a complete description of the results obtained by me.
