HISTOLOGICAL AND STRUCTURAL OBSERVATIONS ON PRE-ANAL GLANDS OF THE GEKKONID LIZARD, HEMIDACTYLUS-FLAVIVIRIDIS

Abstract

Morphological and histological observations have been made on the pre-anal glands of Hemidactylus flaviviridis. The glands are tubulo-acinar and present only in males. They are holocrine in nature and become hyperactive during the breeding period. It seems probable, therefore, that they have a socio-sexual function.
