Duvernoy's gland
WebDuvernoy's glands in the Homolopsinae form a gradually enlarging series, with the largest glands found in Enhydris. The variation of the histological pattern in the Duvernoy's glands of the Colubridae clearly opposes the view that the Boiginae (Dipsadomorphinae of authors) are a natural group. WebMost detailed analyses of Duvernoy's secretions and their biological properties have been performed since the late 1970s. The dispholidines, Dispholidus typus and Thelotornis sp., and the natricines, Rhabdophis tigrinus and R. subminiata, have received the most attention due to the high toxicity of their secretions and their medical importance.
