Natural history of two monotypic snake genera of southwestern Australia, Elapognathus and Rhinoplocephalus (Elapidae).

Provides data on body size, sexual size dimorphism, reproductive biology and food habits of Elapognathus minor and Rhinoplocephalus bicolor. The former has litter sizes of 8-12, is diurnal and eats skinks and frogs; the latter has litters of 1-5, is crepuscular (usually remaining within stick-ant nests, which are warm and dry) and eats only skinks. -P.J.Jarvis
