Plate 3 



A toad in process of being swallowed by a green grass snake (otherwise known as the green 

 keelback, M acropisthodon plumbicol'or). The snake alternately advances the right and 

 left sides of its upper jaw, obtains a purchase with its teeth and draws the toad into itself, 

 or, rather, slips itself over the toad. The swallowing occupies about an hour, and di- 

 gestion has probably begun on the head before the hind legs disappear. (Photographs by
