Sexes similar, juveniles unknown.


Formerly on Nosy Boraha (Ile Sainte-Marie), a small island off northeast Madagascar.
Almost certainly extinct. Last reported in 1834. It's uncertain if the species ever occured on mainland Madagascar.


This is a monotypic species.


Presumably restricted to primary forest near sea-level. Disappeared after deforestation of island.


Diet used to be large forest snails. They were obtained by breaking the snail against a stone anvil with its bill.
No information about breeding.
Presumably a resident and sedentary species.
