_Aepyornis hildebrandti_ Burckhardt, Pal. Abh. (VI) II, p. 127 (1893).
I must refer my readers to Dr. Burckhardt's description, as it is too long
and too technical to be reproduced here, especially as it is not
comparative. I, however, give here some of his measurements:--
_Tibio-tarsus._
_A. grandidieri._ _A. hildebrandti._
Length 640 mm. 480 mm.
Breadth at proximal end 190 " 130 "
Breadth at distal end 135 " 82 "
_Tarso-metatarsus._
Length circa 375 mm. 275 mm.
Breadth at proximal end 145 " 103 "
Breadth at distal end 145 " 95 "
The locality of the type is Sirabé.
Habitat: Madagascar.
