_Aepyornis titan_ Andrews, Geol. Mag. 1895, p. 303.
This appears to be the largest species of the genus, though _Ae. maximus_
is considerably stouter. In the original description of _Ae. ingens_,
however, the tibio-tarsi referred to that species are really those of _Ae.
titan_:--
Smallest Femur.
Length about 430 mm.
Circumference, narrowest point 280 "
Width, distal end 190 "
Width of shaft at narrowest part 97 "
Largest Femur.
Length 470 mm.
Circumference at narrowest point 280 "
Width, distal end 210 "
Distal part of tibio-tarsus.
Width at distal end 180 mm.
Width of shaft at narrowest point 77 "
Circumference of shaft at narrowest point 210 "
Tarso-metatarsus.
Length 480 mm.
Width at proximal end 190 "
Width at distal end 165 "
Width at narrowest point of shaft 80 "
Circumference at narrowest point of shaft 200 "
{224}
The skull, pelvis, and most vertebrae, as well as the sternum of this form
are unknown.
Habitat: S. W. Madagascar.
Three Femora, two tarsi-metatarsi, and two incomplete tibia-tarsi are in
the Tring Museum, collected by Last in the Antinosy country.
There are two eggs of this species at Tring, the measurements of which are
as follows:--
No. 1, Antinosy Country, Last.
Large circumference 862.5 mm.
Small circumference 631.5 "
No. 2 (traded).
Large circumference 883 mm.
Small circumference 763 "
The egg mentioned by Mr. Lydekker in Cat. Foss. Birds B.M., page 214, No.
41847 is, judging from its size, undoubtedly an egg of this species, and I
quote the measurements, as they are very large:--
Largest circumference 921 mm.
Smallest circumference 768 "
