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 ,, 



The egg purchased in 1854 in the Paris Museum measures : — 

 Large circumference.... .... .... ... 925 mm. 



Small circumference .... .... 753 ,, 



In addition to these four eggs which are undoubtedly of Ae. titan, there 

 are the following which I consider to belong to that species : — 

 1 Paris Museum, Mr. Armange. 

 1 Hamburg. 



1 Messrs. Gilford, Orange, New Jersey. 

 1 Rowley collection. 



These four eggs range from 900 mm. to 863 5 mm. in large circumference, 

 and 770 mm. to 736 mm. in small circumference.
