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.

AEPYORNIS MAXIMUS GEOFF.

Aepyornis maximus I. Geoffrey St. Hilaire, Ann. Sci. Nat. sér. 3, vol. XIV, p. 209 (1851).

Aepyornis ingens Milne-Edwards & Grandidier, C.R. CXVIII, pp. 122-127 (1894).

This is the stoutest and bulkiest species, though not so tall as Ae. titan. All the largest eggs next to those of Ae. titan must belong to this species. It will be argued that I have no right to use the name maximus for this form, but the name of maximus is based on one of the eggs in the Paris Museum, and as these evidently belong to this form and not to the form subsequently called maximus, I must apply to that the name of grandidieri, given by Mr. Dawson Rowley in 1867 to a portion of eggshell of the lesser form.
