“This bone in Zpyornis shows a flat, full, oval articular facet on 
its tibial side, of which there is no trace in Dinornis. 
“Upon the whole, therefore, Professor Owen concluded that the 
Zpyornis maximus did not surpass in height or size the Dinornis 
giganteus, and that it was more probably a somewhat smaller bird. 
“The fragments of the egg of Dinornis or Palapteryx—of what 
species of course cannot be determined—show, after arriving approxi- 
mately at their size by a curve of the fragments, that the shell was not 
only absolutely thinner, but relatively much thinner than in the ostrich, 
and @ forliori than in the Zpyornis. The air-pores, also, have a 
different form, being linear not rounded, and the external surface is 
smoother. 
“ In the smoothness and thinness of the shell, the egg of the Dinornis 
_resembles that of the Apteryx; in the thickness of the shell and the 
comparative roughness of its exterior, the egg of the Zpyornis more 
resembles that of the ostrich and cassowary. 
“Jt is most probable that the entire eggs of the Aipyornis were 
excluded in the usual fertile state, but had suffered such want or inter- 
ruption of the usual heat requisite for their incubation as to have 
become addled.”

The Recent Moa. 
Ar the meeting of the Linnean Society of London, held on the 17th 
of June, my friend Thomas Allis, F.L.S., and Vice-President of the 
Yorkshire Philosophical Society, exhibited some of the bones of the 
moa, together ‘with two beautiful photographs by Monkhouse and Co., 
of Pendall, York, and read a paper descriptive of the bones, and the 
circumstances under which they were found, including suggestions as 
to their probable age. The first plate exhibited the following bones :— 
the sacrum, three vertebra; normally anchylosed, and having the left 
ribs attached; one other vertebra with attached rib; the sternum with 
its second and third right ribs, and its second left rib still attached ; 
a fibula with a portion of the outer skin still attached; the left inner 
toe, with the sole still adhering, and a portion of the sole of the foot 
also attached; the head, which is perfect with the exception of the
