Dr. J. Haast on the Extinct 
subdivisions, of which the largest size is the most conspicuous 
and best marked; so that the suggestion ventured concerning 
two subspecies belonging to Meionornis casuarinus and didi- 
formis applies equally to this remarkable extinct bird. 
The division between this and the next species, Patapteryx 
crassus, is well marked, consisting, moreover, of two con¬ 
stantly maintained sizes. 
Euryapteryx gravis and E. rheides , which can easily be dis¬ 
tinguished at a glance from each other, not only by their size, 
but by their anatomical characteristics, consist each of two 
sizes only, which, as I suppose, is to be attributed likewise to 
difference of sex. 
Amongst other species of extinct birds of which the Glen- 
mark turbary deposits have yielded remains, there is first the 
huge diurnal bird of prey which I described under the spe¬ 
cific term of Harpagornis moorei. Another remarkable species 
is a Ralline form of gigantic size, Aptornis, of which we have 
obtained sufficient material for articulation, and which is 
closely allied to Ocydromus, the Woodhen. 
The remains of Cnemiornis (a gigantic goose, as first 
pointed out by Dr. Hector) have hitherto been very scarce, 
so that we possess only a few bones of it. It is remarkable 
that the excavations, undertaken during a number of years, 
did not yield a single bone of Notornis , which, therefore, did 
either not inhabit this part of the country, or was of extremely 
rare occurrence. 
Of other species we have obtained bones oiApteryx, Strigops, 
Ocydromus,Himantopus, Botaurus, Hcematopus, several species 
of Ducks, and of a number of still smaller birds, which can¬ 
not be distinguished from bones belonging to recent species. 
The remarkable fringed lizard, Hatteria punctata, was also 
an inhabitant of this island, as several bones belonging to it 
were found with the Moa bones. 
Professor Owen having described at some length in several 
of his memoirs on Dinornis the affinities our struthious birds 
bear with those of other countries, pointing out at the same 
time the peculiarities through which they vary from them, it 
would have been unnecessary for me to add any thing to the
