216 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, Palapteryx 

 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, HcBmatopus, 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
