oweni, in which the tibia measures only 9°2, the smallest. 4. parva 
is the only member of the Family of which there is a perfect 
skeleton in English collections. It is identified by Capt. Hutton 
with the typical 4. didiformis ; but a skeleton transmitted by Von 
Haast to the British Museum and assigned to the latter has a 
relatively smaller skull.1_ In the type of A. (Mesopteryx) didina the 
integuments of the head and feet are still preserved. 
Emeus, Reichenbach, was established on D. crassus, Owen. It isa 
rather large species, to which Owen and Von Haast assigned a broad- 
billed skull, and although Capt. Hutton states that the skull is 
really of the narrow-beaked type of Anomalopterya, we have reason 
to believe that the original view is correct. This Moa was confined to 
the South Island.

Von Haast proposed the name Luryapteryx for the small and 
broad-beaked D. gravis, Owen. This species, which is confined to the 
South Island, is distinguished from those that follow by the absence 
of any inflection of the lower end of the tibia, and the relative 
length and straightness of that bone. It therefore seems to be 
entitled to generic distinction.? If, therefore, the so-called D. 
crassus really have a broad-beaked skull, both that and the present 
species may be included under the title of Hmeus. 
Lastly we have the genus Pachyornis, Lydekker, likewise typi- 
eally confined to the South Island, and including some three or 
four species of large size, characterized by the extraordinary 
massiveness and sharpness of their limb-bones. The _ tarso- 
metatarsus (fig. 2, A) presents a remarkable contrast to the corre- 
sponding bone of Dinornis (fig. 2, B); and a similar contrast is 
1 Tt is doubtful if this skeleton is altogether authentic. 
2 According to Von Haast it is further distinguished by having a sternum of 
the type of Anomalopteryx, but Capt. Hutton throws some doubt on the correct- 
ness of the restoration of the skeleton by Von Haast.
