PACHYORNIS COMPACTA (HUTT.)
Euryapteryx compacta Hutton, Trans. N.Z. Inst. XXV, p. 11 (1893).
Approaches nearest to pygmaeus in size, but can be at once distinguished by the distal extremity of the tibio-tarsus not being expanded inwards. The tarso-metatarsus has the trochleae considerably more expanded than in pygmaeus.
Type from Enfield in New Zealand.

PALAEOCASUARIUS FORBES.
Dr. Forbes founded this genus of Dinornithidae on remains of Moas of three distinct sizes as regards femora collected by him at Manitoto. Dr. Forbes has kindly placed these bones at my disposal, and the following summarises the results of my examination. I find that Dr. Forbes' original idea as to the distinctness of Palaeocasuarius is perfectly justified, as not only are his characters of the tibio-tarsus, as opposed to those in the other genera, correct, but the proportions between femur, tibio-tarsus and tarso-metatarsus are quite different to those of other genera. I give the proportions of the three bones in Palaeocasuarius elegans, Megalapteryx tenuipes, and Pachyornis elephantopus, which are the three most nearly allied genera:
| Pal. elegans. | M. tenuipes. | Pach. elephantopus. | |
|---|---|---|---|
| Femur, length | 10⅝ inches | 110 inches | 120 inches |
| Width over condyles | 03½ inc" | 03½ nc" | 05 ½nc" |
| Tibio-tarsus, length | 16 ½inc" | 15½ nc" | 33 ½nc" |
| Width at distal end | 02 ½inc" | 02¼ nc" | 03½ nc" |
| Tarso-metatarsus, length | 07 ½inc" | 06 ½nc" | 09 ½nc" |
| Width at centre | 01½ inc" | 01¼ nc" | 02¼ nc" |
