14th February, 1893. — The Secretary read a report on the additions 
that had been made to the Society’s Menagerie during the month of January 
1893. — Prof. G. B. Howes, F.Z.S., exhibited and made remarks on an 
abnormal sternum of a Marmoset (Hapale iacchus) in which the mesosternal 
elements of the opposite sides were distinct, and alternately disposed, and 
discussed its probable bearings upon the sternum of the Anthropomorpha, 
particularly as represented by the Orang. — Prof. T. Jeffrey Parker, F.R.S., 
read a paper on the cranial osteology, classification, and phylogeny of the 
Dinornithidae. The author gave a detailed description of the skull in various 
genera and species of Moa, founded upon the examination of more than 120 
specimens. A detailed comparison with the skulls of the other Ratitae 
followed, as well as an extensive series of measurements. 
The bearing of the facts ascertained upon the classification of the family 
was discussed. The author recognized five genera of Dinornithidae, arranged 
in three subfamilies as follows: 
Subfamily Dinornithinae. 
Genus Dinornis. 
Subfamily Anomalopteryginae. 
Genera Pachyornis, Mesopteryx, and Anomalopteryz. 
Subfamily Emeinae. 
Genus Emeus. 
The phylogeny of the group was then discussed. Mesopteryx was con- 
sidered to be the most generalized form, while Dinornis and Emeus were both 
highly specialized, but in different directions. Of the other Ratitae, Apteryx 
came nearest to the Moas in the structure of its skull, and strong affinities 
were shown to the New Zealand genera by Dromaeus and Casuarius. Struthio 
and Rhea, on the other hand, showed no special affinities, so far as the skull 
is concerned, either to the Australasian forms or to one another. — Mr. R. 
Lydekker, F.Z.S., read a paper on the presence of a distinct coracoidal 
element in adult Sloths, and made remarks on its homology. It was shown 
that in two skeletons of Sloths in the British Museum the shoulder-girdle 
exhibited a distinct coracoidal element. This element, like the coracoid 
process of the human scapula, was correlated with the precoracoid of the 
lower vertebrates; and the question was then discussed as to the name by 
which it should properly be called. — A communication was read from Dr. 
G. Radde, C.M.Z.S., containing an account of the present range of the 
European Bison in the Caucasus. — P. L. Sclater, Secretary.
