3. Note on a new Locality of Dinornithide.

[Received February 1, 1875.] 
I have been favoured by an esteemed correspondent, Dr. Cough- 
trey, with the following notice of a discovery in, to me, a new 
locality, in the province of Otago, New Zealand, of remains of 
Dinornithide. He writes :—‘‘ It might, perhaps, interest you to 
know that we got in the Hamilton Swamp remnants of the following 
species :— 
“© Dinornis maximus. Dinornis didiformis. 
robustus. casuarinus. 
—— ingens. crassus, 2 varieties. 
—— struthioides. elephantopus, 2 vars. 
—— rheides. gravis. 
“Of all the above species we have duplicate leg-bones. Besides, 
we have almost complete skeletons of ‘ Cnemiornis calcitrans.’” 
It is satisfactory to find that the authorities in charge of the 
rapidly rising museum of Otago appear to have no difficulty in di- 
stinguishing the remains of Dinornis gravis from the varieties referable 
to Dinornis crassus, my chief difficulty and, for some time, doubt hav- 
ing beenin relation to the limb-bone characters of the former species. 
Its cranial characters, however, were decisive ; and as the number of 
skulls of Dinornithidee now on hand corresponds with the species, 
or established varieties, of Dinornis, based on characters of the pre- 
viously found leg-bones, and as the descriptions and figures of 
these bones in the ‘ Transactions of the Zoological Society’ evidently 
serve their purpose in aid of the recognition of parts of the skeleton 
by their discoveries in new localities of New Zealand, one aim of the 
series of ‘“ Memoirs” which the Society has favoured me by 
publishing has been attained. 
4. On Anomalurus, its Structure and Position.

(Plate XXI.) 
This genus was established by Mr. Waterhouse in 1842*, and 
now contains four or five species, all natives of Tropical Western 
Africa. In external appearance the Anomalures very closely re- 
semble the larger Flying Squirrels (Pteromys)—their most striking 
outward distinctions being the double series of large salient scales on 
the lower surface of the first third of the tail, and the fact that the 
cartilage which serves to extend the flying expansion has its origin 
at the elbow instead of at the wrist. They are also described as
