thick symphysis, where it coalesces with its fellow to form a broad external symphysial 
prominence (32), measuring 7 lines across the back or lower part and 9 lines across the 
upper border. The length of the symphysis is 1 inch 3 lines. The upper border of 
the dentary swells outward, increasing in depth as it approaches the symphysis, the 
surface of which is perforated by the numerous nutritious vessels of the matrix of the 
horny beak, the thinner hind part of the dentary being smooth. The alveolar border 
(Pl. LXIII. fig. 4, 6) is impressed by a shallow groove. 
The premaxillary (Pls. LXII. & LXIII. fig. 1,22) is very broad, depressed, with the 
usual triradiate division posteriorly ; the upper ray (PI. LXII. fig. 1, 22") is a backward 
continuation of the middle raised part of the body of the bone, which expands transversely 
and becomes flattened from above downwards as it extends backward to rest upon the 
nasal fossa (15); the sides of this process, before it quits the body of the bone, are 
concave, as it were pinched in; the least breadth of the upper part of the process is 
6 lines. The maxillary processes (22") are short; both, however, are broken: the 
breadth of the palatal part of the premaxillary (PI. LXIII. fig. 1) is 3 inches; it has a 
small posterior emargination, on the under surface of which is a canal leading forward 
jnto the bone: on the upper surface are three similar orifices, also leading forwards. 
The upper or nasal surface of the plate (22") of the premaxillary shows a shallow 
posterior excavation for the support of the palatal part of the maxillary. The alveolar 
borders of the premaxillary show a shallow multiperforate broad groove (b). 
After having written ‘the foregoing description of the parts of the ‘skull of the 
Dinornis robustus, from ‘Timaru,’ and bad the Plates LXII. and LNXIII. executed, I 
received the following letter, dated “Dunedin, 15th February, 1864,” from Dr. Hector, 
F.G.S., the accomplished and efficient Provincial Geologist of Otago, New Zealand, 
informing me of the discovery of ‘ an unusually perfect skeleton of a Moa,” which 
had been “recently found by some gold-diggers in the interior” of that province. 
“The skeleton,” he writes, “was not that of one of the largest-sized Moas, the 
tibia, for instance, being only 27 inches in length, whereas I have frequently seen 
them as much as 36 inches.” This skeleton Dr. Hector proceeds to describe ‘‘as the 
most perfect [ have ever heard of, as all the bones, excepting five or six, are present ; 
and it is further, I believe, a unique specimen in so far that portions of the integu- 
ments and feathers still remain attached to the sacrum. There js also a portion of 
the sole of the foot; and the joints of one leg have their ligaments and interarticular 
cartilages preserved.” 
Dr. Hector then proceeds to give the following instructive and valuable account 
of the geological characters of the locality and district where the discovery was 
made :—
