110 THE ANATOMY OF THE HUIA BIRD.. : 
16. NOTES ON THE ANATOMY OF THE HUIA BIRD | 
(HETERALOCHA GOULD1).* 
A LivinG specimen of Heteralocha gouldi (Neomorpha gouldi, Gould, B. 
of Australia, IV. Pl. xix) was obtained by the Society on May 11th, 
1870, as was announced by Mr. Sclater in the “ Proceedings,” 1870, 
p. 388. It died on the 28th of February, 1872, in a much emaciated 
condition, but without organic disease. 
The following notes relate to its anatomy, and may, I trust, assist 
in enabling its affinities to be more easily determined. 
Pterylosis—The arrangement of the feathers is completely passerine. 
The rhombic saddle of the spinal tract does not enclose any ephippial 
space, therein differing from the Crow’s and resembling the typical 
Starling’s. There are nineteen remiges, of which ten are on the 
hand ; they increase in size up to the fifth. The rectrices are twelve 
in number. The oil-gland is nude. 
Tongue.—Simple, horny, one-third the length of the beak. It 
forms a flat elongated triangle, slightly bifid at its apex, and a little 
prolonged backwards at its lateral borders, enclosing a curved line 
for the base, the concavity being backwards and carrying retroverted 
papillee. 
The mucous membrane of the palate extends forward as far as 
the middle of the tongue; that of the mandible goes a little further. 
At the angles of the mouth, just below the eyes, are two yellow 
oval cutaneous expansions, fixed in front and free at their borders else- 
where; they appear as if they were prolongations outwards of the 
mucous membrane of the angles of the mouth, which had been reflected 
backwards—they being continuous in front, round the margins, with 
the mucous membrane. 
Syring.—As in Corvus and most of the Old-World Passerines. 
Intestines —The gizzard is well developed. The intestines are 16 
inches long, with the bile-ducts 24 inches from the gizzard. The 
ceca are one inch from the cloaca and + inch long, being cylindrical. 
Arterial System.—There is one carotid artery, the left. 
Foot.—The hind toe is slightly longer than the middle anterior toe. 
In arrangement the tarsal scutes are similar to those of Corvus and 
most Passerines. Their colour is blue-black. 
Skull.—The palate (Fig. 2) is strictly sgithognathous; that is,
