small species of the Locust tribe ; one Elater ; and one Spider, quite perfect ; with a few 
hard seeds and small pebbles’. There was also some muddy fluid loaded with the black 
particles of the earth probably swallowed along with some of the insects. ‘The small 
intestines contained portions of insects floating in a larger quantity of the black fluid : 
the ceca were distended exclusively with a thin blackish-brown pulpy fluid, in which 
only extremely minute portions of the legs of insects could be detected. 
The liver, in the larger male Apteryx, weighed 7 drachms, 35 grains, avoirdupoise ; 
it consisted, as usual, of two large lobes, connected by a narrow isthmus, with their thin 
anterior edges advancing forwards on each side of the proventriculus, and meeting in 
front and a little to the left of the middle line. The right lobe* is the longer, of a sub- 
triangular figure ; the left* is of a subquadrate form. The two lobes are even and smooth 
on their posterior and outer surfaces, but present irregular furrows and projections on 
their inner surface. ‘They are traversed here transversely by a broad portal fissure oc- 
cupied by the vessels and ducts. In two of the specimens there was a gall-bladder, 
as in the Hmew and Cassowary ; in the third it was wanting, as is usually the case with 
the Rhea and Ostrich. In the large male the gall-bladder adhered by its whole length 
to the omental process covering the stomach; in the other Apteryx it was free, and 
depended by its cervix from the inner margin of the right lobe of the liver; in this 
specimen’ it was an inch and a half in length, and received two short cyst-hepatic ducts 
at its cervix, each nearly a line in diameter: these ducts, with the serous membrane 
reflected upon them, and the nutrient vessels of the gall-bladder, formed the only me- 
dium of connexion between the gall-bladder and the liver. A cystic duct was conti- 
nued, in length rather more than two inches, to half-way between the lower bend and 
the termination of the duodenum. The hepatic duct is formed by two branches, one 
irom each principal lobe, which unite together to the left of the cystic duct ; it runs 
parallel with, and terminates a few lines below the cystic: both ducts are longer than 
usual. The lining membrane of the gall-bladder presents chiefly longitudinal ruge, 
with smaller transverse lines in the interspaces. In the Apteryx without a gall-bladder 
there were two long ducts terminating in the same part of the duodenum ; of which the 
one corresponding to the cystic (PI. V. 0, fig. 1.) was very slightly dilated at its origin, 
where it was formed by the confluence of two ducts. 
The pancreas (Pl. IV. & V. q, fig. 1.) consisted, as usual, of two elongated subtrihe- 
dral lobes, lodged chiefly in the anterior part of the duodenal interspace. One of the 
lobes extended upwards and to the right as far as the spleen. The secretion was carried 
by two short and thick ducts, which terminated, close to the hepatic and cystic, and 
alternating with them upon a small longitudinal ridge of the duodenal lining membrane. 
The spleen in one Apterye was about the size and form of a hazel-nut (Pl. 1V. r,) ; in 
the large male with the full stomach it was smaller and flatter: it was round, and an
