Show 1899.] INTERNAL ANATOMY OF NOTORNIS. 91 The gizzard and duodenum were filled with short pieces of sedge ( Garex) and Uncinia. The liver-lobes present the usual inequality. The gall-bladder is an oval sac, completely outside and free from the liver; there are the two usual ducts, one the " cystico-enteric," the other the " hepato-enteric." The pancreas is provided with two ducts, one from the dorsal lobe and the other from the ventral lobe, as w e may term those parts which lie on each side of the mesentery, as the duodenum lies spread out in the normal Avay, though no doubt right or left would be more appropriate. The ventral lobe of the pancreas terminates anteriorly in a freely projecting finger-like process. Both the ducts arise at the hinder end of the pancreas, pass directly across the mesentery, to open close to the two liver-ducts into the distal limb of the intestine (fig. 1, I, g, p). (b) The Tongue (fig. 2).-The acute tip of the tongue is beset with a series of short brown cylindrical horny spines (s), which Fig. 2. A.

At the base of the tongue is a transverse, slightly curved ridge, beset with a series of fourteen hard, conical, white papilla? (c) or |
