" The pancreas consisted of two lobes united by an intervening 

 slip or narrow portion, through which passed an hepatic duct running 

 from the liver to the intestine. 



" The biliary and hepatic ducts entered the intestine a foot below 

 the stomach (gizzard) as follows : 



1st, Hepatic duct; 

 2nd, Pancreatic duct; 

 3rd, Cystic duct. 



" The intestines were thin and worm-like, their mean diameter 

 being -J-th of an inch. Their total length was 8 feet. 



" The vena porta ran close to the pancreas, and was dilated into 

 a large sinus before entering the liver. 



" The lining membrane of the gullet was thrown into longitudinal 

 plicee throughout its whole length, but they became larger and less 

 numerous towards the lower part, and the membrane itself increased 

 in toughness and density as it approached the proventriculus . The 

 muscular tunics consisted of an internal longitudinal and external 

 circular layer of fibres ; these fibres on the pouch were very fine and 

 delicate, but became stronger and more distinct as the gullet pro- 

 ceeded from this extensible portion. 



" The appearance and shape of the proventriculus were very re- 

 markable ; instead of its being a gradual dilatation of the gullet, it 

 commenced abruptly, and its parietes were firm and muscular, inso- 

 much that it might readily have been mistaken at first for a gizzard. 

 Its length, including that of the gizzard (which forms with it a com- 

 mon cavity), was 5 inches, and its circumference 4. The internal mem- 

 brane was puckered into longitudinal ruga, and was studded with 

 closely set glands of the size of large pin-heads. The longitudinal 

 muscular fibres were remarkably strong, and a muscular slip pro- 

 ceeding obliquely from the side of the gizzard attached the pyloric 

 enlargement to it. 



" The pyloric enlargement was about the size of a common gar- 

 den-bean. A passage 4ths of an inch in circumference and 4ths long, 

 turning up abruptly, led to it from the stomach. The lining mem- 

 brane of this passage was thrown into longitudinal folds. The lining 

 membrane of the pyloric cavity itself was thin, and not at all coria- 

 ceous, and the muscular tunic fine. A valvular fold encircled the 

 opening into the succeeding portion of the pylorus. 



" The testes were as large as peas, or rather larger, white and 

 oval. 



" The cervical vertebra were 15 in number. 



With reference to the bony union of the os furcatum to the sternum 

 observed in this Pelican, Mr. Martin remarks that " in the Adjutant, 

 Ciconia Argala, Vig., though the keel of the sternum is much more 

 extensive, deep, and strong, the os furcatum much resembles that of 

 the Pelican, and is in like manner ossified to its anterior apex. In 

 the common Heron, Ardea cinerea, Linn., the os furcatum is feeble, 

 but is also united by bone to the apex of the keel of the sternum : at
