304 GRALLATORES. 



is a little flattened, and when got near the thorax, leaves the neck and 

 passes on to the union of the two legs of the hone called ' merry- 

 thought,' under which it creeps ; likewise gets under the most promi- 

 nent part of the sternum, and follows the sweep of the end of that 

 bone; making a very quick turn, and is bent again round another 

 prominent part of the end of that bone, and then enters the thorax : 

 here it makes two complete turns like the Roman letter S. 



There is a cavity [air-cell] between the eye and the anterior part of 

 the orbit that communicates with the nose. This crane has a bursa 

 nigra [marsupium or pecten] as in other birds \ 



The Crane \_Grus cinerea, Bechstein]. 



The crane is blue, something like the common heron or demoiselle. 

 It has a strong gizzard, in which were stones, buttons, halfpence, tfcc. ; 

 the inner cuticle is firm. The duodenum makes its usual fold close 

 upon itself, then becomes a loose intestine, strung on the mesentery, 

 but not regularly so, for they make five loose folds in their way to the 

 rectum. The two casca are attached to the last fold ; they are about 

 4 inches long, and round at their blind ends ; then commences the 

 rectum. The liver is as usual : the hepatic and cystic ducts enter the 

 duodenum near together, and at the last turn of that gut, where it may 

 be said to terminate in the jejunum. The pancreas consists of a pair of 

 glands, one on each side of the mesoduodenum : the duct of the ante- 

 rior gland arises from the upper end of it and enters the gut with the 

 cystic duct of the liver : the duct of the posterior one passes out from 

 its middle, and enters the last fold of the duodenum about two inches 

 before its termination. 



The trachea is long, pretty small, and makes a turn in the keel of 

 the sternum for about two inches 2 . 



Of the Cyrus [or Serass] Crane [G?iis Antic/one, Ctiv.]. 



This crane has a pretty strong gizzard : I should imagine nearly as 

 strong as that of a goose, turkey, &c. ; it had stones in it, like the 

 above birds, and the contents were strongly tinged with bile, yet there 

 was nothing like bile in the duodenum. The gut makes the usual fold, 

 in which lies the pancreas : the other small intestines first make three

 ' Memoires pour servir a l'Histoire Naturelle des Animaux,' 4to, p. 334, that they 

 could not find the black sacciform membrane proceeding from the optic nerve, in 

 the Numidian demoiselle, as in other birds.]
