rolled up upon itself in a circular form: then the intestine makes 

 another shorter turn upon itself, and afterwards goes to form the rectum. 

 There is no caecum. The liver is divided into two lobes. 



[So far, I examined the parts of a small East Indian dove, and found 

 them agree : this was a hen-dove : the following I could not observe.] 

 There is no gall-bladder. One of the biliary ducts enters the duodenum 

 within a | of an inch of the stomach. A pancreatic duct enters the 

 duodenum near the third turn. The situation and shape of the spleen 

 were as usual. The testicles were very large and close to one another. 

 The two peruses were just as in the common fowl. 



A White Dove. 



It had no gall-bladder, but two biliary ducts ; one veiy large, the 

 other very small : the large one enters the duodenum just in the first 

 turn, close by the gizzard, as in the Brazilian dove ; the small one enters 

 the duodenum about an inch before the last turn. The pancreatic ducts 

 enter at the last turn of the duodenum. By blowing into the large one 

 it fills up the small one, which dilates the duodenum. It has the cwo 

 small caeca, as in other doves. 



The Large Blue Crowned Pigeon, from the East Indies 

 [Lophyrus coronatus, Vieillot]. 

 The oesophagus is large between the mouth and the crop : the crop 

 is large, bulging out laterally as in the common pigeon 1 : the oesophagus 

 between crop and stomach is smaller and stronger in its coats than 

 the other. These divisions of the canal may be called ' oesophagus supe- 

 rior ' and ' inferior.' There are two rows of glands 2 arising from the 

 beginning of the lower oesophagus, and gradually losing themselves in 

 the oesophagus as they pass down. The gizzard is extremely strong, and 

 its horny lining is very strong at its two muscular ends ; it is furrowed 

 on its inner surface, and cross-furrowed with less deep grooves. The 

 duodenum passes out as usual towards the right, makes a bend down- 

 wards for 5 inches in length, and is then bent up upon itself as high as 

 the former : the intestine then leaves the duodenum at this first turn 

 downwards towards the back on the right, and passes behind the former 

 or duodenum, and may now be called jejunum, as it becomes a loose 

 intestine : this is about 8 or 9 inches in length, having a pretty broad 

 mesentery ; the termination of which loose part is at the root of the 

 mesentery, and thence it sets out, forming a long fold upon itself near 

 a foot in length, not above -|ths of an inch distant from one another : 

 this fold is united by cellular membrane loaded with fat ; besides which
