RAPTORES. 



[The Hen-harrier (Circus cyaneus, Bechst.).] 



In a hawk between the gos- and sparrow-hawks, having long, small, 

 yellow legs, and a head approaching that of an owl, with a yellow spot 

 [cere] at the root of the bill, there is a kind of crop, or a wideness in 

 the oesophagus, as in the goshawk. The viscera in general are as 

 in that bird. 



The Goshawk [Astur palumbarius, Bechstein 1 ]. 



The oesophagus is very large on the neck, becoming larger and larger 

 downwards ; this serves as a crop ; for there was a great deal of meat 

 in it, which the bird had eaten some hours before ; it then contracts at 

 once at the usual place. "Where the oesophagus begins again to swell, 

 then it is glandular, but the orifices of the glands are smaller than in 

 the [proven triculus of the] hen. The stomach is a good deal like that 

 of an owl ; it is oblong or pyramidal, beginning to swell as soon as it 

 is got below the diaphragm, and is largest at the lower end with a little 

 bend, and from the hollow of the bend passes out the duodenum. The 

 stomach is not very strong in its coats ; it has a middle tendon, but 

 not of a shining colour ; and the muscular fibres are white, not red like 

 those of a gizzard. The inside is rugous like the human stomach, and 

 is continued so into the duodenum for about half an inch, and there 

 the ruga; end at once. The food was the same in the stomach as in 

 the oesophagus. The duodenum makes the first turn, as in the common 

 fowl, and was filled with a white chyme. Then the intestines grow 

 loose, and, before they end in the rectum, they make a little turn on 

 themselves. The caeca are not above -|ths of an inch long. The rectum 

 is about 3 inches long, and opens into a large bag which is more than 

 an inch long, and about as wide. Its opening is like that of the os 

 tinea; into the vagina. Above the rectum there is a pretty large 

 cavity. The ureter passes into the rectum a little above the edge of 

 this cavity. 



The gall-bladder is round ; the ductus cysticus and ductus hepaticus 

 enter more than a | of an inch distant from each other ; the ductus 

 cysticus terminates further on in the gut ; and on the inside of the 

 gall-bladder there is a kind of groove passing between the cyst-hepatic 

 and cystic ducts. The pancreases are two, one before the common or 

 intermediate mesentery of the duodenum, the other behind it ; and 

 their ducts do not enter together or with the gall-ducts.
