auricle by tvvo large veins. The blood from the lovver parts and 

 viscera is brought by a large vein or vena portce into the liver, from 

 which organ a sinus emerges, of considerable circuniference, and 

 half an inch long, vvhich enters, or rather seems to forra a part of, 

 the right auricle. 



" The trachea is long, and divides at six inches from the rimą 

 into two branches, as already noticed, vvhich are about an inch and 

 a half long, and are again subdivided ; round the upper of which 

 subdivisions, as has been stated above, the aortcB are turned. The 

 rings of the trachea are entire ; the rimą small and simple. 



" The cesophagus is wide and membranous. The stomach is firm 

 and muscular : its circumference does not much exceed that of the 

 intestines, and its increase ai the cardiac, and diminution at the 

 pyloric portion is gradual. The intestines are, as in all these ani- 

 mals, very firm. The spleen is small, dark-coloured, and oval. 



" The liver is large, and consists of tvvo lobes, in the right of 

 which, on its under surface, the gall-bladder lies deeply imbedded. 



" The lungs consist of two lobes, extending along the cavity of 

 the chest, and attached to its dorsal aspect. They are composed of 

 an aggregation of minute delicate membranous cells. 



" The chest is divided from the abdomen by a partial membranous 

 diaphragm attached to the parietės of the abdomen by numerous 

 strings or filaments. 



" As compared with that of the chest, the cavity of the abdomen 

 is very small j the former occupying fuUy two-thirds of the length 

 of the body. 



" The liver lies in the abdorainal cavity, and just belovv the dia- 

 phragm ; and through this, covered by a reflexion of it, passes the 

 iinus emerging from the liver to the auricle. 



" The individual examined was a female, and the ovaries were seen 

 follovving two veins along the mesentery for the length ofnearly 

 tvvo inches."
