eniaciation has been present in other parts. The anatomical struc- 

 ture of the abdoaiinal viscera, for the raost part, agreed with the 

 šame in the tribe oi' Jntelopesin general. 



" The kiiineys vveie healthy, and were rather larger than is usual, 

 while the bladder vvas veiy small. The renal capsules were of an 

 oblong figure, and situated about half an inch anterior to the kid- 

 neys. 



" The tendinous portion of the diaphragm was very extensive, 

 and most beautifuUy developed, having nearly the appearance in 

 colour of the tapetum lucidum of the eye. The substance of the lungs 

 vvas hepatized, and there were in many parts adhesions to the in- 

 ward surface of the ribs. The right lung consisted of four lobes, 

 the left of three. The right side of the heart was peculiarly flaccid, 

 and the blood found in both sides was very dark in colour, and had 

 not undergone coagulation. The vena azygos passed upon the 

 left side of the spine. and terminated in the anterior cava: I have 

 observed a similar disposition in the Sheep and Chamois, but in the 

 latter animal the termination vvas in the posterior cava." 



A stufFed specimen vvas exhibit«d ofa female of the harnessed 

 Jntelope, Antilope scripta, Pall., vv'hich had lived for some months 

 in the collection of the Zoological Society of Dublin, by vvhoni it 

 vvas presented to the Society. 



Preparations were exhibited of the iracheez of the Penelope Gttan 

 of M. Temminck, and of the Anas Magellanlca, Auct.j and Mr.Yar- 

 rell read the foUovving short descriptions of them. 



" The trachea of the Guan is uniform in size and substance 

 throughout its \vhole length. After descetfding by the neck in the 

 usual way, it is extended and passes dovvnvvards under tlie skin, but 

 over the outer surface of the pectoral musele on the right side, to 

 the extent of 2 inches beyond the angle formed by the junction 

 ofthetvvo ^lOTŪons oi Ū\e os fiircatorium. The tube of the trachea 

 is thon reflected, and ascending to the cavity of the tliorax, again 

 turns to be carriad to the lungs as in other Birds, and is previded 

 vvith one pair of true museles of voice, \vhich have the usual origin 

 and insertion. The loop or fold of the tube formed on the surface 

 of the pectoral musele is imbedded in cellular tissue, and further 

 retained in its place by a strong ligament, which firmly adhering 

 to ihe loop, passes backwards to be first attached to the posterior 

 angle oi the sternum, and afterwards dividing once, and passing still 

 further backvvards, the two slips are inserted on the tvvo elongated 

 pubic points of the pe h is. 



" This structure in the Guan has been noticed and figured by 

 M. Temminck, in bis ' Histoire des Pigeons et Gallinacės,' but this 

 is the first opportunity that has occurred of exhibitinga preparation 

 fVom the bird on the table of the Society. 



" The trachea of the malė Magellanic Goose is furnished vvith a 

 large hollovv bony piotuberance on the left side, near ihe bottom of 

 the tube, at the point of divarication, similar in character to those 

 observed in the ivading Ducks, but diffcring in its form. ri\e dorsal
