MANUCODIA ATRA AND OTHER BIRDS. 343 



of Pipile cujubi and Notliocrax urumutum have yet been examined : these 

 had simple tracheae ; and the same is the case in both sexes of Aburria 

 carunculata.~\ 



B. The trachea has a considerable superficial loop in the cervical 

 region, anterior to the thoracic muscles. 



Fam. 

 Tetrao urogallus. The male only, apparently. 



C. The trachea has a loop entering into, and enclosed by, a bony cavity 

 formed by the clavicular symphysis. 



Fam. NUMIDID^E. 



The Guinea-fowls of the genus Guttera, as seen in both sexes of -P- Z. S. 1882, 

 Guttera cristata and G. pucherani. The same conformation occurs in ^' 

 G. eduardi ; but the sex of my specimen is not, unfortunately, recorded. 



[In Numida proper (N. meleagris, ptilorliyncha, and mitrata have been 

 examined), as well as in Acryllium vulturinum, the trachea is quite 

 simple in both sexes.] 



D. The trachea has several intraihomcic convolutions. 



Fam. CICOKTIDJE. 



Tantalus ibis, in the male (cf. Garrod, Coll. Papers, p. 286). 



[The condition of the female is unknown.] 



[In both sexes of T. loculator, as well as in the females of T. leuco- 

 cephalus (the other sex not yet having been dissected) the trachea is 

 unconvoluted.] 



Fam. LBIDID^J. 



Platalea leucorrodia. <$ . ( $ , Mtzsch.) 



[In Ajaja rosea the trachea is known to be simple in both sexes, though 

 the bronchi are peculiarly long. Cf. Garrod, 1. c. p. 288.] 



E. The trachea is convoluted, the convolution impinging on, or 

 entering, the carina sterni. 



Fam. CYGiaDJs. 



In the Swans of the Cyynus ferus group, the trachea, as has long been 

 known, has a number of intrasternal convolutions, which may extend to 

 near the end of the bone.
