MANUCODIA ATRA AND OTHER BIRDS.

Of Phonygama gouldi, the Australian representative of P. keraudreni, 

 I have been enabled to examine three detached tracheae, as well as three 

 entire birds collected at Cape York by H.M.S. 4 Challenger,' and kindly P.Z.S.^1882, 

 intrusted to me by the late Sir Wyville Thomson. The first three are 

 those already mentioned by Mr. Tegetmeier in his appendix to the 

 * Natural History of the Cranes ' *. All are convoluted, though that of 

 the female specimen is least so, and those of the two males vary slightly in 

 the amount of convolution. They very closely resemble that oiP.keraudreni 

 figured on p. 68, fig. 2, in the second of Prof. Pavesi's papers already quoted, 

 but have eight instead of nine folds, counting along a transverse line 

 drawn through the centre of the coil. Of the three ' Challenger ' birds, one 

 a female t, has a trachea with a single curved loop, like Pavesi's fig. 8, 



Trachea of Manucodia atra. 



whilst in the two others the trachea is quite straight, with no trace of a 

 curve. One of these is a male, probably young, whilst the other is an aduU 

 female, as shown by the oviduct containing an egg nearly ready to be laid. 



It is clear therefore that in this species, too, the female may some- 

 times have no tracheal loop at all. 



As regards the habits of P. gouldi, I reproduce here some extracts 

 from the notes accompanying the receipt of the first three tracheae 



* London, 1881, pp. 87,88.
