22 Mr, W. A. Forbes on the late Professor Garrod's 



In a preceding paper"^ Prof. Garrod has described and figured 

 the tongue of Nestor, which^ as he shows^ is peculiar^ and not 

 like that of the Lories, with which it has often been associated. 



6. Otidid^-f. — In Eupodotis australis there is not, as had 

 been supposed, and even stated J, by previous observers, a 

 gular pouch, such as has been seen in Otis tarda. On the 

 contrary, the oesophagus is highly distensile, and so produces 

 the singular appearance of the males of this bird when excited 

 during the breeding-season. In a young male specimen of 

 Otis tarda examined, there was also no gular pouch present ; 

 but the frcenum linguae was double ; and it is suggested that 

 the pouch which has been found in the males of that species 

 is due to a rupture and distention of the mucous membrane 

 between this duplicate frsenum, owing to the inflation of the 

 air-passages during the period of display. 



7. Chauna^. — The pterylosis, visceral anatomy, myology, 

 and cranial and other characters of the Derbyan Screamer 

 are here fully described. The very peculiar nature of the 

 alimentary canal, in the glandular parts of the proventriculus 

 forming, not a zone, but a patch, as well as in its possession 

 of long sacculated cseca, without any spiral valve, which open 

 into a special division of the intestine situated between the 

 colon and the ileum, is particularly worthy of notice, Chauna \\ 

 being absolutely unique amongst birds in this combination of 

 characters. In its pterylosis and syrinx, too, it is very 

 peculiar. As a result of his examination. Prof. Garrod con- 

 cludes that the Palamedece cannot be placed amongst the 

 Anseres, as had been done by Professors Parker and Huxley,
