472 MR. A. H. GARROD ON THE AUSTRALIAN BUSTARD. [June 16, 



made me doubt the correctness of Dr. Murie's inference, that, be- 

 cause the neck of Eupodotis australis becomes distended much during 

 the sexual season, therefore there is a gular pouch. 



This individual bird, which formed the subject of Dr. Murie's

 projecting backwards, and not forwards as usual. 



The oesophagus and trachea of the specimen of Eupodotis australis here 

 described. The oesophagus is much dilated, and, like that of the Pouter 

 Pigeon, can be distended with air by the living bird. No trace of a pouch 

 or crop is to be seen. 



There was no gular pouch. There was no sublingual orifice. The 

 frenum linguae was well developed, it being necessarily quite absent in 

 the adult male of Otis tarda. How unsafe therefore is it to infer 

 that, because the neck distends and depends during the "show-off," 

 there must be a sublingual pouch. It is quite possible that two effects,
