DESCKIPTION OF A NEW SPECIES OF PARRAKEET — NORTH. 83 



by the different boats of the Continental Shipping Companies, would 

 tend to strengthen the opinion that the specimen is an escaped cage- 

 bird, but unless it has moulted since it obtained its freedom, the 

 perfect condition of plumage it is in points to the contrary. 



The specimen has been mounted and placed in the Collection, 

 where it will be available for future reference ; but for want of 

 further proof it is undesirable at present to include it in the 

 Australian avifauna.
