across the breast, as all the evidence seems to point in that 

 direction. Secondly, that at Beverley, where Mr. Shortridge 

 procured three specimens, one is typical B. zonarius, with no 

 red band on the forehead and the whole breast yellow ; 

 a second is similar, but possesses a distinct red band across 

 the forehead ; while the third is a typical example of B. semi- 

 torquatus. It is evident that at Beverley the ranges of 

 B. semitorquatus and B. zonarius meet, and probably the 

 birds to some extent interbreed, which would account for 

 the intermediate forms to be found there. 



[The Yellow-collared Parakeet was very abundant in the 

 south-western division, but rare around Albany. Among 

 the colonists it is commonly known as the " Ring-neck " or

I have no doubt that B. occidentalis, a name given by 

 North to two specimens of Barnardius, procured at Roeburne 

 in the north-western division of West Australia, is synony- 

 mous with B. zonarius : the birds procured by Mr. Short- 

 ridge on the Gascoyne River agree well enough with 

 Mr. North's description, being also in worn plumage, but 

 they are most certainly referable to B. zonarius.
