Garrulus sordidus Sw. 



Bullock Mexico 



There is a size discrepancy between Swainson's 

 original description (Philos. Mag. N. S. 1, J\me, 

 1827, A37) and his more detailed account (Zool. 

 niustr. 2, Series 2, 1832, pi. 86 and text) 

 published five years later. In the first he gives 

 "total length, 11 inches; bill, 1-1/^5 wings, 6-1/2; 

 tail, 6-1/2; tarsi, 1-1/2". In Zool. niustr. he 

 gives "Total length, IK in.; bill, 1-1/2; wings 7; 

 tarsi 1-7/10; tail, (:>-1j2 in." Since even in the 

 later publication he is specific about having only 

 one specimen theii^ cannot be more than a holotype. 



"The Garrulus sordidus inhabits the table land of 

 Mexico from whence our specimen was received". 



The Cambridge specimen!^ suppl^measurements 

 almost exactly as given by S^wainson in ZoOl. Illustr. 

 and is unquestionally the type. It is filled. v/ith 

 stuffing which is not usual with Bullock skins, - 

 hov;ever the specimen is otherwise "Bullock". 



Very dirty below - hence " sordidus ". Typical 

 of the race now known as sieberii (iVagler) this 

 latter becoming a synonym of sordida and potosina 

 Nelson being resurrected. 



Remarks: Fresh winter plumage - probably a male.
