APHELOCOMA SIEBERII COLIM.ffi Nelson. 

 COLIMA JAY. 



Similar to A. s. sieberii, but slightly smaller (except bill), and some- 

 what lighter colored, especially the under parts, which are more 

 extensively white posteriorly and of a more brownish, as well as 

 lighter, gray anteriorly; the blue of a more cerulean hue, as in A. s. 

 potosina. 



Adult mafe.—Length (skins), 317.5-325 (321.5); wing, 176-180 (178); 

 tail, 158-160 (158.5); exposed culmen, 26.5-29 (27.5); depth of bill at 

 nostrils, 10.5; tarsus, 43-44 (43.5); middle toe, 23.5-25 (24).'^ 



1 0yanodita ultramarina oi SMmichrast (Mem. Bost. Soc. N. H., i, 1869, 554) seems 

 to be A. unicolm-, since the latter name is omitted from his list, while the present 

 species is given as C. sordida. ^ 



6 According to Schlegel (Mus. Pays-Bas, Coraces, 64), the specimen figured is the 

 type of Pica sieberii Wagler. 



"Three specimens.
