 (V) Bolivia has the wina 18 in., and if this is a migrant from Mexico, there 

 may be a large northern race, and if so it could be called mexicanus. 

 Gray's aJbonotatus (Mexico) is a nominuin nuclem and cannot stand, while 

 Kaup's albonotatus (Isis, 1847, p. 954) is neither a name nor a description. 

 His albonotatus in Contr. Orn. 1850, p. 75, is from " S. America " and is based 

 on the " concealed white spots," which can be seen on the Surinam bird at 

 Tring, and not on the Mexican ; they appear only to mark a stage of plumage. 

 The only certain distinction seems to lie in the relative sizes.
