 (?) Sp.[inites'\ socialis Cabanis, Mus. Hein.,i, April, 1851, 133 (Mexico). 

 l^nzellal socialis Lichtenstein, Nom. Av. Mus. Berol., 1854, 43, part (Mexico). — 

 ScLATERand Salvin, Nom. Av. Neotr., 1873, 32, part. 



1 Eight specimens. 



^ Seven specimens, one of them with sex doubtful. 



'This specimen, in worn breeding plumage, I am unable to distinguish from Mexi- 

 can specimens. It seems probable, therefore, that S. s. pinetorum belongs to the more 

 eastern portions of northern Guatemala (departments of Vera Paz, Peten, etc.), and 

 extending thence southeastward across Honduras.
