NOVITATES ZOOLOOICAE XXIV. 1917. 501 



Coryphistera alaudina campicola Todd. 



In Proc. Biol. Soc. Washington xxviii. jx 170 (1915) W. E. Clyde Todd de- 

 scribed a specimen collected by Steinbach at Guanacos, Bolivia, under the above 

 name. We have a skin collected by the same field-collector at Yuay, provincia 

 Cordillera, South Bolivia, at an altitude of 450 m., which would seem to belong 

 to this new form ; the description of the upperside agrees, but we should rather 

 say that the underside was brighter and more boldly striped ; moreover, there 

 is a striking difference in the coloration of the tail, tlie outer four pairs of rectrices 

 having much more black than our five specimens from Tucuman, Argentina.
