46 U.S. NATIONAL MUSEUM BULLETIN 221 



27103. Adult (sex not indicated). Hacienda "Mirador," State of Vera- 

 cruz, Mexico. 1861 or 1862. Collected by Carl C. W. Sartorius. 

 This name was based upon a series of 14 specimens, now known to be 

 referable to at least three races. The example here listed was long ago set 

 aside by Richmond as a lectotype, and Brodkorb (op. ciL, p. 1) accordingly 

 restricted the type locality of griseocauda to Mirador, Veracruz. By this 

 restriction the cotypes were reduced to two; the second, a female from Rio 

 Seco, Veracruz, is now in the Museum of Comparative Zoology, where it 

 is No. 77366.

 Ridgway, in the original description, mentioned ten specimens, but failed 

 to designate a type. This omission was remedied in the Proceedings of the 

 U.S. National Museum (8:579, Nov. 23, 1885), where under the name 

 Rupornis magnirostris gracilis, No. 102852 was stated to be the type.
