VII. DESCRIPTIONS OF SEVENTEEN NEW 

 NEOTROPICAL BIRDS. 



By YV. E. Clyde Todd. 



Through the activities of Messrs. M. A. Carriker, Jr., and Jose 

 Steinbach the Carnegie Museum has acquired during the past three 

 years more than six thousand specimens of birds from South America. 

 The collections forwarded by Mr. Carriker came from Venezuela 

 (various localities in the valleys of the Orinoco, lower Caura, and 

 upper Cuyuni Rivers, and in the State of Lara), the islands of Trinidad 

 and Curacao, and the district of Santa Marta in Colombia. The 

 collections received from Mr. Steinbach are nearly all from eastern 

 Bolivia (Santa Cruz de la Sierra and Puerto Suarez). This material 

 is being studied as rapidly as circumstances permit, and it is expected 

 eventually to publish full lists, with critical .notes and the field obser- 

 vations of the collectors. In the course of these investigations a 

 number of apparently new forms have been detected, and it has 

 seemed best to present descriptions of these in advance of the general 

 report. 



All measurements given in the present paper are in millimeters, and, 

 so far as possible, Ridgway's Nomenclature of Colors has been used 

 as a standard. For the privilege of examining much material needed 

 for comparison in this connection the writer is indebted to the authori- 

 ties of the American Museum of Natural History, the Academy of 

 Natural Sciences of Philadelphia, the United States National Museum, 

 and the Museum of Comparative Zoology, who have generously 

 placed at his disposal the several collections respectively under 

 their care.
