232 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 93 



Similar in color to dominicus but with smaller bill. 



Seventeen males, wing 89.0-99.5 (93.5), culmen from base 18.0- 

 22.0 (19.8), tarsus 31.2-36.2 (32.9) mm. 



Seven females, wing 86.9-97.1 (90.3), culmen from base 17.7-21.5 

 (18.8), tarsus 30.0-33.0 (31.2) mm. 



South America, from Venezuela south to central Argentina. 



This form is very similar to the West Indian bird except for its 

 smaller bill. The only specimen I have seen from Argentina is 

 elightly paler than birds from farther north, but it is immature and 

 I consider its colors uncertain. It is possible that there may be two 

 forms in South America, but this can be determined only with more 

 abundant material.

On March 31, 1939, I saw a water-turkey at Laguna Larga, near

 Hueyapa on March 21, 1940, and recorded others along the river be- 

 tween Boca San Miguel and Tlacotalpam.
