A single specimen in juvenal plumage taken at San Antonio, January 12, 

 indicates, in connection with Hellmayr's record from the Rio Sipi, that this 

 species ranges from sea-level to at least 6600 feet. 



Three adults from Barbacoas are somewhat darker, and less rufescent 

 than the type and two other specimens from Panama. Possibly the dif- 

 ference may be due to the greater age of the Panama skins.

 Santa Marta); Ihid., 1908, p. 158 (San Antonio). 



Neocrex uniformis Hart., Nov. Zool., 1901, p. 369 (Pambilar, S. Javier, Ec). 



Bangs finds on comparison no difference between a specimen from San 

 Antonio and the type of this species, and hence concludes that uniformis 

 Hart, is a synonym. I therefore refer our three specimens from Barbacoas 

 to this species.

Abundant in the Cauca .Valley, where we took specimens in December, 

 May and August. Lacking typical specimens of G. c. galeata for compari- 

 son, I accept Mr. Bangs' proposed form from the Cauca Valley, which is 

 said to differ from galeata only in smaller size. I agree with Bangs, Hartert 

 and Rothschild (Bangs, I. c.) that the relationships of Old and New World 

 Gallinules are best expressed by treating them as subspecifically related.

 p. 169 (Savanna at Bogotd, Col.). 



Char, subsp. — Similar to P. m. melanops but axillars not barred, the upperparts 

 darker, the interscapulars in the adult largely chestnut, like the wing-coverts. 



This rail-like Gallinule is common on the reed-grown sloughs of the 

 Bogota Savanna. It is the most northern representative of a species which 

 inhabits the Temperate Zone at sea-level in Argentina and Chile.
