end of the dry season, he encountered a flock of about 30 below La 

 Jagua, near the mouth of the Rio Chico, and shot two or three that 

 he was unable to retrieve as they fell on mud banks that were not 

 passable. In March 1921, M. J. Kelly, of the Everhart Museum at 

 Scranton, Pa., secured two on a savanna area near Chepo. These, 

 mounted for exhibition for a time, subsequently came in an ex- 

 change to the U. S. National Museum. 



On August 27, 1934, Wedel shot a female at Puerto Obaldia, 

 San Bias, which was purchased for the Brandt collection, now in 

 the museum at the University of Cincinnati (Brandt, Auk. 1938, p. 

 288). 



The specific name chilensis is from Parra chilensis Molina of 1782, 

 a name that some have refused, since the description includes a 

 reference to a frontal shield like that of a jagana. The formal 

 diagnosis describes the short toes and crested head of the plover, 

 and the extended account of habits also is of that species. Many 

 early descriptions are in part composite but are accepted from the 

 action of a reviser who decides the proper allocation of the name. In 

 the present instance the question has been discussed in detail by me 

 (U. S. Nat. Mus. Bull. 133, 1926, pp. 168-169) and by Peters (Bull. 

 Mus. Comp. Zool., vol. 65, 1923, pp. 295-296). In both references 

 chilensis is designated as the name to be accepted for the Belonopterus.
