1 06. Pagolla wilsonia crassirostris (Spix). 



Orthodromics wilsonius crassirostris Todd, Ann. Carnegie Mus., VII, 191 1, 

 416, in text (Buritaca; crit.). 



Additional records: Cienaga (Univ. Mich. Exp.). 



Five specimens : Buritaca and Punto Caiman. 



On the name of this form consult the present writer's remarks in 

 the above reference. Two of the above series (Nos. 43,138 and 43,196) 

 obviously belong to the southern rufous-naped form. A third speci- 

 men (43,139), shot at the same time of year (September) is excessively 

 worn and faded. The other two skins are in immature plumage, in- 

 distinguishable from specimens shot in the Isle of Pines. There is 

 nothing to show that the two forms are distinguishable at this stage, 

 and the presumption is that all of the above specimens belong to the 

 resident race. 28 



This plover appears to be rare, and was met with only on the beach 

 at Punto Caiman from September 28 to October 2, 191 3. In addition 

 Mr. Smith sent in a single specimen from Buritaca, collected Septem- 

 ber 18, 1899. 



107. Belonopterus cayennensis cayennensis Gmelin. 

 Two specimens : Fundacion. 



A single pair of this species (the only ones observed) were in the 

 drier part of the marsh at Fundacion. The specimens compare favor- 

 ably with others from the Caura River, Venezuela, assumed to be 

 typical cayennensis. It was not recorded again until the summer of 

 1920, when a single pair were noted in a marshy place along the river, 

 several miles inland from Rio Hacha. On the savannas between Va- 

 lencia and Camperucho, however, it was found to be abundant a little 

 later, in August. 



28 Since the above was written Mr. Ridgway (Bulletin U. S. National 

 Museum, No. 50, 1919, 113) has described the Wilson Plover of the northern 

 coast of South America under a new name, cinnamomina, quoting crassirostris 

 of Spix as doubtfully the same. We see no necessity for renaming the form 

 in question under the circumstances, nor can we agree with Mr. Peters 

 (Bulletin Museum of Comparative Zoology, LXI, 1917, 405) that rufinucha 

 is the proper name for the West Indian bird, even if distinct. It will be noted 

 that the name rufinucha has been repudiated by Mr. Ridgway himself.
