Family CHARADRIIDAE: Plovers 
BELONOPTERUS CHILENSIS CAYENNENSIS (Gmelin): Cayenne Lapwing 
Parra cayennensis GMELIN, Systema naturae, vol. 1, pt. 2, 1789, p. 706 (Cayenne). 
SPECIMEN COLLECTED 
lad. 9, Venezuela, Puerto Ayacucho, Rfo Orinoco, January 4, 1930. 
The specimen is in molting condition. It fully agrees with the 
characters of this race as given by Brodkorb (Occ. Pap. Mus. Zool. 
Univ. Michigan, No. 293, 1934, pp. 2-4). 
The race occurs from Colombia (west to the Atrato and Cauca 
Valleys) and east through Venezuela and the Guianas to northern 
Brazil, where it intergrades with lampronotus along the Amazon. 
HOPLOXYPTERUS CAYANUS (Latham): Spur-winged Plover 
Charadrius cayanus LATHAM, Index ornithologicus, vol. 2, 1790, p. 749 (Cayenne). 
SPECIMENS COLLECTED 
lad. o&, Venezuela, Buenos Aires, Brazo Casiquiare, February 21, 1931. 
lim. 9, Venezuela, Puerto Ayacucho, Rfo Orinoco, January 4, 1930. 
The female marked immature resembles the adult male in plumage 
and even has the well-developed carpal spur, but it has the black 
pectoral band much broader than the male. 
PLUVIALIS DOMINICA DOMINICA (P. L. S. Miiller): American Golden Plover 
Charadrius dominicus P. L. 8S. Mitiuer, Natursystem, Suppl., 1776, p. 116 (His- 
paniola). 
SPECIMEN COLLECTED 
1 ad. c, Brazil, Santa Isabel, Rio Negro, October 13, 1930. 
A migrant from North America, going as far south as the Argentine 
pampa country. 
CHARADRIUS COLLARIS Vieillot: Collared Plover 
Charadrius collaris Vir1uLoT, Nouv. Dict. Hist. Nat., vol. 27, 1818, p. 136 (Para- 
guay, ex Azara). 
SPECIMEN COLLECTED 
lim. 9, Venezuela, Buenos Aires, Brazo Casiquiare, February 21, 1931. 
The single example obtained is in molting condition; all the remiges 
are new and only partly grown. On an island just below San Carlos, 
Rio Negro, Venezuela, on January 27, 1931, Holt found and photo- 
graphed a chick of this species. 
The supposedly smaller northern race C. c. gracilis Cabanis appears 
to be unrecognizable. It has been supported, however, fairly recently 
by Laubmann (Végel Paraguay, vol. 1, 1939, p. 89) but more recently 
it has been “sunk” by Gyldenstolpe (Kungl-Svenska Vet.-Akad. 
Handl., vol. 22, No. 3, 1945, pp. 42-48).
