350 CHARADRIIDZ., 
This pretty little Plover is said to have been obtained in Honduras by Leyland, 
part of whose collection passed into the Derby Museum at Liverpool. In the Catalogue 
of Charadriide in that Museum, by Dr. H. O. Forbes and Mr. Herbert Robinson, we 
are informed that Leyland’s localities are not always to be trusted, as occasionally 
specimens from other countries were mixed up with the collections he brought from 
Honduras. No examples of H. cayanus from the latter place are in the Liverpool 
Museum, but, since Mr. Moore gave the “ Aloor River” as the place where Leyland 
obtained the species, we do not feel justified in rejecting the evidence entirely, though 
the bird has not been met with by any subsequent collector. 
H. cayanus appears to have the habits of a Sand-Plover and to be found on the 
inland rivers throughout the wide area it inhabits in South America. 
Subfam. CHARADRITNA. 
The true Plovers and Lapwings differ from the members of the foregoing subfamily 
in having the tarsus reticulated both before and behind, or covered with small hexagonal 
scales. The range of these birds is world-wide, and the majority of Plovers are included 
in the Charadriine, a great number being resident within the tropics. On the other 
hand, some species, like the Grey and the Golden Plovers, nest in the extreme north of 
both hemispheres, and migrate in winter to the most southern lands. 
SQUATAROLA.

Mus. xxiv. p. 182 (1896). 
The Grey Plover, the sole representative of the genus Squatarola, is closely allied to 
the Golden Plovers (Charadrius), and in the young plumage is actually spangled with 
golden-yellow like the latter. It is to be recognized, however, by the presence of the 
hind toe. The members of both genera assume a beautiful and distinct breeding- 
plumage in the summer, when the underparts become black.
