HOPLOXYPTERUS. 349 
Subfam. LOBIVANELLINE. 
All the members of this subfamily have a swollen tip to their bill, as in the true 
Plovers, and in this respect they differ at once from the Oyster-catchers and Turnstones. 
The pattern of the scaling on the tarsus is also another well-marked characteristic, the 
scales being transverse on the front and reticulate on the hinder aspect. | 
Most of the species are armed with a spur on the wing and have ‘generally some 
facial wattles. The majority of them belong to the Old World, and but three genera, 
Oreophilus, Ptiloscelis, and Hoploxypterus, are found in the Western Hemisphere, the 
last-mentioned alone claiming consideration in the present work.

Hoploxypterus, Bp. C. R. xliii. p. 418 (1856) ; Sharpe, Cat. Birds Brit. Mus. xxiv. p. 135 (1896). 
The single representative of this genus of Spur-winged Plovers has generally been 
placed in the genus Hoplopterus, which embraces three well-known species of the Old 
World. The American H. cayanus, according to Dr. Bowdler Sharpe’s latest arrange- 
ment, should be placed in the Lobivanelline, whereas Hoplopterus belongs to the true 
Plovers, Charadriine. 
In addition to the transverse scaling of the front of the tarsus, which is very long, 
being nearly double the length of the middle toe and claw, the hind toe is absent, 
there is no facial wattle or lappet, and only a small spur on the wing. 
One species only is known, H. cayanus, which is found in Guiana and Brazil and is 
believed to have been met with in Honduras.
