CHETTUSIA GREG ARIA.

found it very shy in the savannas of Kordofan and Sennaar ; it frequented sandy localities and ground that 
had been burnt; he observes that they seldom alighted on the ground, but mostly moved in quick low- 
flying flocks over the plains, sometimes crossing the caravan -roads, which gave him an opportunity of shooting 
several from horseback; otherwise it was not possible to get near them. They were, as a rule, quite silent; 
but now and then he heard it utter a shrill, short whistle. He found its food to consist of grasshoppers, 
spiders, beetles, and larvae. In Sindh this Plover seems to be a favourite quarry of the Laggar Falcon. 
Capt. Butler, writing of a pair of these Falcons and a flock of Lapwings, remarks that when the latter saw 
their enemies approaching they “ used to rise in a flock closely packed together to an immense height in the 
air, wheeling and darting in all directions. It was of no use, however, trying to escape, the two Falcons 
would follow them up until an opportunity occurred, and then one of them, with a velocity beyond 
description, would make a stoop into the midst of them and strike its victim, descending with it in its claws 
slowly to the ground.” 
Nidification . — Little is known respecting the nesting of this species. Mr. Dresser describes an egg sent 
to him by Mr. Moscliler, taken near Sarepta, as closely resembling those of the common Lapwing, but 
somewhat paler in ground-colour, and more sparingly marked with spots and blotches. 
Genus LOBIVANELLUS. 
Bill much as in the last genus, but longer ; a lappet of nude red skin proceeding from the 
anterior corner of the eye and impending the lores. Shoulder furnished with a tubercle, which 
develops at the breeding-season. Tail as in Chettusia ; legs longer and more slender. Tarsus 
nearly three times as long as the middle toe ; outer toe attached to the middle at the base ; hind 
toe and claw' very small.
