Fig. 110.—JLatJiria cinerea. The members of this genus are birds of rather large size with proportionately small feet. The bill, which is keeled and sharply hooked at the tip of the upper mandible, is wide and depressed at the base, where the width is about two-thirds the length of the exposed culmen. The rictal bristles are moderately developed. The wing is rounded, the third, fourth, and fifth primaries longest and equal, the second about equal in length to the sixth, and the first about equal to the seventh. The tail is almost square at the tip and about ten-twelfths the length of the wing. The tarsus is about equal to the middle toe and claw in length.
