BIRDS CUCULIDAE — CROTOPIIAGA RUGIROSTRIS. 71 



Family CUCULIDAE. The Cuckoos. 



Bill compressed, gently curved, eomotimes attenuated, and generally lengthened. A ftw bristles at the haim of the bill or 

 none. Tarsi longtbonod ; toes rather short. Tail long and soft, of 8 to 12 feathers. 



The preceding diagnosis covers a great variety of forms, although those found within tin- 

 United States embrace but three genera, which may be indicated as ioHows, each forming the 

 type of a sub- family : 



A. Tail feathers eight ; face naked. 



Crotopiiaga. — Bill shorter than the head. Very high, and much compressed. 



B. Tail feathers ten ; face covered with feathers. 



Gkococcyx. — Bill longer than the head. Loral feathers stiff, bristly. Tarsi much longer 



than the toes. Live on the ground. 

 CoccTGUS. — Bill not as long as the head. Loral feathers soft. Tarsi shorter than the 



toes. Live on trees. 



CROTOPIIAGA, LinnjEus. 



Crotophaga, Linn.eus, Systema Naturie, 1756. 



Bill as long as the head, very much compressed; the culinen elevated into a liigh crest, extending above the level of the 

 forehead. Nostrils cxposrd, elongated- Point of bill niiu-h decurved. Wings lengthened, extending beyond the base of the 

 tail, the fourth or fifth quill longest. Tail lengthened, of eight graduated feathers. Toes long, with well developed claws. 



The feathers in this genus are entirely black ; those on the head and neck with a peculiar 

 stiffened, metallic or scale-like border. The species are not numerous^ and are entirely confined 

 to America. 



For a number of years the occurrence of specimens of Crotophaga at variotis points on our 

 sea border has been recorded, but the genus has never been formally introduced into our fauna. 

 There is, however, no reason to doubt its existence as a regular summer visitor on the keys 

 and shores of Florida, as well as at various points on the Gulf of Mexico. In the following 

 pages I describe two species, and it is quite possible that others may occasionally occur within 

 our limits.
