CouAS, Vaill. 



Only differ from the Cuckoos in their elevated tarsi.(l) They 

 build in hollow trees, and do not lay their eggs in strange nests; a 

 fact, so far as regards those species whose mode of breeding is 

 known, that cannot be denied. 



We may separate from them an American species with a long 

 beak, that is only curved near the tip.(2) 



M. Le Vaillant has already, and very properly, separated from the 

 other Cuckoos the 



Centropus, Illig. 



Or the CoucaIs,(3) species of Africa and India, in which the thumb 

 nail is long, straight and pointed, as in the Larks. Those which are 

 known belong to the eastern continent. They also build in hollow 

 trees.(4) 



We should also distinguish with that naturalist, the 



CouROLS,(5) or VouROUDRious of Madagascar, 



In whose thick, pointed, straight and compressed beak, which is 

 but slightly arcuated at the point of its upper mandible, the nostrils 

 are pierced obliquely in the middle of each side. Their tail is com- 

 posed of twelve quills. They live in the woods, and build like the 

 preceding birds. They are said to be mostly frugivorous.(6) 



52; mindanensis, Enl. 277;gaira, Vieill. Gal. 44; Freycin. Voy. Zool. 26. Why 

 Vieillot makes an Anis of it, it is impossible to say. 



(1) From this division Vieillot makes his genus Cocctzus, Gal. 41. It Is the 

 Macropus of Spix, Cue. madagascariemis, Enl. 825; C Lalandii, T. Col. 440; 

 cristatus, Enl. 589; Vaill. 217;C3emkus, 295, 2; Vaill. 218; naevius, Enl. 812; 

 cayanus, Enl. 211; C. brachypterus, T. or Macropus caixana, Spix, 43; C. sent- 

 cuius, Enl. 813; Macropus phasianellus, Spix, 42. 



(2) Cue. vetula, Enl. 772. It is upon this distinction that Vieill. has founded his 

 genus Saurotheha, Galer. 38. 



(3) Coucal, compounded of Cuckoo and Lark (Coc. and Alouette); centropus, feet 

 with spurs. Vieill. has changed it into Corydonie, and Leach into Podophilus. 



(4) Cuculus segyptius and senegaknsis, Enl. 332; Vaill. Afr. 219; philippensis, 

 Nob. Enl. 824, or C. hubutus, Horsf. Jav. ; m^o-rw/jw, Nob. Vaill. Afr. 220; tolu, 

 Enl. 295; Vaill. 219; bengalensis, Urown, HI. XIII; rw>jws, Nob., Vaill. 221; 

 sethiops, Nob. Vaill. 222; gigas, Nob. Vaill. 223; atralbus, Voy. de la Coq. 

 Zool. 34. 



(5) Courol, from Cuckoo and Roller. From this division Vieill- has made his genus 

 Leptosomtjs, Gal. 29. 



(6) Cuculus afer, Enl. 387, the male, whose beak is badly drawn, and 588, the 

 female, where it is better, Vaill. 226, 227.
