SCANSORIiE. 343 



like that of the Ululse. Their nostrils, also, are simply pierced 

 in the horn of the beak, the edges of the mandibles are 

 dentated, and the sternum (at least that of the Toiiraco) has not 

 those large emarginations, so common in the Gallinacese, 

 There are two genera of these birds : the first is, 



CORYTHAIX, Illig.(l) 



Or the Touracos, in which the beak does not mount on the fore- 

 head, and the head is furnished Vr-ith an erectile tuft. The most 

 common species, 



Cuculus persa, L.; Enl. 601; Vaill., Prom., Sec, 16 and 17, is 

 found in the vicinity of the cape of Good Hope. It is a beauti- 

 ful green, with part of the quills of the wings crimson. It 

 builds in hollow trees, and feeds on fruit.(2) The second is the 



MusopHAGA, Isert. 



Or the Plantain-eaters, so called, because their principal food is the 

 fruit of the banana. They are characterised by the base of the beak 

 forming a disk, which partly covers the forehead. The species 

 known is 



M. violacea, Vieill. Galer. 47; Totiraco violet, Vaill., Pro- 



mer., &c., pi. 18. Circumference of the eyes naked and red; 



violet-coloured plumage; occiput and primary quills of the 



wings, crimson; a white line passes below the naked space round 



the eye. Inhabits Guinea and Senegal. 



ORDER IV. 



GALLlNACEiE. Gallin.'e, Lin. 



These birds are so called from their affinity with the Domestic 

 Cock, and like it, generally have the upper mandible arched, the 



(1) Vieillothas chang-ed this name into Op^thus. 



(2) Add the Touraco-g^ant, Vaill., Prom, and Guep., pi. 19; the Touraco Pau- 

 line, Temm., Col. 23, or Opsethus erythrolophus, Vieill. Galer. 49; the Touraco 

 hrun {Phasianus africanus, Lath.) Vaill., 20, or Musophage vari^, Vieill. Galer. 48.
