2O PARABOLIC PIGEON. 



THIS species is one of the discoveries of the 

 celebrated naturalist and traveller Le Vaillant, 

 whose splendid work on the African birds is wor- 

 thy the industry of such an assiduous and enter- 

 prising individual. It measures about fifteen inches 

 in length from the tip of the beak to the extremity 

 of the tail : its prevailing colours are a rich pur-

 front, the top of the back, and the whole of the 

 under parts, that on the upper part of the back 

 and the breast being brightest: the feathers on 

 the latter being blackish in the centre, gives it 

 the appearance of being spotted : the top of the 

 head and the occiput are of a grey -blue : the lesser 

 and middle wing-coverts are adorned with a few 

 whitish spots of a round shape ; the other coverts 

 are the same, with triangular spots : the tarsi are 

 covered with feathers in part, the rest is naked 

 and of a clear yellow : the feet and claws are also 

 yellow : the beak is of a very deep yellow, and the 

 membrane at the base of the beak is orange : the 

 irides are brown orange.

 male and female are always found in pairs ; but

 construct their nests like the Stock Dove, and 

 produce ten white eggs: this species has a very 

 remarkable flight, not going in a straight line, 

 but upon commencing its route, it describes a para- 

 bola, and continues forming a series of arcs during
