the outer webs white, spotted ; under-coverts bluish- white. 

 Tarsi one inch long, thinly clothed with feathers of the same 

 colour as the belly and vent. Toes scarcely pectinated, 

 having instead small close hard scales. Tail consisting 

 of 18 feathers, pointed, the four centre ones the longest. 

 Length 19 inches. Breadth 12 inches. Weight one and 

 a half to two pounds. . 

 Female smaller, darker on the hind part of the neck ; colour less 

 distinctly marked, and the tail scarcely half so long as the 

 male bird. The trachea and gizzard of the present spe- 

 cies, as regards muscular consistence and size, differs but 

 little from the preceding. 



Their flight is swift and steady, with little noise. Their habits 

 approach so closely to those of the former, that to describe them 

 would be only repeating what has been stated of that species. 

 Suffice it to say, they inhabit the same range of country, form 

 their nests after the same fashion and in similar places, subsist 

 on the same sort of food, having young at the same season. 

 Eggs 11 — 1 5, light ash-colour, about the size of a pigeon's. The 

 voice is Chick, chick, chick, the sounds running into each other. 

 They are more numerous than the former, with whom they asso- 

 ciate, and seem to live in harmony ; they are shy, and difficult 

 to be approached . The flesh is similar to that of the former.
