Thus we see that the length of the wing in males 

 varies from 71 to 7'7 inches, and in females from 8'3 to 

 8*8 inches. 



In A. castanilius the males have the wing 6'0 to 6'1 

 inches, and the adult females 71 to 7* 3. 



The young of the two species, in their mainly black 

 plumage with white under surface spotted with black, are 

 very much alike, and again as they approach maturity, when 

 the vinous breast shews many cross-bars. The females of 

 A. tousseneli approach in colour those of A. macroscelides, 

 which I consider to be a form of A. tachiro and distinct 

 from A. castanilius (cf. Reichenow, Vog. Afrikas, i. p. 554) . 



In the immature birds size alone seems to be the criterion 

 for separating A. castanilius from A. tousseneli.

This specimen still retains a few indications of immaturity, 

 but agrees very well with the plate given by Dr. Reichenow 

 (/. c).
