VENTRAL VIEWS OF THE HYBRIDS 
The same birds photographed in fig. 3 are here shown, turned over. The males are seen to be 
as much alike below as above, while the differences between the females are even more 
striking in this aspect. Arrangement of birds is the same as in the preceding cut, as 
follows: (a) female hybrid from cross of Reeves male and Prince of Wales female; (b) male 
hybrid from the same cross; (c) male hybrid from cross of male Prince of Wales and female 
Reeves; (d) female hybrid from the latter cross. (Fig. 4.)
