only one example of Cross (2) ) are similar. The Ducks are 

 unknown. 



Drakes in full plumage resemble those of the first genera- 

 tion (p. 241) throughout, except for the head. The vent is 

 perhaps a little darker, but that is not a constant character ; 

 the flank feathers also in some individuals show much more 

 red, and more rarely a trace of a subterminal spot, and some 

 feathers are indistinguishable from those on the flank of a 

 Wigeon (Cf. PL xii., figs. 9 and 10). The head is a uniform 

 dark brown, almost black ; it shows a green metallic gloss 

 only in a broad stripe behind the eye, meeting its fellow of the 

 023posite side on the nape ; the feathers on the top of the head 

 from the base of the culmen to the junction of the metallic 

 stripes have light brown edgings, this portion of the head 

 resembling that of the pure Pintail. The metallic bands are 

 precisely similar in iDOsition to the metallic portion on a Teal's 

 head, but slightly duller in colour, while the dull dark colour 

 over the rest of the head is most nearly matched by a 

 Shovelers head when coming out of eclipse. The bill, unlike 

 that of the first generation, is purely Spotbill. 



Eclipse plumage. Similar to that of first generation.

Only one brood of this cross (3 $ 1 ? ) has been reared. The 

 Drakes are, perhaps, the most remarkable birds that have been 

 bred during these experiments. The general appearance in full 

 plumage isthat of the first generation (light variety) $ in eclipse. 

 The back is a mixture of the back of the $ (light variety)^ 

 in eclipse, while some feathers are like those of the light ? , 

 both these feathers, be it noted, resembling in pattern those 

 of no known pure species. 



The head is precisely as in the light <$ in eclipse, except that 

 the sides of the face and cheeks are white. The underparts 

 are pure white, but the sides of the chest are chestnut, with black 

 subterminal spots. The flank feathers are very duck-like, being
