14 ERNEST WAUREN. 



galerita; the difference is more obvious when the bill is 

 wetted. The upper mandible, from forehead to tip, measured 

 1'7 inches (43 mm.); depth from forehead to lower inner angle 

 0'93 inch (24 mm.). The lower edge of upper mandible, when 

 bill was in a normal position of rest, sloped upwards towards 

 the inner corner at an angle of about 19° to the horizontal. 

 The hook was larger than in the male-bird and was more or 

 less intermediate in shape between that of the male and 

 female. The upper edge of the lower mandible was, on the 

 whole, somewhat more concave than in the male-, but less so 

 than in the female-bird. 



Cere partially feathered so that the nostrils, which were 

 situated just inside the junction of the bill and head, had the 

 back edge feathered and the front edge naked, a condition 

 strikingly intermediate between that seen in the male- and in 

 the female-bird. 



The three months old hybrid (PI. II, D) was not sufficiently 

 mature to render it advisable to compare its measurements 

 with those of the parents. In all general characters it very 

 closely resembled the mature hybrid. 



The orange crest was already rather longer than in the 

 older hybrid, but none of the feathers were recurved. 



The area of the lores coloured yellowish-orange Avas rela- 

 tively less than in the three years old hybrid, and considerably 

 smaller than the red area in L. nasica. Naked skin around 

 the eye very pale bluish-white. Iris very dark brown. 



Bill very dark, but not quite so black as in C. galerita. 



The shape of the upper mandible and hook of same Avas 

 somewhat nearer to that seen in the male than Avas the case 

 in the older hybrid. Also, the curvature of the upper edge of 

 the loAver mandible was somewhat closer to that of the male. 



From a Mendelian point of view animal hybrids derived 

 from the crossing of species are as a rule singularly unsatis- 

 factory. They usually exhibit an intimate blending in the 

 majority of the characters of the two parent species, and
