As stated by Mr. Clark, the Margaritan bird is somewhat more 

 highly colored and the black throat averages more extensive. The 

 differences in the bill and feet, although slight, appear to be fairly 

 constant.

It is with considerable hesitation that I have admitted the Mar- 

 garitan bird to even subspecific recognition. In the comparatively 

 large series before me, none of the supposed distinguishing characters 

 are constant. I do not find any noticeable difference in size or col- 

 oration, although a majority of the birds have the crests shorter than 

 those from the mainland.
