Ee-examination of the Parkinson drawing No. 27 sliows the pencil- 
drawing to be unmistakeably that of a form of Th, chrysostoma, made from the 
specimen procured on “ Feb. 3rd, 1769, Lat. 57° 30'.” On the back of the 
drawing in Parkinson’s handwriting is, “ The beak black excepting the back of 
the upper mandible and part of the under one, which is a dirty greenish 
white.”
