Dacelo cervina, Gould in Proc. of Zool. Soc. Part V. 1837. Tue bird figured in the accompanying plate differs from every other known species of true Dacelo in the delicate buff or light fawn yellow which is spread over the whole of the under surface; and as this colour extends to the base of the feathers, I am led to believe constitutes a permanent character; I have therefore given it the specific appellation of cervina. It is a species of great rarity ; two specimens only have come under my notice, one of which is in my own collection, and the other in that of the British Museum. I am unable to record any account whatever of the history of this fine bird, further than that I have reason to believe it is an inhabitant of the eastern and northern portions of New Holland. When compared with the other members of the genus it may be considered a diminutive species, while at the same time it is not surpassed by any in the brilliancy of its colours, particularly in the lazuline blue, which is spread over the back and wings.
