At the Meeting of the British Association of 1850, Gould gave an account of 
Macgilhvray’s results as transmitted to liim, and therem is the extract from 
Macgilhvray’s letter : “ You mil obhge me hy comparing the Chlamydm 
from Cape York with the other members of the genus, as I have a strong 
suspicion that it may be different. I shot it wliile playing about a bower. 
I have sent it to the British Museum.” Gould reported: “ I have complied 
with IVIr. Macgilhvray’s wish, and find the bird to be quite distmet, both from 
C. nuchalis and C. 7 naculata, and have accordingly named it cerviniveniris, 
from the colouring of the abdomen.” The description was then attached, 
w^liich Gould had read before the Zoological Society some time before. 
Tliis report was pubhshed by Jardine hi his Contributions to Ornithology 
for 1850, and the Proceedings of the Zoological Society for 1850 were not published 
until w'oll into 1851. 
Macgilhvray’s full notes were pubhshed m the Narrative of the Voyage of 
H.M.S. “ Rattlesnake ” and quoted by Gould as foUows : “Two days before we 
left Cape York, I w^as told that some Bower-Birds had been seen hi a thicket
