Mr. J. Blackwall on Spiders from Upper Canada. 429 Tlie specimen just described is " the beautiful new Goat-sucker " of which Mr. Sharpe says he is not aware that I had published anj description*. I can, however, assure him that the description of this fine bird was written more than twelve months ago ; but I think it right to make him aware that I have deferred its publication until the present opportunity. My young friend Mr. Sharpe seems equally anxious to be made acquainted with the fact whether I had published on another Madagascar bird, of which he says, I " was inclined to consider it undescribed" — an opinion which Mr. Sharpe him-self once entertained ; but he afterwards kindly informed me that it might be Cossypha imerina of Dr. Hartlaub, though he at the same time pointed out some differences that existed be-tween it and Dr. Hartlaub's description. These differences he still refers to in his paper, and also further states that he " cannot guarantee the absolute correctness of his identifica-tion." From these remarks I am led to infer that it may yet be an unnamed species, as we both formerly considered it ; and, should our conjecture hereafter prove to be right, then I would venture to propose that it should be designated as Cossypha Sharper ^ G. R. Gr. Cossypha imerina, Sharpe nee Hartl. in Proc. Zool, Soc. 1871, p. 316, where copious descriptions are given of several phases that the bird in question undergoes : these, therefore, need not be repeated here. The chief reason for referring to this trivial matter is to satisfy Mr. Sharpe that I had not hitherto published or even written in reference to this bird.
