104 Mr. E. Hartert on the 



2. The bend of the wing in C. canifrons is described as " clear 

 yellow, marked with scarlet next the body," while of that of 

 C. ochroptera I say " yellow, with a few scanty red feathers 

 sometimes to be seen next the body/' I think the difference 

 between these two descriptions is not very great, and that 

 they might well apply to the same species. I said of my 

 three specimens from Aruba (for I only described these in 

 my article) " with a few scanty red feathers sometimes to be 

 seen next the body,'" but 1 have a specimen alive now, and I 

 have seen others, which have more red there, although never 

 nearly so much as in C. rothschildi. I am sure Mr. Lawrence 

 would not have described the bend of the wing of his bird as 

 " yellow, marked with red next the body/^ if the whole of 

 the cubital erlge and the shoulder-patch had been bright 

 scarlet mixed with some yellow, as is the case in C. roth- 

 schildi. 



3. Mr. Lawrence says, '' The primaries in C canifrons are 

 blue, tliose of C. ochroptera black .^^ I regret to be obliged 

 to say that this statement is incorrect. The primaries in 

 C. ochroptera are — in spite of statements to the contrary — 

 deep blue, just like those of C. rothschildi and the supposed 

 C. canifrons. Mr. Lawrence says I did not mention the 

 colour of the primaries ; but they are black in my figure of 

 C. ochroptera in ' The Ibis,^ and Salvadori states them to be 

 black in the ' Catalogue of Birds.' I did not mention their 

 colour because I described only those parts of my wild-shot 

 Aruban birds which I thought ought to be noticed, since 

 most, if not all, previous descriptions seemed to have been 

 derived from caged birds. As to my figure in ' The Ibis,' the 

 primaries of both species were blue in Keulemans's coloured 

 pattern, and they are blue in all my separate copies, and in 

 a number of other copies which I have seen. Mr. Lawrence 

 must either unluckily have got a wrongly coloured copy 

 (which is not probable) or must have looked at the figure by 

 artificial light, when the primaries do look rather black. 



4. " The thighs of C. canifrons are grey, in C. ochroptera 

 they are yellow." I have stated (Ibis, 1893, p. 302) that in 

 young as well as in caged birds the yellow colour is more
