who unite these two forms, this statement may appear to be 

 a rather bold one. But it is not wrong to say that those 

 who cannot distinguish between C. pertinax and C. cerugi- 

 nosus are not well acquainted with these birds. I myself did 

 not know them when, two years ago, in my ' Katalog Vogels. 

 Mus. Senckenberg.' (p. 156), I ventured to unite the two 

 species, having been (like Finsch, Schlegel, and others) 

 misled by young specimens of C. pertinax and by inexact 

 localities, so that the distribution could not be studied. 



With more material at hand it might not be wrong to 

 regard this new form as a subspecies of C. aeruginosas, as it 

 is close to it, and specimens might easily be found that very 

 nearly approach it, but I prefer to keep it as a species, all the 

 more on account of its isolated habitat. 



C. arubensis is very common everywhere on Aruba. The 

 first morning when out shooting with my friend Dr. Cole, I 

 obtained a specimen of it. Thinking that it was the common 

 continental form, I was content to pick up a specimen occa- 

 sionally, and brought home four skins only. My much 

 honoured friend, Count Tommaso Salvadori, first called my 

 attention to the light-coloured foreheads and cheeks in my 

 skins as soon as he saw them, and I was glad that I found 

 the surmises of this great ornithologist well founded. 



C. arubensis is similar in its habits and screaming voice to 

 C. pertinax, and also lays its eggs in holes dug out in 

 old ants' nests and trees, and in the natural caves and 

 holes in the lime rocks. Its food consists mostly of the 

 fruits of Cereus, Melocactus, and other plants.
