The true D. iris occurs further to the eastward in Peru, 

 and Mr. Baron obtained specimens of it at Leimebamba.

Mr. Ernst Hartert stated that the names of the two 

 Nucifragce had been reversed in the note published in the last 

 number of the ' Bulletin/ and that to avoid further mis- 

 understanding he wished his full statement to be inserted 

 verbatim : — 



" Long ago C. L. Brehm had separated the Nucifraga 

 caryocatactes of Linnseus into two forms, which he called 

 N. brachyrhynchus and N. macrorhynchus, his N. brachy- 

 rhynchus, however, being the typical A', caryocatactes of 

 Linnaeus. British ornithologists generally, almost with the 

 sole exception of Seebohm, who had acknowledged the two 

 forms, had never believed in them. Prof. Newton, for ex- 

 ample (Diet. B. p. 647), had declared that, 'as in the case of 

 the Hula, this was now supposed to depend on the sex,^ a 

 statement which was certainly not right. Dr. Sharpe (Brit. 

 B. i. p. 17) had said he had ' never been able to appreciate 

 the supposed differences.' Mr. Hartert had frequently met 

 with the thick-billed form in North-cast Prussia, where he 

 had found its nests and eggs, and had collected a large series 

 of birds, and they were all thick-billed. This was N. caryoca.
