search was made in June 1901, and nothing could be seen of 

 the birds. Yours &c,

Sirs, — Reviewing Mr. Chapman's paper " On new Peruvian 

 Birds " in the April number, 1902, pp. 337, 338, you made 

 a remark as follows ; — 



"The Chlorochrysa (Ch. fulgent issima) is apparently the 

 same as that described and figured in this Journal (Ibis, 

 1901, p. 716, pi. xv.) by Graf v. Berlepsch and M. Stolzmann 

 as C. hedwigce ; and, if so, Mr. Chapman's name (August 

 1901) will have priority." 



In connection with this allow me to state that there can- 

 not be the slightest doubt that Chlorochrysa fulgentissima 

 Chaprn. is the same as Ch. hedwigce Berl. & Stolzm. The 

 question of priority is perhaps still open to some doubt. It 

 is certain that the copies of the article containing the 

 description of the Chlorochrysa by Mr. Chapman (bearing 

 the impression " Author's Edition, extracted from l Bulletin 

 of the American Museum of Natural History/ vol. xiv. 

 Article xix. pp. 225-228, New York, September 7th, 1901") 

 were received here in the second part of the month of 

 September, but some of my friends are of the opinion that 

 Authors' editions extracted from a periodical and sent in 

 advance of the publication of the periodical cannot be re- 

 garded as publications in the ordinary sense, because at that 

 time they are not to be obtained through any bookseller, being 

 only accessible to a limited number of writers, to whom they 

 are sent voluntarily by the author of the article. Provided 

 this be the general rule of authors, we have only to make 

 an inquiry whether the number of the 'Bulletin of the 

 American Museum of Natural History ' containing the 

 article xix. of Mr. Chapman, bearing the date August 1901, 

 was really published in August 1901 or later, viz. earlier 

 or later than the October number of c The Ibis' of 1901. 

 Unfortunately I am not able to give any statements in tin's 

 connexion.
