attention to color combinations the importance of which as a character 

 has been several times emphasized by the reviewer. 



In his remarks on the ptilosis of Podargus and the Trochilidce we notice 

 no reference to the papers of Dr. Hubert Lyman Clark in ' The Auk,' 1901, 

 p. 167 and 1906, p. 68. Mr. Miller will find some of his statements al- 

 ready recorded there. While it is satisfactory to have previous work 

 verified, reference should be given to it, and we think these two papers 

 must have escaped Mr. Miller's eye. 



In a footnote on p. 134 occur some comments on generic names of 

 Parrots. Among other things Mr. Miller fails to see how the names pro- 

 posed by Kuhl for " sections " of certain genera can be rejected as has been 

 advocated by Mr. Gregory Mathews (Novitates Zool, XVIII, p. 11). 

 We heartily agree with Mr. Miller that no distinction can be made between 

 subgenera and " sections " and that these names must be recognized. In 

 the case of Conurus, however, Mr. Miller apparently overlooked the fact 

 that, as Mr. Mathews explains. Lesson fixed as the type of this genus a 

 species of Palceornis, which action transfers the name Conurus to this old 

 world group necessitating the adoption of Aratinga for the South American 

 Conures. — W. S.
