Oberholser, in the Smitltson. Miscell. Coll. vol. xlviii. p. 01, 19i)5, discussed 

 the names proposed for this genus, and accepted Euphema Wagler, and in my 

 Handlist I adopted his conclusion. Recently I have had occasion to go into 

 the matter more closely than at the time when I prepared my Handlist, and 

 I find Oberholser's decision must be reversed. 



The lirst name to be introdnced was yanodcs, by Vigors & Horsfield in 

 the Trans. Linn. Soc. Lond. vol. xv. ji. 274, who designated as type Psittacus 

 discolor Shaw. Oberholser, accepting the date of this paper as 1827, rejected 

 Xuiiodes on account of the prior Sa/iodes Schunherr, Cure. Dis]). Meth. p. 322, 

 1826. Bnt the part of the Linnean Transactions containing Xanodes was issued 

 in 1826, so that an awkward position would have resulted had it not been that 

 Schiinherr had previously published Xanodes in the Isis, p. 587, 1825 ; so that, 

 though Mr. Oberholser's dates were incorrect, Xanodes is nevertheless invalid. 



In the Traitc d'Urn. p. 205, Lesson proposed Latkamus as a substitute 

 for Xanodes (preoccupied). Oberholser rejected this name, as he contended that 

 Lathamm had been used in the Centurie Zool. p. 03. pi. 18 in conjunction with a 

 bird which was not congeneric with discolor Shaw, and that this usage appeared 

 anterior to the Traitc introduction. Oberholser used as dates those on the title 

 pages of the two publications, namely, 1831 for the Traitc, and 1830 for the 

 Cent. Zool. But the latter was obviously incorrect, as articles in the Cent. Zool. 

 bore dates ranging from 1822 to March 1831. 



Moreover in the Joarn. autour Globe du " "J'/ietis," ii. p. 313, 1837, Lesson 

 stated he had introduced new names for the divisions of Parrots in the Traitc 

 published in 1830. I therefore endeavoured to fix the dates of issue of the 

 Traitc and Cent. Zool. so that the priority of Latkamus in 'Traitc or Cent. Zool. 

 sliould be settled. As it is probable that these dates will have a bearing ujion other 

 matters as well as the one at issue I herewith give my results. 



The Bibliotheqne Fran^aise gives as dates of receipt of the jjarts of the Traitc 

 d'Om. as follows :
