Nos. 2 & 3.] THE AUSTHAL AVIAN RECORD 61 



In investigating the preceding, I noted the following 

 preoccupied names, and as I consider the genera vahd, 

 herewith propose substitutes — 



Platygnathus Hartlaub, in Wiegman's Arch, fiir Nat. 

 1852, p. 132, is untenable on account of its prior usage 

 by Dejean (Catal. Col., 2nd ed., 1834), Laporte (in BruUe 

 H.N., Anim. artic, Vol. II., p. 404, 1840), and Agassiz 

 (Poiss. F.V.G.R., p. 60, 1844). 



I would substitute — 



SuBMYiAGRA, with P. vanicorensis Quoy et Gaimard, 

 Voy. " FAstroL," 1830, as type. 



Microlestes Meyer, Zeitschr. ges. Ornith., Vol. I., p. 197, 

 1884, cannot be used on account of the prior introduction 

 of the name by Schmidt-Goebel (Heifer's Samml., Vol. I., 

 p. 41, 1846), Pleininger (in Wurtt. Jahr. Ber. 1847), and 

 Brown (Index Pal., p. 725, 1848). 



I therefore introduce Arfakornis with Microlestes 

 arjakiamis Meyer as type. 



It is well known that the code of the American 

 Ornithologists' Union differs from the International 

 Code, in that the latter would compel the usage of " one 

 letterism " in differentiating valid generic names, whereas 

 the former does not. With that quaint but well-known 

 American idea of progressivism, the American Ornitho- 

 logists' Union have subscribed to the International 

 Commission's Opinions while not observing the Code. 

 It would now appear they do not wish to accept that 

 Code, but hope to amend it to agree with their own : 

 during the interval they still adhere to their own Rules. 

 It is now quite speculative as to the result, but the 

 trend is in favour of the Americans. I profess to follow 

 the International Code in its entirety and am accepting 

 the Opinions as now rendered : these all suggest that 

 " one letterism " will be abolished.
