Diatropornis, from dt.drpur.oQ, difFereus, and o/)>j?, avis; the type 

 and only species being Tapinopus ellloti Milne-Edwards. This will 

 now stand as 



Diatro'pornk ellioti (Milne-Edwards). 



PERISTEBA Swainson. 



The Colnmbine genus Peristera Swainson^ is untenable because 

 of Peristera Rafinesque'^ in Mollusca; and may be called Claravis, 

 from clara (clarus) and avis, the type being Coliimba einerea 

 Temminck. The name of this species, however, should be pretiosa 

 Ferrari- Perez;' for Columba einerea Temminck and Knip"* is pre- 

 occupied by Columba einerea Scopoli.* 



The species will then stand as follows : 



Glarav'is pretiosa (Ferrari -Perez). 



Claravis geoffroyi (Temminck and Knip). 



Claravis mondetoura (Bonaparte). 



HARPE Bonaparte. 



Harpe Bonaparte" is preoccupied in ichthyology by Harpe Lace- 

 pede.' Harpa Sharpe,* for the same group, is also untenable on 

 account of Harpa Lamarck,' a genus of Mollusca. As no other 

 name is available, there may be proposed Nesierax, from •^f,ff(><;, 

 insula, and iipaS, accipiter, with Falco novie-zealandiie Ginelin as 

 type. 



The species are 



Nesierax novce-zealandice (Gmelin). 



Nesierax aastralis (Hombron and Jacquinot). 



PACHYNUS Reichenow. 

 Not only is Pachynm Reichenow" preoccupied in Hemiptera by 

 Pachynus Slal, 1866, and thus untenable under any circumstances, 

 but it is not the earliest available name for the genus. Graydi-
