dascalus Bonaparte^ has nearly thirty years' priority, and there 



seems to be no valid reason for its rejection. 



The type and only species should therefore stand as 

 Graydidascalus brachyurtis (Temminck and Kuhl). 



HEMILOPHUS Swainson. 



The name Hemilophm Swainson" is preoccupied in Coleoptera by 

 Hemilophus Serville.^ The next name seems to be Mulleripicus 

 Bonaparte,'' type Pkm jmlveridenhis Temminck. 



The only recognized species is 



Mulleripicus jmlveyulentus (Temminck). 



DENDROBATES Swainson. 



Dr. C. AV. Richmond has already pointed out' that Dendvohates 

 Swainson* is untenable by reason of a batrachian genu?, Dendro- 

 bates Wagler,' but proposed that Eleopkm Bonaparte' ])e used in 

 its place. The proper name, liowever, would appear to be Ven- 

 iliornis Bonaparte, since in the list of genera (l. c.) this is num- 

 bered 21, while under it are ranged as subgenera Venilia and 

 Eleojncus, all the species contained in both being now included in 

 the genus Dendrobates. This name Veniliornis has been geuerally 

 ignored, but there seems to be no doubt of the propriety of accept- 

 ing it for the group in question, rather than either of its subgenera 

 — one of the two alternatives being necessary. No type is indi- 

 cated, neither is there a subgenus Venilioniis ; Init the first species 

 mentioned, Picus sanguineus Lichtenstein, may he taken as the 

 typical one. 



With i-egard to specific names in this group, there are two of 

 those accepted in the eighteenth volume of the British Museum 

 Catalogue of Birds that require to be changed ; Avhile some doubt 

 attaches to a third. The correct name of the bird known as peru- 



vianus Taczanowski is Callonotus major Berlepsch and Taczan.,*
