46 THE AUSTRAL AVIAN RECORD [Vol. II. 



Cannabia, on p. 31, with the two species, C. 'pro'pna 

 {^=F. cannabina Linne) and flavirostris , is an absohite 

 synonym of Acanthis Borkhausen. 



On p. 49 Motacilla thunbergi is described, and this 

 name is now commonly accepted. 



In the Tables are given Phyllopseusta Meyer and 

 Rhadina B. {Phyllopseusta Mey.). This is a most inter- 

 esting introduction, which seems to have escaped 

 Richmond's observation. In the text we find, on p. 53, 

 Phyllopseusta used for hippolais Linne alone, and, p. 54, 

 Rhadina for sibilatrix Bechst., acredula L. {=trochilus L.) 

 and rufa Latham. 



Phyllopseustce was introduced by Meyer (Beschr. 

 Liv. and Esthl., p. 122, 1815) as a group-name, and has 

 been rejected (we agree correctly) as not being generically 

 or subgenericaUy proposed. For the first four species 

 of Meyer's group — ^which included "the species iS. hippolais 

 Xiinn., sybilatrix Bechst., fitis Bechst., rufa Lath., and 

 regulus Lath. — two genera are commonly accepted : 

 " Hypolais Kaup 1829, and Phylloscopus Boie 1826." 



In the Isis 1828, p. 1283, Brehm utihzed Hippolais 

 and Phyllopneuste Meyer for these two groups, but at 

 this place these are nomina nuda. 



Hypolais introduced by Kaup in 1829, is later than 

 BiUberg's Phyllopseusta, and as no author appears to 

 have anticipated BiUberg in fixing Phyllopseusta, this 

 genus -name will displace Hypolais Kaup. BiUberg's 

 Rhadina becomes, of course, a synonym of the earher 

 Phylloscopus Boie 1826. 



In connexion with this, it is interesting to note that 

 in the Gat. Gen. Subgen. Birds, p. 34, 1855, Gray used 

 Phyllopneuste as of Meyer 1822, for the " S. hippolais 

 Linne " group, and in the Handhst Gen. Spec. Birds 

 (pt. I., p. 215, 1869) he utihzed Phyllopseuste Meyer 1815, 

 for the same group. 



It would now appear necessary to revert to Phyllopseusta 

 BiUberg 1828, type (by monotypy) S. hippolais Linne 

 for this group.
