wbicli apparently belong to a second sj^ecies, hitLerto overlooked, wliicli will 

 turn out to be Acantliisitta citrina, Gml. 



The colours are nearly the same as in the specimen described by me in the 

 Jour, fiir Orn. 1870, p. 252, but the feathers on the whole of the upper 

 parts are pale brownish, with narrow black lateral margins and the quills, 

 legs, and hind toe are considerably longer, as will be seen by the following 

 measurements, given in decimal parts of an inch : —

I recommend my ornithological friends in New Zealand to keep watch for 

 this stouter form in order to ascertain if it is a true species. 



No. 21, p. 109. Xenicus longii^eSf Gml. 



The figure in the Voyage of the Erebus and Terror (t.3, f.l), copied from 

 an original drawing of Forster, is totally incorrect and cannot be taken in 

 comparison. I have, therefore, no doubt but that Dr. Buller is quite right in 

 uniting X. sfolcesii with long{2:>es. 



No. 23, p. 109. Xenicus gilviventris, Pelz. 



Through the kindness of Dr. Hector I received the type of X. Iiaastly 

 Buller, which is undoubtedly synonymous with the above-named species. 



No. 24, p. 110. Instead of Oi'thonyx write Clitonyx ochrocephalus^ Gml. 



On the systematical position of this bird see my extensive paper " Ueber 

 die systematische Stellung der Neuseelandischen Gattungen Clitonyx Eeichb. 

 und Phyllodytes, Finsch "— (Jour. f. Orn. 1873, p. 393). 



P. 110. Before No. 25 place Fam. Paridce, and instead of Orthonyx write 

 Phyllodytes albicilla, Less. ; Finsch, Jour. f. Orn. 1873, p. 398. 



Having had the pleasure of becoming acquainted with this species through 

 the kindness of Captain Hutton, I was at once convinced that it is by no 

 means the northern representative of the foregoing species, as Dr. Buller says, 

 but that they belong to totally different families. 



No. 26, p. 110. Certhiparus must become Phyllodytes novcz-zealandice^ 

 Gml. ; Finsch, Jour. f. Orn. 1875, p. 397. 



No. 27, p. 111. SphenoQacus 2)unctatiis, Quoy. 



I have examined specimens from the Rakaia, received through the kind 

 assistance of Dr. Haast. 



No. 29, p. 112. Sphenoeacus rufescens, Bull. 



This is not the same as Sph. falvus. Gray, as suggested by me, but is a 

 very good species. I received specimens from the Chatham Islands through 

 Dr. Hector.
