so recently reached us that we must be pardoned for now making 

 upon it only the briefest remarks possible. According to Mr. Gas- 

 sings view. Prof. P. L. S. Miiller's edition of Linnseus^s ' Systema 

 Naturse/ published at Nuremberg between 1773 and 1776, 

 will effect a very great revolution in our nomenclature, so 

 much so that we think it expedient, in a future number of 

 this Journal, to go thoroughly into the subject, and reprint 

 from Mr. Gassings list the names, conferred by Miiller at this 

 period, which will have to take precedence of the appellations of 

 Boddaert even, and, of course, of later writers. We believe 

 Miiller's work to be extremely scarce, — at present we are not 

 even aware whether a copy of it exists in this country ; it will 

 therefore be the more incumbent upon us to place our readers 

 in possession of as much information about it as we can.

 though I should rather have expected P. sordidus so far north ; 

 I did not, however, procure specimens. My new Hypsipetes 

 niveiceps [Ibis, 1864, p. 424], from Swatow, also occurs in the 



mountains near Foochow, as does also a Nuthatch The 



young of Alcippe hninnea, Gould, like the young of A. morrisonia, 

 mihi (Ibis, 1863, p. 296), resembles the adult, but wants the 

 black streaks on either side of the hind neck. 



A word on Guckoos, and I have done for the present. The 

 Guckoo of the Tamsuy vicinity is a small species, a good deal 

 smaller than Cuculus kelungensis, mihi (Ibis, 1863, p. 394), and 

 mottled with black on the axillaries. It utters the notes " cooh- 

 cooh " very abruptly, and usually when perched on the top of a 

 conspicuous part of some tree. It is rather shy of approach. 

 I have distinguished my specimens of it, for the present, as C.
