the most northern part of its great bend. Then turning along 
its south bank for 250 miles, he recrossed it at Ding-hu, and 
proceeded into Alashan, a wild and barren mountain-district, 
lying to the south of the Gobi. Here, we believe, most of 
his best zoological discoveries were made. In a second ex¬ 
pedition in 1872, Col. Prejevalsky succeeded in penetrating 
far beyond Alashan, through the little-known Chinese pro¬ 
vince of Kansu, to the large lake of Kokonor, the original 
aim of his journey. In a winter-journey from Kokonor he 
finally penetrated to the banks of the Upper Yang-tze, only 
500 miles from L’hassa, where only want of funds stopped 
his further progress. 
23. Rowley’s ‘ Ornithological Miscellany .’

The sixth part of Mr. Rowley’s f Ornithological Miscel¬ 
lany/ a work of the general character of which we have 
already spoken, contains the commencement of a memoir of 
much importance to English ornithologists. We have just 
spoken of Col. Prjeval sky’s f Travels in Mongolia/ and of 
the many zoological discoveries which he made; but the tech¬ 
nical portion of the work relating to the birds was not included 
in Mr. Morgan’s English edition. Aware of its importance 
to naturalists, Mr. Rowley has now had a translation of this 
part of it made by Mr. F. Carl Craemers, the first portion of 
which, embracing an account of 117 species met with by 
Colonel Prjevalsky in Mongolia, the Tangut country, and the 
solitudes of Northern Thibet, is included in the present num¬ 
ber of the ‘ Ornithological Miscellany/ with a promise of the 
remainder to follow. The plates of the original work are 
also faithfully reproduced. The new species described by 
Colonel Prjevalsky are :— Caprimulgusplumipes , from China; 
Ruticilla alaschannica, from the Alashan mountains; Calliope 
tschebaiewi , from the Kansu mountains; Pcecile affinis , from 
the Alashan and Kansu; and P. superciliosa, Lophophanes 
dichroides, and Merula kessleri , all from the Kansu mountains.
