dreams of creeping about bushes, or even entering them after the 

 manner of Warblers. The remark may well be applied, however, 

 to the next species that follows, Lusciola cyanura. 



" Petrocincla manilensis. I have repeatedly shot specimens of 

 this bird without a tinge of ferruginous on the under-parts, and 

 undistinguishable from examples of P. pandoo received from Mr. 

 Blyth; I cannot therefore help agreeing with that gentleman, 

 in thinking that both of the so-called species may be referred to 

 P. cyanea, the red tints of the belly and vent being probably 

 attributable to certain climatal causes, as is the case with the 

 different varieties of Cuculus tenuirostris. 



" Ixos hamorrhous, plate 6. The crest given in this plate is a 

 perfect mistake. The bird has no crest, the black crown-feathers 

 being but of ordinary length. 



" Gallinula chloropus. I once saw this bird at Amoy. I have 

 since procured a pair at Formosa. 



" Charadrius pluvialis. This must be a mistake in identifica- 

 tion. The Chinese bird, of which I have seen a large number, 

 is undoubtedly referable to C virginicus. 



" Sterna minuta. This bird is found occasionally on the coast 

 of China ; but all the small Terns I have yet seen in Formosa 

 are of some other species — perhaps S. nereis of Gould. One 

 would expect to find the Formosan species at Loochoo.*' 



We are indebted to the courtesy of Sir William Hooker for 

 the inspection of a valuable paper furnished to the newly esta- 

 blished Institute of Rupert's Land by the editor of * The Nor'- 

 Wester,' a journal published at Eed River Settlement. The 

 writer, the Rev. W. W. Kirkby, therein describes a journey 

 lately performed by him from the Mackenzie River to the Youcan 

 or Jukon. Besides affording some interesting information re- 

 specting the Indian tribes, to which this gentleman is a mis- 

 sionary, he gives us the first account we have received of the 

 energetic collector of the Smithsonian Institution, Mr. A. Ken- 

 nicott, whose expedition was announced by us two years ago 

 (' Ibis,' 1860, pp. 309, 310), and whom he met with at the fort 

 situated at the junction of the Jukon and the Porcupine Rivers. 

 Mr. Kirkby proceeds to say that " he (Mr. Kennicott) delighted
