Mountains, at considerably higher latitudes. But it was not 
to be expected that a Mexican species should extend so far 
north as the Athabasca Lake, where our specimen was pro- 
cured. The circumstance is, however, the less surprising in 
birds of this genus, as their peculiar habits will only allow 
them to live in certain districts. The case is similar with the 
dipper of the old continent, which, though widely dispersed, 
is only seen in mountainous and rocky countries. Though we 
do not see any improbability in the American species inhabit- 
ing the eastern Asiatic shore, we prefer believing that the 
specimens on which '’emminck established the species, and 
whose supposed native place was the Crimea, were in fact 
American. ‘The two species are so much alike in size, shape, 
and even colour, as to defy the attempts of the most deter- 
mined system-maker to separate them into different groups. 
The single species of which the genus Cinclus had hitherto 
consisted was placed in Sturnus by Linné, and by Scopoli, 
with much more propriety, in Motacilla. Latham referred 
it to Turdus. Brisson, mistaking for affinity the strong and 
curious analogy which it bears to the waders, considered it as 
belonging to the genus Tinga (sandpipers). Bechstein, Illi- 
ger, Cuvier, and all the best modern authorities, have regarded 
it as the type of a natural genus, for which they have unani- 
mously retained the name of Cinclus, given by Bechstein, 
Vieillot alone dissenting, and calling it Hydrobata. This 
highly characteristic name, notwithstanding its close resem- 
blance in sound and derivation to one already employed by 
Illiger as the name of a family, appears to be a great favourite 
with recent ornithologists, as they have applied it successively 
to several different genera, and Temminck has lately attempted 
to impose it on the genus of ducks which I had named 
Fuligula. In my system, the genus Crnclus must take its 
place in the family Canorz, between the genera Turdus and 
Myiothera. 
The dippers, or water-ouzels, are well distinguished by their 
peculiar-shaped bill, which is compressed-subulate, slightly
