at tip, slightly notclied, soniouhat obtuse ; lower slightly recurved 

 at the point: nostrils basal, lateral, concave, longitudinal, covered 

 by a membrane : tongue cartilaginous, bifid at tip. Tarsi longer 

 than the middle toe, smooth ; feet naked ; inner toe free, hardly 

 longer than the hind one; lateral toes equal. Winos short, 

 rounded ; spurious feather very short; second and third primaries 

 longest. Tail short. 



Female hardly diflering in plumage from the male : young 

 more tinged with reddish. Moults annually. Plumage imperme- 

 able (water-proof.) 



Solitary. Lives near brooks and clear rivulets, diving and walk- 

 ing on the gravel bottom, often entirely under the water, which 

 appears to be its favourite element. Feeds on aquatic insects, 

 especially small Crustacea. Builds in the vicinity of rivulets, hiding 

 its nest carefully. Flight rapid, straight, skimming the surface 

 of the water. Voice feeble, shrill. 



Inhabits the north of both continents. Composed of but two 

 intimately allied species, both probably Asiatic, though one is 

 found in Europe and the other in North America. Remotely 

 allied to the order Grallce by its habits, (which are still more 

 aquatic than those of true water-birds,) and by the nakedness 

 that prevails around the head ; but belonging decidedly to this 

 family (Canori) where it is related especially to Turdus^ Mijio-

 Inhabits near the Rocky mountains, on the Athapescow Lake, 

 probably north-eastern Asia. 



Obs. This species (which we do not hesitate in referring to 

 Temminck's Cinclus Pallasii^ notwithstanding its conjectured 

 locality, which at first led us to consider it as new, under the 

 name of Cinclus unicolor), is the more interesting, iu as much as 

 the European species was the only one well known of the genus, 

 which I noted, in my " Observations on the Nomenclature of
