parts of the Palearctic region, its southern limits extending in Asia to the Himalayas, 
and in Africa to the Atlas Mountains. 
The habits of the species are well known, and have been fully described by writers 
on European and North-American birds. The number of recognizable species is about 
thirteen, an account of which will be found in ‘ The Ibis’ for 1867.

Though the Mexican Dipper was first brought into notice as an American bird by 
Swainson, who described Bullock’s specimen}, it was supposed by Bonaparte to be the 
same as the Asiatic Cinclus pallasi, and for some time passed under that name *. 
It has an extensive range in North America, reaching from the Yukon throughout 
the Rocky Mountains, to Southern Mexico and probably to Guatemala. It seems 
to be resident wherever it occurs, even in the most northern parts of its range, 
where Mr. W. H. Dall found it in the height of winter’. Its habits, which 
quite resemble those of the common European Cinclus aquaticus, have been fully 
described by writers on North-American birds?*, and need not be repeated here. 
From Mexico we have but few details concerning it; Prof. Sumichrast ® places it 
amongst the birds of the alpine region of Orizaba, but states that it follows the water- 
courses of the Cordillera into the temperate region as low as 3300 feet above the sea, 
its range in altitude extending upwards to an elevation of 7200 feet. In Guatemala 
we only once met with Dippers, when, on the 5th September 1862, a pair were 
observed in a mountain-torrent in the Cordillera above Totonicapam, at an elevation of 
about 10,000 feet above the sea. One of these was shot, but lost in the stream. Not 
having examined these birds at less than a gunshot distance, we cannot say whether 
they actually agreed with the Mexican C. meaicanus; but we observed that their 
plumage was of one colour, as in the northern bird. 
Cinclus mexicanus has received several synonyms, which will be found enumerated 
in Dr. Coues’s ‘ Birds of the Colorado Valley’®.
