Americana, ! from a specimen in Mr. Taylor’s collection obtained from Mexico. 
Though found in that country by several subsequent travellers, the bird would appear 
to be rather local in its distribution in Southern Mexico, being, according to Prof. 
Sumichrast *, confined to the alpine region, at the extreme limits of vegetation, on 
the lofty volcano of Popocatepetl; he doubts the accuracy of the locality “* Jalapa ” 
assigned to de Oca’s specimens ? *.

This peculiar genus comprises six species, which are distributed over the Nearctic 
Region, Europe, Madeira, and the Himalayas, two of them (or, including RB. cuvieri, 
three) being found in America. Both R. satrapa and R. calendula enter within our 
limits as winter migrants. One of the chief peculiarities of the genus lies in the nostrils 
being covered by small stiff feathers—a character which, though rudimentary in 
fh. calendula, is still present, rendering Cabanis’s generic term for it, Phyllobasileus, 
unnecessary.

Though Lichtenstein was the first ornithologist to describe this species, it was 
previously known to Wilson and others, who, however, failed to distinguish it from 
the European Regulus cristatus. Like R. calendula it has a wide range in North 
America, being, according to Dr. Coues, a more northern species upon the whole, as it 
is rare in the basin of the Colorado and the country lying to the southward 
i. satrapa passes the winter in the States, being found as far north as New England 
and Washington Territory at that season*; but those which are found in Mexico and, 
* Cordova has also been included, on M. Sallé’s authority, amongst the places where this species is found ; 
but no. 85 of that traveller’s list (P.Z. 8. 1856, p. 293) has no locality assigned to it, and may have been 
obtained in the upland region of the Volcano of Orizaba.
