Bewick’s Swan, white ; bill, yellow at the base posterior to the 
nostrils, 18 tail feathers. 
ec This swan breeds on the sea coast, within the 
Arctic circle, and is seen in the interior of the fur 
countries in its passage only. It makes its appearance 
amongst the latest of the migratory birds in the spring, 
while the trumpeter swans are, with the exception of 
the eagles, the earliest. It winters, according to Lewis 
and Clark, near the mouth of the Columbia.* Captain 
Lyon describes its nest as built of moss peat, nearly six 
feet long, and four and three-quarters wide, and two 
feet high, exteriorly; the cavity, a foot and a half in 
diameter. The eggs were brownish white, slightly 
clouded with a darker tint.”- — Richardson . 
CLANGULA, GARROT. 
45. CLANGULA BABROWII. ROCKY MOUNTAIN GARROT. 
Head f and upper part of the neck , pansy purple , 
with a large crescentic white mark before each eye. 
White speculum separated from the band on the coverts 
by a black stripe . Inhabits the Rocky Mountains. The 
specific name is intended as a tribute to Mr Barrow’s 
varied talents, and his unwearied exertions for the pro- 
motion of science. Mr Swainson remarks, on the 
subject of zoological nomenclature, that “ No monu- 
ment of marble or brass is so lasting as this. It is the 
only way of perpetuating the memories of true zoolo- 
* “ The swans are of two kinds, — the large and small. The 
large swan is the same with the one common in the Atlantic States. 
The small differs from the large only in size and note ; it is about 
one-fourth less, and its note is entirely different. These birds 
were first found below the Great Narrows of the Columbia, near 
the Chilluckittequaw nation. They are very abundant in this 
neighbourhood, and remained with the party all winter ; and, in 
number, they exceed those of the larger species in the proportion 
of five to one.” — Lewis and Clark, Journ. &c.
