wing-bands are merely indicated. The bill is very characteristic. It is somewhat weaker at the base 
than in L. hornemanni, but longer and remarkably darker in all seven specimens. 
“The bird figured by Dresser on the second plate (lower figure) belongs here, and is by no means the 
young of L. hornemanni, as supposed by Dresser.” 
[This description accords well in every particular with the dark summer stage of Hygiothus linaria 
holbélli, described in 1861 by Dr. Coues as Z. rostratus, the type of which came from Greenland.—R. R.]
