To G. R. Gray [February 1841]
[12 Upper Gower Street]
My dear Sir
In the two last proofs, you have called one ground-woodpecker Chrysoptilus campestris & the second you left “Colaptes Chilensis Vigors”.— I have altered this to “Chrysoptilus Chilensis G. R. Gray”—1 Is this right.?— You need not look at any other part of this Revise.— Will you 〈plea〉se leave these sheets, as you 〈retu〉rn home.—
Yours most truly | C. Darwin
In a revise [of Birds] CD has altered "Colaptes Chilensis Vigors" to "Chrysoptilus Chilensis G. R. Gray". Is that right?
