Summary:

At the suggestion of J. D. Hooker CD offers his opinion on the value of a proposed collection to be made at the Galápagos. The display would not be attractive or appealing to amateurs in natural history, but the scientific value of good collections of every species would be very great if those of each island are rigorously kept separate.

Summary:

Obliged for his memoir ["On the avifauna of the Galapagos", Trans. Zool. Soc. (April 1875)]. His surprise that the birds from the different islands prove so similar. Comparison of the habits, nests, eggs of the commonest species of each island would throw a flood of light upon variation.
