My dear Sir

Judging from single specimens1 I should say than Larus hæmatorhynchus was one eighth smaller than fuliginosus

The 3 Galapagos species of Orpheus are much duskier colored than those from the continent— The continental species vary considerably in size, some running much larger & some much smaller than those from the Archipelago. Zenaida Galapagoensis is about 15 smaller than aurita

The Totanus fuliginosus is much more dusky than any other species we have in our collection— it is much the same size as other species of the genus2

The Breeding list is in progress3 Do you require the particulars of the Hybrids

I have the honor to be | My dear Sir | Your obedient Servant | Louis Fraser


The bird specimens referred to had been presented to the Zoological Society by CD on 4 January 1837 (see Correspondence vol. 2, letter from Emily Catherine Darwin, 15 [January 1837], n. 7).
For CD’s use of this information see Journal of researches 2d ed., pp. 378–81. Sulloway 1982 discusses CD’s collection of Galápagos birds.
Possibly a list of animals that had bred successfully in captivity in the Zoological Society’s gardens, see Correspondence vol. 3, Appendix IV.
