Asks CL whether he has talked with John Murray concerning 2d ed. [of Journal of researches].
Mentions conversation with Hugh Cuming about South American shells. Has had G. B. Sowerby (elder) look at some specimens.

My dear Lyell
I find that d'orbigny (Voyage dans l'Amer. Merid. Partie Gèolo. p. 226) describes ten Silurian fossils from the eastern line of the Bolivian (or Upper Peru) Cordillera; he states that they are all distinct, names them, but says they present the strongest general resemblances to those of Europe.— p. 230 describes seven Devonian fossils with same remarks.— p 239 describes 23 Carboniferous fossils with same remarks; two, however of these 23 perhaps are not new, for I see that they are not described by him, viz. Natica antisinensis & Spirifer Roissyi— Amongst his Cretaceous fossils he states that 5 are common to the Paris Basin.— There is a copy in the Athenæum, if you wish further to refer to it.
I forgot, when with you on Thursday, to ask you, if you have any opportunity, to have another talk with Murray about my Journal.—
After being with you, I went & had a long talk with M
Believe me | my dear Lyell, | C. Darwin

CD considered the distribution of Tertiary shells an important indicator of climate during that period (South America, pp. 134–5).
