To Leonard Jenyns 3 December 
36 Grt Marlbro’ St —
My dear Jenyns
I have been for some time intending to write to you, but I have been partly too idle and partly too busy.— Henslow tells me he hears a groan occasionally escape from you, when you mention my fishes; I ought to feel very thoroughly ashamed at this, but I am so very glad that you have undertaken to do what you can, that I am hardly able to pity even your groans.— I would sooner all the fish had rotted, than Mr Gray1 described them & with his exception, if you had not taken pity on them, they most surely would have remained for many a long year unlooked at and unnamed.— I understand, that you have made up your mind that some of the fish are undescribed.— If D’Orbigny’s Voyage2 is not in Public Library,3 you ought to urge Mr Lodge4 to get it; as it is most important work & will certainly contain some of my fish, at least some from the Patagonian coast. The Coquille’s Voyage5 possibly may contain some from the Falkland Islds — Henslow will deliver to you a portfolio of coloured drawings of fish, made for Capt. FitzRoy by the artists on board the Beagle.6
The locality of each is mentioned, it is just possible that where only one of a marked genus occurs at a place you might be able to identify it, in which case we might have a coloured drawings.—
I will have any or all the fish you think new lithographed.— You need not be in any hurry about the fish (without you want to finish it & say you have done all you can do) as the fish will be published last of the vertebrate animals.—
I will of course send you a copy of the firs〈t〉 number, when it appears in January:7 it will contain nothing but the description of Toxodon.—
I hear you have had a pony for some time, but that most unfortunately it has turned lame. I wish with all my heart I could see any near prospect of paying Cambridge & you a visit, but you would be surprised to know how many minutiæ this Govermt work has entailed on me.— There will be no comfort in such undertakings, without a law is passed to empower naturalists every now and then to hang an artist for an example.—
Believe me, my dear Jenyns | Most truly Yours | Chas. Darwin.—
CD is glad LJ is describing the fishes [for Zoology]; would not have permitted J. E. Gray to describe them. New species will be lithographed.
Suggests books; offers coloured drawings made by artist on Beagle voyage.
