Dated on the assumption that this is the list of questions referred to in the letters to S. P. Woodward, 3 June [1856], and from S. P. Woodward, 4 June 1856. It seems probable that CD posted the questions to Woodward, as requested in the letter from Woodward, 4 June 1856, rather than delivering them in person, as was first suggested in the letter to S. P. Woodward, 3 June [1856]. Woodward wrote his answers on the list of questions and returned it to CD, probably during CD’s next visit to London on 18–21 June. Most of the questions posed in the letter were first noted in the margins of CD’s copy of Woodward 1851–6, now in the Darwin Library–CUL.
The page numbers refer to Woodward 1851–6. Woodward wrote notes on the list and then returned it to CD. CD subsequently wrote remarks next to Woodward’s notes.
CD underlined this sentence again and overwrote the second ‘?’ in brown crayon.
Woodward added ‘= Buccinum — antarcticum’; under ‘antarcticum’ he subsequently wrote ‘[=Pisania]’. He also wrote ‘Buc. Donovani’ in pencil, then crossed this out in ink. CD drew a line through ‘Chrysodomus (p 109)’ in pencil. At the bottom of the page, keyed to this passage, Woodward wrote: Fusus Fontainei D’Orb. p. 377– — Zealandica Q & G. =Chrysodomus (Neptunea) all in Brit. M. — dilatata Q & G. teste Adams. [DIAGRAM HERE] “Buccinum” antarcticum, Falklands, = Pisania–Bivon. operc. claw-like. —— ligatum &c Cape = Cominella, Gr. operc. like Turbinella Woodward refers to Orbigny 1835–47 and Quoy and Gaimard 1830[–4]. Next to this, CD wrote ‘Used’ in pencil.
Hugh Cuming. CD wrote ‘Ask’ in pencil before Cuming’s name.
Woodward underlined CD’s ‘aberrant’ and added ‘aberrant’ after ‘New Zealand.’ and ‘aberrant U.S. Fusus cinereus (p. 380) is called Trophon at p. 359.’
Woodward added ‘a New Zealand shell in the Brit. Mus. is referred to this genus’. CD added ‘(?)’ after this in pencil.
Woodward underlined ‘Falkland Isld.’ and added ‘(D’Orb.)’. He refers to Orbigny 1835–47.
Woodward underlined ‘New Zealand’ and wrote: ‘A new sp. lately sent by McGillivray from the south (Feejees?)’. CD added ‘?’ in pencil over Woodward’s ‘?’ and wrote ‘ancient form’ in pencil at the beginning of this section.
Woodward wrote ‘typ.’ after ‘Crenella’ and then added ‘A minute sp. in Cuba (p. 473) Crenella (Forbes, including Lanistes, Sw.)’. Following ‘New Zealand.’, Woodward added ‘Brit. U. Green-sand’.
After this, Woodward wrote: ‘Y. Eightrii (Gould) Sandwich I. ?? Y. sp. p. 270.’
Woodward answered: ‘The Brazilian sp. p. 379, (L. cultrata, Cumana & L. tellinoides) are scarcely the same genus— Adams will give them a new name—’. The reference is to Adams and Adams [1853–]1858.
Woodward crossed out ‘(no S. Habitat given)’ and wrote: ‘A. longirostris, D’Orb p. 378. Falklands. a single valve, & that lost. A. bilunulata, Florida p. 380.’ He also underlined ‘Canaries’ and added ‘A. fusca also Medit.’
CD refers to E. Forbes 1856. Woodward added after ‘Patina’: ‘(Leach) = Nacella, Schum. 1816. Celtic & Lusitanian—not Arctic N. cymbularia Fuegia—’. CD added, in pencil: ‘(A species very like at Cape.)’.
Woodward responded: No! Monoceros calcar?? Dieffenbach (Gray) —— terullatus CD underlined Woodward’s ‘No!’ three times, and in his copy of Woodward 1851–6, 3: 371, CD wrote next to this genus: ‘No’.
Woodward wrote: ‘certainly wrong. see p. 130.’ Woodward 1851–6, 1: 130, reads: ‘Australia and New Zealand; where alone it occurs sub-fossil.’ George Brettingham Sowerby described CD’s fossil shells for South America.
In answer to CD’s question, Woodward wrote: ‘Swan R—Tasmania—Sandy Cape.’ Woodward underlined CD’s ‘page wrong’ and added: ‘p. 144 is right.’
Woodward crossed out all this sentence except ‘Modiolarca trapezina’ and added: ‘is common to Fuegia & Kerguelen’. CD later wrote in pencil: ‘(adheres to floating seaweed.’, presumably following the description in Woodward 1851–6, 2: 266. He also added a large exclamation mark in pencil after his original query. CD later crossed the letter up to this point in pencil.
Woodward wrote: British freshwater shells in N. India. in U.S. 6 sp. p. 399. p 384, 18 British freshwater shells range to Siberia (Limnæidæ in N. America.) Brit. F. W. shells in Tibet— Limnæa stagnalis, peregra, auricularis truncatula? Valvator piscinalis — Corbicula consobrina — Cyclas rhomboidea, Say = Paddington Canal! —— partrenseia Say. Ohio = Cornea? After ‘Cornea’, CD wrote ‘British’ in pencil.
Woodward responded: ‘Yes’. CD refers to Augustus Addison Gould’s monograph on the Mollusca collected during the United States Exploring Expedition (A. A. Gould 1852–6).
CD added in pencil ‘in Pacific’ after ‘islds’. Woodward added another ‘?’ and commented: ‘ “Helix similaris is found wherever the coffee plant grows; H. vitrinoides in like manner accompanies the Arum esculentum” Gould.’ CD refers to Pfeiffer 1848.
Woodward drew the following diagram to illustrate his point. [DIAGRAM HERE] C B A
CD underlined ‘individuals’ in pencil. Woodward wrote: ‘Yes! This is not my experience only—it is the conviction of all collectors.’
Woodward wrote: ‘There are no recent sea-shells in Eocene strata—but there are land & freshwater sp. e.g. Helix labyrinthica & Melanopsis buccinoides. The Genera of recent fr. water shells date back furthest.’ CD added in pencil: ‘than even land-shells.’
Woodward wrote: ‘Cephalopoda—marking organic eras’.
Woodward answered: ‘Black Sea p. 365. Britain p. 357..’
Woodward added: ‘W. Indies p. 379. Mass.— S. Carolina p. 380.’ and ‘F. perversus B. of Campeachy.’
Woodward responded: ‘The 2 Mazatlan sp. are correct. (see Cuming’s Col.) For Moreton B. I have no authority but Petit de la Saussaye in Journ. Conch.’ Woodward refers to the Journal de la Conchyliologie, the first four volumes (1850–4) of which were edited by Jean François de Paule Louis Petit de La Saussaye. After this, CD wrote in pencil: ‘Fulgar thinks American. Mercenaria unimportant genus’. He also added in pencil: ‘In eocene beds greater resemblance in F.W. & L shells than in sea-shells.’ and ‘Has some evidence that Aralo-Caspian was miocene’.
