Has sent CD some cirripedes and notes which he hopes will be of use. Gives details of occurrence and source of some of the specimens.
My dear Sir,
I have to return you my thanks for your obliging letter of the 31
It will give me much pleasure if the notes & specimens of Cirripedia, which I
sent you are of any use to you in the preparation of your work
which is not only much needed but will by all accounts be far superior to any which has
yet been published on the subject both as respects the soft parts and metamorphoses of
these interesting creatures as also their shells or calcareo-crustaceous coverings. The
notes are entirely at your service as I shall not want them The specimens may be sent to
I will now endeavour to answer your queries seriatim
5 I have taken B. Sulcatus at Exmouth & Plymouth, and believe it to be common to all our coasts.
I agree with you as to the inconvenience of burdening your work with synonymes & the extreme difficulty of making them out but as it will give a fresh starting point I think Naturalists might expect the Synonyms to be elucidated and given although not repeated ie. not to give every synonym in every hitherto published work but only those which are distinct. This however will be left to your better judgment.
Believe me to remain dear Sir | Yours sincerely | J. G.
Charles Darwin Esq
P.S. I shall feel obliged by your labelling my specimens with the name you intend to adopt or use, if it does not give you too much trouble—

- f5 1452.f5William Clark of Exmouth. He contributed many articles to the Annals and Magazine of Natural History between 1830 and 1850, particularly on molluscs. CD also considered that B. amphitrite was not found in British waters (see Living Cirripedia (1854): 241).
- f6 1452.f6Balanus crenatus is described in Living Cirripedia (1854): 261–8. In the section ‘Range, habits, &c.’, Jeffreys's collection is cited as containing a specimen from ‘forty-five fathoms’.
- f7 1452.f7Balanus spongicola is described in Living Cirripedia (1854): 225–6. Jeffreys's specimen was the largest CD examined, ‘.6 of an inch in basal diameter.’
- f8 1452.f8Balanus improvisus (Living Cirripedia (1854): 250–3). Jeffreys's specimen is mentioned on p. 252.
- f9 1452.f9Balanus sulcatus was given as a synonym for B. porcatus (Living Cirripedia (1854): 256). This cirripede is generally found on the coasts of Scotland and Ireland. CD recorded that: ‘Mr. Jeffreys, who knows this species well, has found it common on the extreme southern shores of England’ (ibid., p. 258).
- f10 1452.f10In the introduction to Living Cirripedia (1854): 2, CD stated: ‘I have given much fewer synonyms than is usual in conchological works; for it is impossible to recognise with any approach to certainty, several even of the common European forms, in the short descriptions given by most authors’.
