Discusses Balanus unguiformis. Promises to return specimen.
Down Farnborough Kent
My dear Forbes
The Balanus from Bembridge, Barton & Headon beds is the same species B. unguiformis of Sowerby. The Headon specimens, about which I doubted are the best characterised & are so perfect, as to be worth preserving. The specimens shall be taken care of, & returned to you hereafter with others that I have of yours.—
Most truly your's | C. Darwin
- f1 1472.f1CD described these fossil specimens from Eocene formations of the southern British coast and the Isle of Wight in Living Cirripedia (1854): 296–8. He included short descriptions of the fossil forms of Balanidae and Verrrucidae in Living Cirripedia (1854) because at this stage he was unsure that the Palaeontographical Society would publish a work on the fossil species of these groups.
- f2 1472.f2Forbes was among those thanked in the preface of Fossil Cirripedia (1854) for having provided specimens.
