To J. S. Bowerbank   24 February [1849]

Down Farnborough Kent

Feb 24th.

My dear Sir

I am very much obliged for the Scalpellum-fragments. The Plumularia shall be returned to you hereafter; I may want to look at base.—1 The Acasta’s are grand & seem to me quite new; but I know nothing of the genus as yet: there are quite sufficient specimens.2

I thank you sincerely for all your kindness & pray do not forget me, when you are going over your Sponges.

My work progresses slowly & in April I intend going for two months to Malvern to see if I can do my health any good.

Yours very sincerely | C. Darwin


A genus of feathery, branching colonies of hydrozoan polyps which have a protective horny covering. CD may have wished to compare the mode of attachment with that of the pedunculated barnacles.
Bowerbank provided CD with specimens of Acasta attached to sponges in his collection (see letter to J. S. Bowerbank, [January – August 1848]).


Thanks him for cirripede specimens.
