Down Parnborough, Kent. 

 My dear Sir, 



I have to thank you sincerely for many things. Your 

 specimens arrived quite safe. I have as yet taken only a cursory 

 glance at them; for I have an odiously tedious job of compiling 

 long generic descriptions from my specific descriptions. When 

 I have done in a fortnight's time, I vs^ill enjoy the treat of 

 having a good inspection of Alcippe. I hope by that time your 

 paper will be out, as it will save me much time in comparing 

 every part with common Cirripedia ; indeed I will wait till I 

 can get the number with your paper. It is an immense time 

 since I have seen a new form of Cirripedia. At the same time 

 I will look over my MoUusca, and my few notes made at the 

 time ; and if they turn out of the slightest interest to you, I 

 shall be heartily pleased by your acceptance of them. I will be 

 careful of the specimens of Alcippe. Your sketches are very 

 spirited. The Cirripede from Australia is the Ilia Cuvieriana 

 (= /. quadrivalvis, Cuvier) ; that from Madeira is an unnamed 

 species, which I have unwillingly been compelled to make into 

 a new and insignificant genus. I have called it (supposing name 

 be not used) Machairis celata"^' (from being encrusted with bark 

 of the Antipathes). If you have any other Cirripedes from foreign 

 localities, and would allow me to examine them, it would be of 

 great service to me. 



"Will you please to give my sincere thanks to Mr. Alder for 

 the specimens, and for the great trouble he has taken in copying 

 Loven's paper. It is a most interesting Cirripede, and the type 

 of a new family or order, for it has no relation to Alepas, the 

 animal of which I know well. I must write to Loven ; his de- 

 scription is unfortunately short. Will you add to your kindness 

 by some time asking Mr. Alder to what place the Eoyal Academy 

 of Sciences given in the title belongs. Lady Lyell translates the 

 title as * Extract from a Eeview of the Trans, of the E. Acad, of 



» = Oxynaspis celata, Darwin.- Monog. of Cirripedia, Bay Soc, 1851, p. 134.
