TO A. HANCOCK, ESQ. 253 



Loven's Cirripede, of whicli I had not heard. I should be most 



grateful for a transcript of the paper and drawing, or if the book 



be not above 2 lbs. or too precious could it not be sent, and I 



would gratefully repay postage, and thus save Mr. Alder the 



trouble of transcribing, to whom pray give my sincere thanks. 



I have in my collection this Cirripede as I suspect; it is like an 



Otion,* and from not having calcareous valves might be called an 



Alepas ; but, strange as it would appear to any one who had not 



studied the internal structure of these animals, it is not even one 



of the Pedunculata, but belongs to the sessile division, and forms 



a new genus between Tubicinella and Coro^ula. I should have 



been very sorry to have overlooked Loven's description. 



I presume you have a superabundance of materials, but if at 



any time you would like to have my small collection of naked 



MoUusca, made during my circumnavigation, they are at your 



service ; but I fear specimens preserved for many years in spirits 



must be almost useless. I think there are some new genera 



amongst them. Once again allow me to thank you cordially for 



the very kind manner in which you have taken my requests, 



and believe me, dear Sir, 



Yours sincerely obliged, 



C. Daewin. 

 To A. Hancock, Esq. 



I see in the Athenaum they have omitted to express how 

 valuable I thought your discovery, and how interesting your 

 whole paper. I am very curious to see what you say about the 

 palpi. I could not follow the reading aloud of this part, but if 

 I understood right, the palpi are wonderfully different from 

 anything I have seen in the Cirripedia. I think it possible that 

 Alcippe and Arthrobalanus may turn out distinct orders. The 

 metamorphosis is certainly different. My larva has no thoracic 

 legs, where yours has ; mine is binocular, yours uniocular, etc., 

 etc. Yet the three pairs of cirri, the great labrum, and habits 

 are certainly strong points of resemblance. 



I ought to apologise for the length of this letter.
