From J. G. Forchhammer1 [15 November 1849]2
My dear Sir.
With the steamer Camilla which left Copenhagen some days ago, I have sent to You all the fossil peduncalated Cirrhipedes which our collection contains and inclosed You will find a letter from Prof. Steenstrup3 which will tell You about the changes which he thinks proper to make in his former destinctions. I have not separated those specimens which I could give You for Your own collection and I should be obliged to You if You would return them all with Your names; specifiing which of them You should wish for Your own collection.
Has sent all the fossil pedunculated cirripedes in the Copenhagen collection, together with a letter from Johannes Steenstrup concerning changes he believes are needed in the descriptions.
