Adams, 1872: “This beautiful species, at present unique, is stated to have been obtained from the stomach of a fish, but is in a good state of preservation.” Transcription of a letter from G. B. Sowerby (3rd) to J. C. Melvill dated August 9th 1882, held in the Melvill-Tomlin archive: 9 Fountain Street Whitstable August 9th 1882 Dear Melvill Your letter has been forwarded to me here, where I am staying with my family until next Tuesday or Wednesday. By a curious coincidence a letter came to me by the same post as yours from M. de Robillard of Mauritius, in which he mentions the Conus dusavelli (having heard from Sir David Barclay that I had acquired it). I was told that it had originally changed hands for £80 but he does not say so. He says - “The shells previously belonged to me. I sold it to the late M. Du Savel who was an ardent collector of shells for £40. I procured the shell of a fisherman, who found it in the stomach of a fish taken at the depth of 60 fathoms. As this shell was obtained by mere chance it is pretty certain that it will not be found again, unless you have a fish well trained at your disposal! Which would be a miracle.” For my own part I think the chance of the shell turning up again are very remote. The fact of its having remained unique for more than 10 years in spite of constant search in the very place where it was found is very much in its favour, and I should not be in the least afraid to hold it. I could easily have sold it some time ago, but I am determined not to let it go out of the country. At the same time I am not at all disposed to reduce its price which, as costly shells go, I think moderate. When Sir David Barclay first returned from Mauritius he was tempted by the offer of high prices to dispose of several shells which he had taken himself, thinking that he was going back and knows the exact spots where he found them, he would be able to get others, he was however mistaken. One was that Ovulum longirostratum, which you got from the Taylor collection, and for which he said afterwards he would have given any money. Another was the Cypraea barclayi for which Reeve gave him £15 and which he sold to Miss Saul, and no other specimen has ever been found. The Murex barclayi Sir David parted with for Mrs De Burgh thinking he would get it again, but all these years he has never been able to lay his hands upon one. I think the Conus dusavelli only having been found in the stomach of a fish, is even less likely to turn up again than any of these. I am not at all anxious to dispose of the shell, but when I do I should like it to settel down in your collection. Yours sincerely G. B. Sowerby Jr
