30. In the Voyage of the Astrolabe to the Australian and East Indian 

 Seas during the years 1826-1829, of which the " Zoology" was published by 

 MM. Quoy and Gaimard, Paris, 1830-35, there does not appear to have 

 been a single species collected identical with any from N. America. A list 

 of the MoUusca is given by Menke in the Zeit. f. Mai. for March 1844, 

 pp. 38-48. The same result appears in East Indian and Polynesian voyages 

 generally, which therefore have not been collated. 



31. In the "Description of the Cirrhipeda, Conchifera, and Mollusca in 

 a Collection formed by the Officers of H.M.S. Adventure and Beagle, em- 

 ployed between the years 1826-1830 in surveying the southern coasts of 

 S. America, including the Straits of Magalhaens and the coa.st of Tierra del 

 Fuego, by Capt. Philip P. King, R.N., F.R.S., assisted by W. J. Broderip, 

 Esq., F.R.S.," given in the Zool. Journ. vol. v. 1832, pp. 332-349, occur 

 very unexpectedly descriptions of the following species : — 



No. 44. Ampullaria Cumingii. Is. Sabago, Bay of Panama, in a small hill stream.

32. The most comprehensive and accurate materials for the knowledge of 

 the tropical Pacific fauna, are to be found in the collections made by Hugh 

 Cuming, Esq. In the year 1827 that gentleman set out on his first great 

 conchological voyage, and remained till 1830, exploring the West coast of 

 America, at various stations from Chili to the Gulf of Fonseca or Conchagua, 

 in lat. about 13° N. He also visited various of the Pacific Islands, and 

 especially the Galapagos group. Mr. Cuming is the first collector on record 

 who took notes, as accurate as was thought necessary, of the results of his 

 dredgiugs. It is cause for the greatest regret that a systematic account of 

 this expedition has never been published. The new shells brought home 

 have indeed been to a great extent described in the Proc. Zool. Soc. and 

 figured in the Monographs of Sowerby and Reeve. Of these the particulars 

 of station and habitat have been recorded. But not only has the student to
