95. The United States Expedition to Japan, under Commodore M. C. Perry, 

 1852-4, was not undertaken for scientific purposes ; and no special provision 

 was made either for collecting or describing objects of natural history. A 

 large number of shells, however, were obtained, and identified by Dr. Jay of 

 New York. In Vol. II. of the < Narrative of the Expedition, <fec.' (Washing- 

 ton, 1856, pp. 289-297) is given a list of Japanese shells, with descriptions and 

 figures of the (supposed) new species. The following are related to the mol- 

 luscs of the "West Coast f. Specimens of the most important may be seen 

 in the Cumingian Collection. 



* The M. mutabilis, described on the same page from Kagosima, is a Septifer; it is pre- 

 sumed that the learned author did not open a specimen. 



t The student should also consult, for related forms, the ' Mollusca Japonica' by Dr. 

 W. Dunker, Stuttgart, 1861 ; like all the other works of the same author, most valuable 

 for the patient care, accurate judgment, and enlarged experience displayed; but relating
