160 LOO CHOO MOLLU8K8. 



APPENDIX II. 



LIST OF MOLLUSCA IN THE COLLECTION OF FREDERICK STEARNS 



FROM THE MIDDLE Loo CHOO ISLANDS, WITH DESCRIPTIONS OF 

 NEW SPECIES. 



The species listed below were collected for Mr. Stearns by Morizo 

 Seta during 1891, 1892. Part of them were determined by Mr. 

 Stearns, part by Mr. Pilsbry, the latter being indicated by an 

 asterisk (*) following the species names. 



In this list the name Yaeyama Jima (" many-peaked island") is 

 used for the largest of the middle Loo Choo group, often known as 

 Okinawa. We believe the same term has also been applied to 

 another island of the group. 



A list of mollusks from the middle Loo Choo Is. has been pub- 

 lished by Dr. O. Bottger (Nachrichtsblatt des Deutschen Malako- 

 zoologischen Gesellschaft, 1892, p. 153). A recent general account 

 of the physical and political features of the group may be found in 

 The Geographical Journal, V, April, May, June (London, 1895) by 

 Professor Basil Hall Chamberlain, of the Imperial University of 

 Japan. 



The most remarkable diversity exists in the etymology of the 

 name of these islands, but the form " Loo Choo " or its phonetic 

 equivalent " Luchu " seems preferable for English speaking peoples. 



The malacological fauna of this chain of islands seems to be mod- 

 erately homogeneous as far as known.
