LIST OF FISHES RECORDED FROM OKINAWA OR THE 

 RIU KIU ISLANDS OF JAPAN. 



By David Starr Jordan and Edwin Chapin Starks, 



of Stanford University. 



The Rill Kin Islands, known also as Lu Cliii or Lyii Kyu, in Japa- 

 nese as Okinawa, constitute a group of tropical islets, coral bound 

 and volcanic in origin, extending southward from near the Japanese 

 island of Kiusiu toward the island of Formosa. Little is known of 

 the fish-fauna of tliis region, except that it is fully tro]:)ical, composed 

 largely of forms having a wide distribution among the coral islands 

 of Polynesia, with some species characteristic of the coasts of south- 

 ern Japan and China. 



While in Japan, in 1900, Messrs. Jordan and Snyder obtained two 

 small but useful collections from these islands. One of these was 

 presented by Mr. Alan Owston, the well-known naturalist of Yoko- 

 nama; the other was purchased from Yonekichi Koneyama, a natural- 

 history dealer in Tokyo. The first collection was made up of small 

 fishes from the reefs of the large island of Katsuudake, on which is 

 Naha, the principal town of Okinawa, and from the smaller island of 

 Ishigaki at its town of Yaeyama. Koneyama's collection came from 

 the Naha market. From the Imperial Museum of Tokyo also several 

 specimens were received, from the island of Miyako (Miyakojima), 

 and from Naha, island of Katsuudake, through the courtesy of Dr. 

 Chiyomatsu Ishikawa. Some others were received from the Imperial 

 University through Dr. Kakichi Mitsukuri, and still others in the 

 Imperial Museum have been recorded by Ishikawa and Matsuiira. 



The collections in question were brought b}' Profs. Jordan and 

 Snyder to the Museum of Stanford University, and most of the new 

 species have been already noted in previous papers on the fish-fauna 

 of Japan. A series of duplicates is in the L^nited States National 

 Museum. Illustrations of a number of these species have appeared 

 in papers recently published in these Proceedings.
