2 BULLETIN 164, UNITED STATES NATIONAL MUSEUM 



years of research at the United States National Museum, without 

 whose collections no adequate study can be made of faunas with 

 Arctic elements. I wish also to express my indebtedness to Dr. Au- 

 gust Foerste for his many helpful notes and suggestions, particularly 

 in my study of the cephalopods. 



I further wish gratefully to acknowledge my obligation to Prof. 

 H. Yabe, of the Tohoku Imperial University, from whom I have 

 received much encouragement and help in my field work. Likewise 

 I am indebted to S. Iwata, president of the Iwata Institute of Plant 

 Biochemistry in Japan, for considerable funds donated to carry on 

 my studies. Similarly, the Scholarship Foundation of the South 

 Manchuria Railway Co. rendered me invaluable financial assistance. 



Finally, I must express my hearty and sincere recognition of the 

 encouragement given me by the late Dr. Charles D. Walcott, secre- 

 tary of the Smithsonian Institution. It was his inspiration that led 

 me to continue my geological work in South Manchuria, and 

 eventually to come to America to complete my studies. 



BIBLIOGRAPHY 



The following bibliography lists the papers dealing with the 

 stratigraphy and paleontology of Manchuria and other Chinese 

 localities. A few Korean references also are included. Papers that 

 do not deal exclusively with Asia, in which genera present in my area 

 were first described, or wherein mention is made of species closely 

 related to the Asiatic forms, are not included in the list. Such refer- 

 ences are, of course, included in the synonymy of the particular 

 species.
