in A. apcxfulva of the Koolau Range as in A. uiusielina of the 

 Waianae Mountains? 



During the 7 years I spent in Hawaii studying Achatinella I was 

 greatly helped in acquiring a background for the present work by 

 Dr. C. M. Cooke, Jr. Working under Dr. Cooke, I also learned 

 many methods of studying and preparing material which greatly 

 facilitated my work. I am also indebted to Dr. E. A. Andrews, 

 Dr. Henry A. Pilsbry, Dr. H. B. Baker, and Dr. Ernst Mayr for 

 criticisms and advice in the preparation of the manuscript. Dr. F. Ray- 

 mond Fosberg was most helpful in identifying all genera of Hawaiian 

 plant names given by various collectors of shells. I also wish to 

 express appreciation to the following for various courtesies and 

 favors : Dr. Paul Bartsch, W. J. Clench, W. T. Caiman, Col. A. J. 

 Peile, J. R. le B. Tomlin, G. S. Robson, Dr. Paul Galstoff, Dr. Gilbert 

 D. Harris,. Dr. C. E. McClung, Dr. Peter H. Buck, Dr. Herbert 

 Gregory, the Trustees of the Bernice P. Bishop Museum, and the au- 

 thorities of the United States National Museum. 



The gr®und work of this paper was done at the Bernice P. Bishop 

 Museum in Honolulu, the writing of the paper was carried on at 

 the United States Bureau of Fisheries at Woods Hole, the Zoological 

 Laboratory of the University of Pennsylvania, the Zoological De- 

 partment of the Johns Hopkins University, and the Zoological 

 Department of Barat College, Lake Forest, 111. I wish to thank these 

 institutions for granting me facilities for work. 



PLACE NAMES OF THE KOOLAU RANGE 



Most of the names of the valleys or gulches of the Koolau Range 

 are well known, but the names of some have never appeared on a 

 Government map. Other gulch names have not been known, and 

 still other gulches, although their names are well known, contain large 

 subgulches that need to be designated by some name in order that 

 localities may be described exactly. 



Pilsbry and Cooke (1912-1914, p. 277) published a rough dia- 

 grammatic sketch map of the northwestern half of the Koolau Range 

 in which they included the new names Kalaikoa, Ahonui, Main 

 Poamoho, Central Poamoho, West Poamoho, Kawaihalona, and 

 Luapo. This map was compiled from field notes made by Irwin 

 Spalding and is the first published map showing the approximate 

 regions occupied by colonies of AcJiatinella. Many of these names 

 do not exist on the advance sheets of the United States Geological 

 Survey topographic sheets of Oahu, Hawaiian Islands, 1/20,000, 

 which form the standard map I used for plotting all localities of
