the world have hclpcd to complete this study either by answering
lctters or sending specimens. AINO I received much information and
help from Hcitwtists in the various corintrics of Asia, Europe and
North Americii I visited during the period when the manuscript was
bciiig prepctrcd. Although I cannot mention everybody, I thank
them all most sinoerely. Dr A. K. Tham of the University of Singapore,
Mr J. Y. Wnltcrs of the University of Hawaii, I)r S. T. Zimmerman of

Institute kindly tillowed me to refer t20 unpublished data of their own
