80 REPORT OF NATIONAL MUSEUM, 1921. 



possible number of duplicates which the rest of the series might 

 yield when eventually worked up. With the receipt this year of 

 approximately 100.000 specimens of Philippine fishes this method 

 of arriving at a fair estimate of the number of duplicates available 

 for distribution proved utterly inadequate. It has therefore been 

 considered the better plan only to list the number of duplicates 

 actually segregated. It may be further noted that the figures for the 

 division of plants are exclusive of the lower cryptogams. In the 

 following table the figures in parentheses indicate the number of 

 duplicates included in the total :
