 1958, respectively. The techniques used on YC03 were employed. The station 

 numbers are tho&e u^ed by the original investigators except that an initial 

 letter was dropped, but in YOOl , 201 is used for one station merely labeled

 which an ''E" was dropped.

 a discussion of the data. The pigment values were from cells caught on filter 

 paper and measured by Hogetsu and Ichimurii's (1954) phaeophytin method. 

 Artificial station numbers were used.
