COPEPODS FROM LAKE ERH HAI, CHINA 



By Sidney C. Hsiao 



During the years 1943-i5 a limnological survey was made of the 

 fresh-water lake Erh Hai (the Tali Lake) in Yunnan, southwest 

 China. An examination of the copepods from the plankton hauls 

 showed a number of new species of Eucopepoda and a large number 

 of individuals of one species of Branchiura. It is the purpose of this 

 paper to record these forms. The limnological data that accompanied 

 the specimens have been reported elsewhere (Hsiao, 1946 and 1949), 



Grateful acknowledgment is made to Prof. G. E. Hutchinson for 

 putting at our disposal specimens collected during the Yale North 

 India Expedition and for his kind advice and encouragement. The 

 present work was done during the tenure of a Seessel Memorial 

 Fellowship in the Osborn Zoological Laboratory of Yale University ; 

 the use of the facilities of that laboratory are also gratefully 

 acknowledged.
