In this Report the Cestodes and Nematodes collected from fishes taken off the 

 Coast of Ceylon, and especially in the Gulf of Manaar, mainly in the first half of 

 1905, are described alphabetically under their several hosts, which in their turn again 

 are arranged alphabetically. The Trematodes follow in a separate article which 

 Dr. Luhe, of the University of Konigsberg, has been good enough to write. 



Owing to the necessity of bringing to a conclusion this " Report to the Government 

 of Ceylon," the time allowed for the investigation of the large number of Cestodes in 

 the collection was very limited, and it has not, except in very few cases, been found 

 possible to "sectionize" the tape-worms. The following descriptions are based on 

 observations made on the living animals and on those that had been killed, stained, 

 and mounted. Many genera and species were represented by but two or three 

 specimens, and in some cases even one was all that was available for study. We are 

 greatly indebted to Mr. E. Wilson, of Mill Lane, Cambridge, for the care he has 

 taken in drawing many of the figures which illustrate this Paper.
