196 SPOLIA ZEYLANICA. 
(ec) Seven specimens of Dipylidium caninum, L., from a dog. 
Average length of worm, 85 mm. 
Length of largest segment, 6 mm. 
Breadth of largest segment, 3 mm. 
Total number of segments, 22. 
(f) One specimen of Ascaris lumbricoides, Linn., from man. The 
specimen was a female of a grayish-brown colour. 
Length 230 cm., greatest breadth 7 mm. 
In addition to the foregoing, there were several fragments of a 
Cestode of the genus 7’enia, said to have been obtained from a rat. 
No heads were present, and it was found impossible to identify the 
fragments further. 
It will be obvious from the foregoing that our knowledge of the 
Cestodes found in the common Ceylon animals is very limited.
