Two New Species of Chaelixjastt 



9: 



C. vicforiensis appears very different. It reseinhU's C pelhtcidus 

 and C. punjahensis, etc., in secondary fission. It i.s niucli larger 

 tlian C punjahensis, and a little larger than C. pellncidus, being 

 nearest C. hcngalensis in this respect. 



A very marked feature in C. vicforiensis. is the fact that the 

 anterior portion of the nervous system is completely double (this is 

 clearly seen by reference to Fig. iii.). while in C. ausfralis only 

 the cord itself is double. 



In C. victoriensis I could not see any of tlic dor.sal papillae and 

 hairs as in C. australis. Both C. australis and C. victoriensis 

 resemble C. fliformis in the absence of the dilatations of the- 

 oesophagus. 



I should now like to thank Professor Spencer and Di'. Hall, under 

 whom this work has been undertaken, for all their help and advice.
