ASCHELMINTHES 



This phylum is taken as including the Rotatoria, Gastro- 

 tricha, and Echinodera, with due recognition of the fact that 

 these groups are not as closely related as might be desired 

 when combining them into a single phylum. Only the last- 

 named group is represented in the Survey results. 



KINORHYNCHA 

 Class ECHINODERA 

 The collections of the Survey comprise but three species, 

 which were all described as new by Blake (1930). These arc 

 the only species known from the Western Hemisphere.
