unknown, it differs in having emarginate zooecia with a w^ell-defined 

 furrowed keel and in not being thickh' encrusted with compara- 

 tivel}' large sand grains. 



At Shasthancottali the zoarium was found entangled with that 

 of a delicate form of Plumatella fruticosa which closely resembled 

 it externally. With a little care, however, it was found possible 

 to disentangle the two species. The point is important as tending 

 to explain Jullien's' belief that Fredericella is merely an abnormal 

 form of PIuDiaiclla. and in this connection I may state that in 

 Scotland I have found a statoblast of Plumatella adhering to and 

 partiall}^ embedded in the ectocyst of Fredericella. 



Fredericella has not hitherto been recorded from the Oriental 

 Region, although F. sultana is said to occur in Australia as well as 

 in Europe and North America.
