number of observers, yet no mention can be found of filaments 

 or pellets l^eing formed by it. Had such an observation been 

 recorded the chief specific character would disappear. il/. 

 fimhriata undoubtedly uses the ciliated cup to form filaments. 

 It is, of course, possible that the European form may be found 

 to possess this power, but until this is done it appears best to 

 retain the form as a true species.

The original description of this form contains the statement 

 that it is " found in small colonies."' 



It has since been found in clusters of quite remarkable size 

 lying on the surface of the mud in a sliallow pool in lobose 

 masses upwards of an inch in diameter. These large colonies 

 are masses of adherent dense, gelatinous tubes, and are due to 

 that habit of the young, unlike those of L. striolata and L. 

 pednnrulata, of joining the colony from whence they are
