rated off from the cavities in which the polypides rest, but consists 

 of prolongations of the base of the zooecia, the separating plate 

 occurring in the false stolon at some little distance from the base of 

 the pol3^pide (fig. 2). This is really what is meant by the statement 

 of several authors that in Victorella the zooecia arise from swellings 

 in a creeping stolon ; it would be more accurate to say that the 

 creeping stolon consisted of the base of the zooecia produced in 

 two or four directions. A rudiment of just such a false stolon is 

 sometimes found in Hislopia (the type of another famih' of fresh- 

 water Ctenostomes) and apparently occurs in a fully developed con- 

 dition in the Arachnidiidse. The family most closely allied to the 

 Paludicellidse is probably the Cylindroeciidse, to which Pennington 

 (in Bousfield, op. post, cit., p. 406) thought that Victorella belonged.
