and South America ; very probably, however, itis generally diffused in 
fresh water ; perhaps also it is confounded with Aphanochete repens, 
which Nordstedt specifies for the Sandwich Islands and New Zealand.”

Professor Moebius gives the following note :—‘ This form, which is 
distinguished by the fact that the thallus usually only consists of two 
eells, was found upon Hormiscia subtilis (Fig.14). Both the cells are 
pointed at the end, so that the thallus appears spindle-shaped from 
above. Generally each of the two cells, but sometimes only one, 
carries a hair; longer pieces of filament were only exceptionally seen 
amongst the 2-celled portions, r are usually placed 
together in groups, so that the Hormiscia thread is covered with them
