ing together of individuals to form a resting state, to the pro- 
duction of a similar state, developed in a more complicated 
fashion and raised upon a highly differentiated stalk, through 
intervening forms, in which this stalk appears merely as a 
supporting base. 
The most essential discrepancy which is apparent in such 
a comparison rests on the fundamental difference in cell 
_ structure already referred to, since although the Acrasiez have 
_ taken a decided step away from the true Myxomycetes in the 
| production of cells which neither coalesce nor produce pseudo- 
podia (as in the Guttulinacee), the step from such amece- 
boid cells to definite rods having all the characteristics of 
typical schizomycetous cells is, to say the least, a very long 
one. This fundamental difference necessarily involves equally 
_ important differences connected with the modification of in- 
dividuals, in either case, while in the resting state, even when 
adefinite spore formation takes place in both instances; while 
the encystment of numerous individuals to form a spore-like 
_ body, in the manner above described, presents an additional 
_ point of deviation in this connection. 
In view of such important differences, the writer would 
hesitate to assume even a remote genetic connection between 
@ two groups on a basis of resemblance which might well 
be purely accidental. Yet it is a question to which further 
investigation in this direction may afford a more definite an- 
to be, however, the:
