representing, one pansporoblast, and either still sur- 
rounded by a hypertrophied host-cell, or else free, but only 
owing to the latter’s break-down. ‘Such an origin and 
nature of the daughter-individuals would obviate any 
necessity for Doflein’s hypothetical “ swarm-spores,” the 
occurrence of which would be without analogy in the 
Sporozoa. 
The spores themselves are seen in fig. 7 (a) and (6). 
They are oblong-ovate in shape, and average 3u by 15— 
13u in size. They are the same in the two cases, those 
drawn in (a) coming from specimen A, and those in (6) 
from B. Glugea spores are usually pear-shaped, but, after 
very careful examination, I cannot, with certainty, dis- 
tinguish any difference in this respect between the two 
ends of those of G. stephani. Linton (Le.) also says 
nothing about the spores from his specimen being pear- 
shaped. Not having had any fresh material to work 
with, I have been unable to observe the expulsion of the 
polar filament in this species, but in fig. 7 (¢) are seen a 
few fresh spores of G. anomala from a stickleback, one 
of which shews the filament extruded. The clearer space 
at the opposite end (which is nearly always evident in 
fresh Glugea spores) represents a vacuole—also generally 
apparent in the stamed spores of G. stephani. In-one or 
two instances [ saw a faint longitudinal suture (s) marking 
the junction of the two valves of the spore. The contents 
are most difficult to interpret correctly, sice, owing to the 
absence of a pear-shaped end, one cannot say positively 
where the polar-capsule is situated. There are usually 
two unstained clear areas, with the sporoplasm (2.e., 
the germ) lying between. One of these is well 
marked, and invariably contains a small, rounded, 
deeply-staining granule; whilst the other seems to vary 
in size, and is not always very obvious. The former is,
