Definition. —Glugeide possessing a myxosporidium, and in which the 
pansporoblast produces an inconstant but large number (always more 
than 8) of spores; pansporoblast membrane not subpersistent; type, 
G. microspora Thél. (synonym for anomala Moniez).

Myzxosporidium.—Kctoplasm and endoplasm recognizable. 
Spore formation.—Pansporoblast membrane thin, disappearing soon 
after spore formation. Sporoblasts, consisting of small globules with 
clear nuclei, sometimes disposed in very great numbers, sometimes iso- 
lated in groups of 4, 10, or 12 within the pansporoblast membrane. 
Spore.—A little smaller than the similar parasite of Cottus scorpio, 
2-5 to 3 wlong; 1 told «broad; characters otherwise identical (Thé- 
lohan, 1891). Length, 3 to 3°5 uw; breadth, 2 4 (Thélohan, 1892, p. 174). 
Capsule present (Henneguy & Thélohan, p. 619). 
Habitat.—Upon section of the muscles affected, the parasite is seen 
to have its seat in the interior of even the primitive fibrille of the 
muscles of Callionymus lyra. Not encysted, but forming a parasitic 
mass, destitute of an envelope, in which ripe spores are seen with 
others in course of development. 
Effects —Unlike the otherwise very similar condition in Cottus scorpio, 
the muscular fibers soon break up and undergo vitreous degeneration,
