Nebela collaris (Ehren) Leidy.— -In nearly ever}' drop of 
sphagnum water examined, at least one specimen of this 
species was observed. A slight neck was constantly present, 
and the margin of the mouth was dentate, crenuiate, irregular 
or entire. 
Quadrulella symmetrica (Wailich) Cock. — I have followed 
Cockerill, who records this genus as Quadrulella, instead of 
Quadrula, which is pre-occupied in the Mollusca. I observed 
one specimen in the stagnant water. This is unusual, and 
the only other Queensland locality where I have obtained 
stagnant water in which it occurred, is the Springbrook 
Plateau. In all the specimens examined, a distinct neck was 
present, approximately equal to half the length of the test. 
Order Filosa. 
Corythion duhium, Taranek. — Not uncommon, but only 
one damaged specimen was met with in the stagnant 
water. 
Euglypha cristata, Leidy. — This rhizopod occurred not 
uncommonly in material I obtained from Bribie Is. in 1915. 
Up to the present I have observed only one specimen in the 
Stradbroke Is. gatherings. 
Euglypha tuber culata, Dn]. — Wailes in “British Fresh- 
water Rliizopoda and Helizoa,” Vol. III., believes that the 
form described and figured by Leidy under the name 
Euglypha alveolata, Duj., consists of two distinct species, to 
which he has applied the names Euglypha tuherculata, Duj., 
and Eviglypha acanthophora, Per, the former including the 
unspined forms, and the latter the spined. As al* the alveolata 
type were unspined, I have called them Euglypha tubercukita , 
Duj. 
Hyalosphenia platystoma, West. — One small Hyalosphenia 
was seen, which appeared to be identical with the form 
described and figured by West (Journ. Linn. Soc. 1903), as 
Hyalosphenia platystoma, West. 
Sphenoderia dentata, Pen. — Only one specimen was 
observed, and it was found in the stagnant water material. 
There was a number of scales inside the animal, similar to 
those which occur in Euglypha. 
Placocysta sp. — An unidentified specimen was observed, 
which appeared to be a Placocysta, as the test was typical, 
and the mouth entire. Instead of being spined in the manner 
characteristic of Placocysta spinosa, Leidy, it had only three 
or four spines arranged around the fundus, like those of 
Euglypha acanthophora, Per,
