Ceelopus brachyurus, Gosse. 
[The Rotifera, vol. ii. p. 69, Pl. XX. fig. 21.] 
This species is noticed as “rare.” I have found it in abun- 
dance amongst the leaves of Lemna trisulca and other small plants, 
in bogs, drains, and ponds. The very short, plump body, the 
absence of spinous projections towards the head, and the uninter- 
rupted curving line from the neck to the tip of the strongly- 
decurved toes defines the species well. 
Habitat.—Bogs and drains, Co. Wexford ; a marsh drain, 
Tramore, Co. Waterford. 
Celopus eavia, Gosse. 
[The Rotifera, vol. ii. p. 69, Pl. XX. fig. 22.] 
The short glimpse I had of this queer little creature did not 
give me an opportunity of naming it with decision, but the gibbous 
development behind and the position of the toes, which were placed. 
far inward on the ventral surface, lead me to believe that I have 
named it correctly. 
Habitat.—A. stream, Co. Waterford. 
Celopus minutus, Gosse. 
[The Rotifera, vol. ii. p. 70, Pl. XX. fig. 20.] 
This hump-back species was floating about quite dead, and 
stretched out toitsfull length. I could not detect the slender tubes 
from the head to the stomach mentioned by Mr. Gosse, but mstead 
a tangle of shapeless rods just above it, presumably the trophi 
collapsed by approaching decay ; the toes, two broad decurved 
blades ewactly alike in size, seemed to spring from the same point 
just inside the lorica. They were stretched out in a line with the 
body, the points diverging so as to form a moderate angle. 
Habitat.—A stream, Co. Wexiord. 
‘Dinocharis pocillum, Ehrenberg. 
{The Rotifera, vol. ii. p. 71, Pl. XI. fig. 1.] 
Not uncommon. The long-spurred variety predominates. 
Habitat.—Pond and bogs, Cos* Waterford and Wexford.
