Floscularia ornata, Ehrenberg. 
[The Rotifera, vol. i. p. 50, Pl. I. fig. 9.] 
Habitat.—F requent in bogs, ponds, and deep drains, Co. Wexford. 
Floseularia cornuta, Dobie. 
[The Rotifera, vol. i. p. 51, Pl. I. fig. 7.] 
Frequent. The long tapering dorsal lobe is usually curved 
backward when the coronal cap is expanded. 
Habitat.—Ponds, bogs, and drains, Co. Wexford. 
Floseularia campanulata, Dobie. 
[The Rotifera, vol. 1. p. 52, Pl. I. fig. 1.] 
Frequent. The voracity of this species fully equals that of Floscu- 
laria ambigua. On one occasion, as I was watching the struggles 
of an unfortunate little Colurus obtusa which had been engulfed 
into the already closely packed stomach, a Diaschiza Hoodii, almost 
as large as the Floscule itself, came sailing above. Down it rushed 
headlong into the vortex; but alas! even the throat of a Floscule 
has its limits, and in spite of every effort made to swallow it, the 
prize stuck fast, head downward, heels kicking frantically above, 
until finally it was released, and went on its way rejoicing. 
Habitat.—Pond and bogs, Co. Wexford. 
Flosecularia ambigua, Hudson. 
[The Rotifera, vol. i. p. 53, Pl. I. fig. 2.] 
Frequent. The lateral lobes in every case reduced to mere 
undulations. 
Habitat.—Ponds, bogs, and drains, Cos. Wexford and Waterford. 
Floscularia algicola, Hudson. 
[The Rotifera, vol. i. p. 54, Pl. II. fig. 1.] 
I have found this tiny member of the family several times, 
attached to small clumps of Gloiotrichia growing upon the stems 
of water-plants, as described by Dr. Hudson, and also adhering to 
the leaves of other small aquatic plants, such as Calletricha, 
Lemna, &¢., but it is by no means common. 
Habitat.—Bogs and ponds, Co. Wexford; the Canal, Dublin.
