the body, the very transparent lorica, and the rose-pink hue of the 
large eye; the very conspicuous trophi are of an orange brown 
colour, slightly tinted with pink from their close proximity to 
the eye. 
Habitat.—Bogs, drains, streams, Cos. Waterford and Wexford. 
Distyla flexilis, Gosse.

This species abounded amongst Conferve growing on the 
sides of a water-tub placed under a pump in the month of Sep- 
tember. Earlier in the summer not a single specimen occurred 
from the same place. The longitudinal flutings of the very flexible 
lorica were strongly marked ; the eye was conspicuous. Its manners 
were always slow, creeping lazily among the filaments. 
Habitat.— Among Conferve in a water-tub, Co. Waterford; a 
bog, Co. Wexford. 
Monostyla lunaris, Ehrenberg. 
[The Rotifera, vol. ii. p. 98, Pl. XXV. fig. 2.] 
Very common. | 
Habitat.—In all waters, Cos. Waterford, Carlow, Wexford, 
and Kerry. 
Monostyla cornuta, Ehrenberg. 
[The Rotifera, vol. ii. p. 98, Pl. XXV. fig. 1.] 
Common. Cos. Wexford, and Waterford. 
Monostyla Lordii, Gosse. 
[The Rotifera, vol. 11. p. 99, Pl. XXYV. fig. 5. | 
This is a fairly common species. ‘The coarse tesselation and 
crumpled appearance of the lorica affords a satisfactory dis- 
tinction from its congeners, but invariably the square excavation 
behind was lacking, a rounded outline taking its place. This 
variation of form is noticed by Mr. Gosse, who suggests that it 
may afford sufficient ground for specific rank. 
Habitat.—Ponds and bogs, Co. Wexford; Vaucheria, from a 
stream, Co. Carlow.
