Giascorr—A List of some of the Rotifera of Ireland. 53 
Furcularia cea, Gosse. 
[The Rotifera, vol. ii. p. 42, Pl. XX. fig. 4.] 
A single example; characteristics not very satisfactory. 
_ Habitat.—A. stream, Co. Wexford. 
Furcularia gibba, Ehrenberg. 
[The Rotifera, vol. i. p. 43, Pl. XIX. fig. 13.] 
Although bearing considerable resemblance to Diaschiza semi- 
aperta, with which it is said to be often confounded, the distinctions 
are sufficiently obvious. The gibbous area of the body presents 
none of the angularities of outline noticeable in the latter species. 
The foes also are much shorter, of a stouter make, and their upward 
curve is more gradual. ‘The eye is situated almost on the frontal 
margin. ‘The trophi are larger and more unsymmetric. 
Habitat.—Streams and ponds, Cos. Wexford and Carlow; not 
unfrequent in Co. Waterford; the Canal, Dublin. 
Furecularia ensifera, Gosse. 
[The Rotifera, vol. 11. p. 48, Pl. XX. fig. 3.] 
The peculiar manner in which the toes are articulated appa- 
rently to the trunk, without the intervention of a foot, affords a 
good feature for recognising the species. I have seen the rounded, 
pliant, flesh-like toes lapped round each other at the tips in a sort 
of twist. 
Not uncommon. 
Habitat.—Streams, bogs, ponds, Cos. Carlow, Kerry, Waterford, 
and Wexford. 
Fureularia marina, Dujardin. 
[The Rotifera, vol. ii. p. 44, Pl. XIX. fig. 15. ] 
Common in tide-pools. 
Habitat.—River Barrow, Co. Wexford. 
Fureularia Boltoni, Gosse. 
[The Rotifera, vol. ii. p. 45, Pl. XX. fig. 2.] 
I was fortunate enough to find what I take to be this species 
in great abundance in a stream running by the “The Mill Post,” 
Co. Waterford. It was, indeed, quite the specialty of the stream: 
It is recognisable at once by the peculiar formation of the foot, of
