Guiascorr—A List of some of the Rotifera of Ireland. 47 
with light from above. ‘The foot and toes were exactly as described 
by Mr. Gosse. <A pair of moderate-sized auricles were frequently 
everted. 
Habitat.—A single example from a marsh drain, Co. Wexford. 
Notommata lacinulata, Ehrenberg. 
[The Rotifera, vol. ii. p. 26, Pl. XVII. fig. 9. ] 
Common everywhere. 
Notommata volitams, sp. nov. 
[Pl. III. fig. 4.] 
Sp. Ch.—Body cylindric, tapering to the foot; head very 
broad; auricles small, and continually everted; brain clear; toes. 
rather long. 
So like WV. Jacinulata in size, general appearance, and manner, 
gaily flitting about with auricles everted and protruded trophi, it 
was not until sometime that I recognized its pretension to specific 
rank. The body tapers abruptly both in width and depth from 
the very broad head to the tail. The single-jointed foot bears 
two decurved blade-shaped toes, just double the length of the above- 
named species. 
Abundant. 
Habitat.—Ponds and streams, Cos. Wexford and Waterford. 
Notommata cylindriformis, sp. nov. 
[Pl. IIT. fig. 5.] 
Sp. Oh.—Body cylindric, long, with parallel sides; brain 
large, dark, and sacculated ; toes of moderate length; auricles not 
observed. 
Occurred several times. The dense black brain mass is some- 
what similar to that of VV. aurita, and placed very low down in the 
neck ; but no eye was apparent. The body, always white through-. 
out, is of a narrow oblong shape, internal structure normal, length 
about 74,th of an inch. 
Habitat.—Ponds, streams, Co. Wexford.
