_ yellow tint, this being, of course, dependent upon the nature of the 
food. The shape of the body, foot, and toes, were all identical 
with the figure in the Monograph, and its manners completed the 
picture. After many rapid flights, twists, and turns, it at length 
dashed into some flock adhering to a stem, contracted its body into 
a ball, and kicked itself roundand round with great vigour, until 
weary of watching I dislodged it. A few other examples occurred 
from different localities, but it is a rare species. 
Habitat—Streams, Co. Wexford; a bog, Co. Waterford; the 
Canal, Dublin. 
Notommata cyrtopus, Gosse. 
[The Rotifera, vol. ii. p. 22, Pl. XVII. fig. 7. ] 
Not frequent. The two colourless eyes always apparent. In 
several examples the auricles, of somewhat oblong shape, were 
freely everted. 
Habitat.—Streams, amongst alge, Cos. Wexford and Carlow. 
N.B.—Hitherto the auricles of this species have not been seen, 
but I fancy their presence was suspected. 
Notommata tripus, EKhrenberg. 
[The Rotifera, vol. ii. p. 22, Pl. XVII. fig. 4.] 
Although the auricles of this species are somewhat larger and 
more rounded than represented in the figure in the Monograph, 
they never could be termed “great globose,” as described of WV. 
pilarius, and the general contour of the body, together with the 
thick and deeply incised folds at the neck, approach closely to it. 
It is a quaint little creature, whose upright tail gives it a marked 
individuality, and a fairly common species, which seems to take 
the place in this country of its congener JV. pilarius, which I have 
not yet seen. I found one specimen whose brain (?) or eyeball (?) 
had evidently received some injury, for it hung from the back of 
the red eye as a grey pear-shaped globe, suspended by the stalk, 
which wobbled about from side to side when the animal moved. 
The digestive sac seems simple and undivided; I have seen a 
rotation of granules throughout the entire chamber. 
Habitat.—Pond, bogs, and streams, Co. Wexford.
