Salpina spinigera, Ehrenberg. 
[The Rotifera, vol. ii. p. 84, Pl. XXII. fig. 2.] 
A few examples. ‘The lumbar spine was well-developed. 
Habitat.—A. pond, Cos. Waterford and Wexford. 
Salpina brevispina, Ehrenberg. 
[The Rotifera, vol. ii. p. 84, Pl. XXIT. fig. 4.] 
Very common. Variable in the length of the body, and also 
in the width of the dorsal cleft, which latter depends upon the 
internal condition. The stippled markings of the lorica are best 
seen in dead specimens. 
Habitat.—A. pond, Cos. Waterford and Wexford. 
Euchlanis dilatata, Hhrenberg. 
[The Rotifera, vol. ii. p. 90, Pl. XXIII. fig. 5.] 
Very common. The parallel lines of the dorsal and ventral 
flanges, and the pinched appearance of the dorsal posterior notch, 
mark the species at once. I could detect no seta on the foot. 
The large amber-coloured stomach, studded with clear globules, is 
ever rolled from side to side with rhythmical precision. 
Habitat.—Ponds and streams, Cos. Waterford and Wexford. 
Euchlanis macrura, Ehrenberg. 
[The Rotifera, vol. ii. p. 91, Pl. XXIII. fig. 6.] 
This was a very small specimen, possibly not fully grown. It 
was dying. The foot was retracted; only half of the toes were 
visible beyond the lorica. My attention was immediately arrested 
by the semicircle of very long and coarse cilia revolving at either 
side of the head, just at the juncture of the lorica. ‘The body was 
- more depressed than than that of Z. dilatata, the lorica not pinched 
in, above the foot, but the flanges were almost identical in shape 
with that species. 
A. single specimen among the branchlets of Vaucheria. 
Habitat.—A. stream, Co. Carlow.
