Diaschiza valga, Gosse. 
[The Rotifera, vol. u. p. 77, Pl. XXII. fig. 12.1] 
This species is fairly common. I rely upon the more rounded 
and tapering form of the toes as the distinguishing feature between 
it and D. Hoodii which it so closely resembles ; the cleft down the 
back of the lorica is always apparent as it turns round a stem or 
filament. 
Habitat.—-Ponds and bogs, Co. Wexford; a pond, Co. Water- 
ford. 
Diaschiza exigua, Gosse. 
[The Rotifera, vol. ii. p. 78, Pl. XXII. fig. 13. ] 
This tiny little creature was grubbing in a small heap of flock 
and by turns exhibited all sides to me. Viewed laterally the body 
was high, the toes much decurved; viewed dorsally it was very 
narrow and much pinched in toward the foot; the head was large 
in proportion ; I could not detect an eye. Rare. 
Habitat.—A. marsh-drain, Co. Wexford. 
Diaschiza Hoodii, Gosse. 
[The Rotifera, vol. 11. p. 79, Pl. XXII. fig. 15. | 
This species is noticed as ‘‘ rare” by Mr. Gosse. I have found 
it in great abundance and of various sizes in all fresh waters ; 
not unlike Notommata lacinulata in general outline it is at once 
distinguishable by the deep cleft down the back which can be best 
seen as it creeps round the stems of small plants and alge ; the body 
is also much more depressed than that species. The margins of the 
lorica behind are most difficult to discern, as they are laid flat upon 
the body, which protrudes beyond them, thus hiding their outline. 
Habitat.—Ponds and streams, Cos. Waterford and Wexford. 
Diaschiza pzta, Gosse. 
[The Rotifera, vol. ii. p. 79, Pl. XXII. fig. 11.] 
Of frequent occurrence. The very large rose-red eye, extending 
almost wholly across the neck (when seen) denotes the species 
unmistakably. The toes, in all examples, were shorter, stouter,
