Guascotr—A List of some of the Rotifera of Ireland. 61 
Diglema revolvens, sp. nov. 
: [Pl. V. fig. 1.] 
Sp. Ch.—Body long, sunk in the middle ; head arching ; hood 
broad. 
The resemblance to D. musteda, Pl. xxx1m1. nie 4, of the “ Supple- 
ment,” cannot fail to strike the observer, but there are points of 
difference which cannot be ignored. The gastric glands, which are 
very conspicuous, are clear and round, and seated directly at the 
mouth of the large stomach, not pyriform in shape, or attached 
to it by long stalks as described of that species ; no dorsal antenna 
was visible; the trophi also differ much in shape, being broad at 
the top, the semicircular rami curving inward at the tips. The 
toes, which are always closely adpressed, are nearly three times 
as long, and the foot glands are remarkably conspicuous. I 
could see no eyes. Its manners are the very reverse of “fierce 
and active”’; it glided about with great deliberation, the head 
turned upward, now and then, and slowly revolved upon its 
long axis with protraded jaws as though in search of floating 
atoms. Length about , r o of an inch. 
Habitat.—Two specimens occurred from a stream, Co. 
Wexford. 
Diglena elnneata, Sp. Nov. 
(Pl. V. fig. 2.] 
Sp. Ch.—Body long, flat, very flexible, colour white ; head long, 
broadly truncate on frontal margin ; proboscis triangular ; foot long, 
narrow, two-jointed; toes short, straight, rod-like, slightly bent 
at the tips; no eyes. 
A very distinct species. Head thick, broad, dilated, with 
a prominent proboscis overhanging the ciliated face; trophi very 
long, the semicircular rami much projected, and always gaping; 
no eyes discernible; body long and unusually flat, of a clear 
white colour; internal organs normal; foot, two long, rounded, 
narrow joints, and two straight rod-like toes bent slightly down- 
wards at the tips; the foot glands lie within the body from 
whence their slender tubes descend to the toes. Its manners are 
peculiar; it firmly attaches the toes to the slide, stretches out 
the body to its utmost length, and thus remains for a time with
