half of the brain rests upon an enormous mastax, the square forci- 
pate trophi reaching close to the disc. The body is of oblong shape 
slightly swollen in the middle and deeply fluted longitudinally, 
the circular stomach is situated very low down. ‘The great 
transparency of the tissues rendered all other organsinvisible. The 
foot one long and simple joint, the toes two pointed cones, not 
quite halfits length. Its manners were quiet, gentle, and deliberate 
when feeding, and it swam in the open with an easy gliding motion. 
I saw no auricles. Length about ,);th of an inch.

Diglena grandis, Ehrenberg.

A. splendid specimen amongst the branches of Cladophora from 
a stream. It was seated toes apart, and fell about awkwardly from 
side to side as though in a dying state. The contents of the 
stomach were of a yellow colour. The head was constantly in- 
verted. The resemblance to the figure in all points was unmis- 
takable. 
I found one also among alge from a stream in the Co. Water- 
ford, in whose body I was surprised to see the gleam of many bright 
red eyes, but the mystery was almost immediately explained by 
the birth of three fully formed individuals in uninterrupted suc- 
cession ; the first and largest measuring 5}, inch in length, includ- 
ing the toes. After the event the parent, much reduced in girth, 
swam carelessly away; the babes, I regret to say, drifted under 
some vegetation, and when trying to bring them into better view 
I must have killed them by over pressure of the cover glass, for 
they showed no signs of life.
