adhering in a cluster to the side of the glass. They did not leave her 
body until the hour of her death : they have increased very little in size 
in the last four months.” 
E. vulgaris, Johnst. 
Four individuals of this species found among subaquatic plants at Lough 
Neagh on the occasion already alluded to were brought home for examina- 
tion. They were not more than half the size of those figured by M.- 
Tandon, nor of so dark a hue generally — anteriorly they were somewhat 
hyaline. They each possessed eight eyes, which changed their places like 
objects in a kaleidoscope ; their usual position was, the four anterior in a 
straight line across the body, and so they always appeared when s N 
the anterior portion of the body was pressed against the phial r’**l 
in the act of progression : the hinder pairs of eyes generally ap- ["••j 
peared as here represented, or across the body, but occasionally displayed 
themselves in the opposite direction thus, and the anterior eyes 
were then seen as figured, the head of the creature at the same 
time having quite a truncated aspect. Of several species of 
“ Hirudinees ” brought from L. Neagh and kept alive for a few weeks, 
this was the only one that exhibited the power of swimming ; it was ex- 
tremely active, and wriggled about through the water like an Ammoccetes 
— it was truly “ as merry as a grig.” 
August 20, 1846. — Among the Hydra, &c. alluded to under Planaria 
nigra as brought from the Phoenix Park, Dublin, was an individual of 
this species the water from which it was taken for examination to-day 
had been kept unchanged for three months in a large glass globe.

Specific Character. — “ Body oval ; anterior portion not dilated into a 
distinctly-formed head ; back smooth ; ” margin slightly crenulate ; eyes 
eight ; stomachal lobes eight, subpinnate ; prevailing hue hyaline. 
The size commonly extends to 9 lines. The eight eyes are disposed in 
four pairs, each pair on the same segment of the body, the two hinder 
pairs the larger ; eight pair stomachal lobes anterior to great stomachal 
pouches, subpinnate — as much so as represented in G. marginata, Moquin- 
Tandon, pi. 14, f. 14, 2nd edit. — the two anterior pair are small, and when 
empty but little apparent ; from each side of the stomachal lobes emanate 
four subpinnate branches which appear in a continuous row with the 
stomachal lobes anterior to the pouches on each side. It may be re- 
marked that the spur-like form of the stomachal pouches (see pi. 13, fig. 
6 c & d, Moquin, 2nd edit.) was not always clearly defined, in which
