48 THAUMANTIAS SARNICA. 
and yellow. Stomach short, with proportionally large, triangular, sharp lips. Ovaries 
oblong, yellow, placed rather more than half way down the pileated sub-umbrella. Breadth 
nearly an inch. 
This pretty species was taken by Mr. Smith and myself, at Port Rush, on the north coast 
of Ireland, in June, 1839.

This is rather a large species of its division, measuring nearly an inch across the umbrella, 
which is much depressed, sub-hemispherical, smooth, colourless, and tender. The margin 
bears thirty-six (8 x4-++-4) filiform, transparent tentacles, sprmging from as many very small 
yellowish tubercles, with minute red ocelli. The sub-umbrella is elevated, as compared with 
the umbrella. It is bounded below by a rather broad veil, and divided by four radiating 
vessels ; in the second third of the length of these are seen the linear, yellow, reproductive 
glands. The stomach is quadrangular, small, and very short, campanulate, with four fim- 
briated lips. 
Taken in the Zetland seas in 1846, but not found common.

Plate XI, Fig. 4. 
E. Forbes, in Annals of Natural History, April, 1841, p. 84, pl. 1, fig. 6. 
Umbrella hemispherical, regularly convex, smooth, transparent, and colourless ; margin 
with twenty (44-+4) transparent tentacles, with colourless bases, which do not present 
conspicuous eyes. Sub-umbrella rather convex, divided by the four radiating vessels. In 
the lower half of the course of the latter, occupying nearly one half their length, are the linear 
or slightly clavate, bluish, reproductive glands. ‘The stomach is of the same hue, and is small, 
quadrangular, with four, rather large, simple, triangular lips. Breadth about half an inch, 
or rather more. 
I took this apparently distinct species between Guernsey and the Island of Herm, 
in the autumn of 1839. It is very closely allied to Zhkawmantias pileata—perhaps too 
closely. ‘ 
Plate XI, fig. 4, a and 6, represents it as seen from one side, and from above; 4, ¢, is 
the stomach and lips; 4, d, an ovary.
