corresponds with the characteristic features of the genus Laodice 
in possessing filiform and club-shaped cirri between the tentacles, 
and in the absence of marginal vesicles. 
The other species of the genus Laodice (L. mediterranea, 
Gegenbaur, LZ. calcarata, Agassiz, and L. ulothria, Haeckel) appear 
to differ so slightly from one another, that I am inclined to regard 
them as one species. 
The species which have been vaguely described by the early 
naturalists had better remain provisionally under the name of 
Laodice cruciata (Forskil). I think for the present, until more is 
known about the genus, that Thaumantias mediterranea had better 
be regarded as a distinct species—Laodice mediterranea (Gegen- 
baur),—and Cosmetira punctata as a synonym of it. 
I do not intend publishing a description of the Valencia Laodice 
until I have collected more specimens, which may then throw 
some light upon the other species. 
Fam. EUCOPID2.

Thaumantias pilosella, Forbes (1848); Gosse (1853). 
Laodice pilosella, Agassiz (1862). 
Laodice stauroglypha, Agassiz (1862). 
Laodice cruciata, Garstang (1894). 
Forbes has given a fairly complete description of this species, 
omitting only the marginal vesicles. These important organs 
were apparently not considered by Forbes of any importance in 
the specific description of a medusa. Gosse found this medusa 
very abundant at Ilfracombe, and described it again under the 
name T'haumantias pilosella, with eight marginal vesicles. 
At Valencia, during April and May, I found four specimens of 
a medusa which is identical with the Thawmantias pilosella of 
Forbes and Gosse. 
Forbes in his description of the species states :—“ The umbrella, 
which sometimes measures nearly two inches in diameter, but 
more usually one, or one and a quarter, is hemispheric, and 
shaped like a watch-glass, but much more convex. It is trans- 
parent and smooth, except on the sides towards the margin, where 
it is as if woolly, being invested with minute epidermic hairs 
composed of fibrous cells. These, though sufficiently conspicuous, 
may escape the observer who is not aware of their presence, in 
consequence of their transparency. 
“The margin is fringed by very numerous (100) extensile (but 
usually borne rather short), pale pinkish tentacula, with bulbous 
bases. The bulbs are ocellated, with dense crescentic masses of 
purple pigment-cells. When the margin is much magnified, it is 
seen to be bordered by a narrow band or thread of fibrous cells, 
from which the tentacles spring, and between each pair there are 
six or seven short, fine, secondary tentacles, without ocelli at their 
bases... . The sub-umbrella is depressed, and on its surface run the
