divisions, as most of the specimens taken could thus be separated 
in the process of sorting; but the whole collection formed one 
continuous series. 
The Adult Stage.—Forbes first described the adult form from a 
few specimens which he obtained at- Dartmouth (Aug. 31, 1845), 
at Portland, and about 15 miles off the Devonshire coast. I have 
not seen any other records of the capture of this medusa. I do 
not think it is a native of our seas, but rather an occasional visitor. 
It was very abundant in 1893, but I did not see a single specimen 
during my visit to Plymouth in September 1895. Its home may 
be in the Mediterranean or in the warmer parts of the Atlantic. 
The description given by Gegenbaur of Liriantha mucronata from 
the Mediterranean corresponds very closely to the British species. 
I do not intend here to give a complete description of the adult, 
as it may be easily identified from the description and figures 
given by Forbes. It possesses the usual eight sense-organs 
(‘‘ Horbliischen”). The heart-shaped generative organs are 
nearer the margin than Forbes’s figures show them to be. Haeckel 
places great importance upon the glossoconus (“* Zungenkegel ”), 
which is the conical termination of the peduncle inside the stomach. 
He divides the genus Liriantha into two subgenera, one with and 
the other without the glossoconus. Forbes’s Liriantha is placed in 
the subgenus without the glossoconus, as Forbes never described 
it; but I have seen it in the Plymouth specimens. Unless 
specially looked for, it may be easily passed over. 
Mr. E. J. Allen, in a letter from Plymouth dated 9th January, 
1896, informs me that specimens of Lirtantha appendiculata were 
taken at Plymouth on 7th and 8th of January. It is very 
interesting to note the occurrence of this medusa in the middle of 
winter. 
NARCOMEDUS&. 
Fam. SouMARID&. 
SoLMARIS, sp. ? 
Two early stages of a medusa belonging to this genus were 
taken about three miles south of Plymouth on 7th September, 
1895. The umbrella of the largest specimen about 2 mm. in 
diameter, with 15 lappets. There is a brownish sense-organ 
(“ Horkélbchen”) in the centre of each alternate lappet. Fifteen 
tentacles, one between every two lappets. No genital ring present. 
Umbrella and tentacles colourless. The other specimen, about 
1 mm. in diameter, with 14 tentacles, 14 umbrella-lappets, seven 
sense-organs, one on each alternate lappet. The figure (pl. xx. 
fig. 7) given by Haeckel of Solmaris coronantha is very much like 
the appearance of the young medusz taken at Plymouth. 
The medusw belonging to the genus Solmaris are not natives 
of our cold seas. Most of the species inhabit the tropical seas; 
three, however, have been found in the Mediterranean, and one 
(S. coronantha) off the Canary Islands.
