definite type, but to three distinct independent types, as found in Zanclea, Ctenaria, 
and Cladonema respectively. 
Genus EveuTHERIA, de Quatrefages, 1842. 
This genus is better known to English zoologists by the name of Clavatella, 
through Hincks’s description of Clavatella prolifera, which had, however, been 
previously described by de Quatrefages under the name of Eleutheria dichotoma. The 
Medusa has normally six tentacles, each of which is bifurcated. The upper or outer 
branch of the bifurcation terminates with a large cluster of nematocysts, and the lower 
branch ends with an adhesive dise or sucker, by means of which the Medusa is able to 
crawl about sea-weeds at the bottom of rock-pools. 
A second European species is recorded under the name of Eleutheria claparedii. 
It differs from E. dichotoma in having both branches of the tentacles terminating with 
clusters of nematocysts. It is quite probable that it is only an abnormal form of 
E.. dichotoma, with some nematocysts in the adhesive discs. 
Another species of this genus inhabits Stanley Harbour, Falkland Islands. A 
single specimen was found there by Mr. Rupert Vallentin in 1898, and I described it 
under the name of Eleutheria vallentini. In 1900 Mr. Vallentin obtained some more 
specimens which have not yet been described. This species has twenty-four tentacles, 
each of which is bifurcated. The upper branch bears a terminal cluster of nematocysts, 
and, in addition, two to three clusters along the upper side, and occasionally a cluster 
on the lower side. The other branch of the bifurcation has an adhesive disc. The 
finding of an E/eutheria in the Falklands was of considerable interest, because the 
genus had been previously known only to Europe. 
In 1908 Prof. Bedot published a Paper bearing the title “Sur un Animal Péla- 
gique de la Région antarctique,” and the animal was named Wandelia charcoti. It 
was taken off Wandel Island, lat. 65° 8., long. 66° W. (Paris), by the ‘ Francais’ 
Expedition. The specimens, as the figures show, were in a very fragmentary 
condition. Although Prof. Bedot felt sure that the animal was not the remains of a 
Siphonophore, he was uncertain about its position amongst the Coelentera. 
At first I did not recognisé the animal, but on a second reading a picture of an 
Eleutheria came into my mind. As there was nothing in the description or figures 
to render the idea an impossible one, I wrote to Prof. Bedot. I suggested that 
his remarkable animal might possibly be an E/eutheria, and sent him the original 
drawings of Eleutheria vallentini for comparison. Prof. Bedot most kindly sent 
me specimens of Wandelia for examination, and I, in return, sent specimens of 
Eleutheria hodgsoni. We both came definitely to the conclusion that Wandelia was 
undoubtedly an Eleutheria. 
The condition of the specimens of Wandelia was so bad that without a good 
clue it was practically impossible to associate the animal with an Eleutheria. I was
