Prof. Allman on the Hydroida. 63 
followed Agassiz in restoring to this remarkable hydroid the name 
of Candelabrum, proposed for it by De Blainville. More mature 
consideration, however, has induced me to return to the name of 
Myriothela. De Blainville found that a species of this genus was 
described by Fabricius under the name of Lucernaria phrygia, 
and it was plain to him, as it would have been to any zoologist 
of that day, that Fabricius’s hydroid was no Lucernaria ; hence 
his proposal of a new generic name for it. 
The laws of priority, if rigidly enforced, would certainly justify 
the suppression of Sars’s name in favour of De Blainville’s ; but 
it is evident that De Blainville was utterly ignorant of the ani- 
mal for which he proposes the generic name of Candelabrum: 
he asserts that it “certaimement n’appartient pas au type des 
Actinozoaires,” and he concludes his allusion to it by affirming 
its affinity with Sipunculus. 
Under these circumstances I cannot but agree with my friend 
Mr. Alder in feeling that De Blainville’s name has no claim to 
take the place of Myriothela, given to this hydroid by the emi- 
nent Norwegian zoologist, who was well acquainted with it, and 
to whom we are indebted for the first legitimate zoological de- 
scription of it. 
I have never had the good fortune to meet with a specimen 
of Myriothela ; but I now learn from Mr. Alder (to whom I am 
indebted for drawings of the M. arctica, in its young and adult 
states), that the young leave the adelocodonic gonophores of 
this hydroid in a condition which closely resembles the free 
state of Tubularia; and he further suggests the probability of a 
close affinity between Myriothela and Acaulis. With this view, 
which would place Myriothela in the family of the Tubularide 
rather than in that of the Corynide, I am well inclined to agree.

The Medusa of Zanclea implexa, Alder. 
Some years ago I described the remarkable medusa of the 
Zanclea (Coryne) implexa of Alder, to whose singular peduncu- 
lated capsules, filled with thread-cells, and set along the whole 
length of the marginal tentacles, I called special attention *. 
At the end of April last I dredged, off the Forfarshire coast, a 
colony of the Zanclea, which, after remaining for about a fort- 
night in a jar of sea-water, threw off its medusz. On examin- 
* Notes on the Hydroid Zoophytes, in Ann. Nat. Hist. for July 1859, 
p- 54. The hydroid is there named Coryne Briareus ; I, however, agree 
with Mr. Alder and Dr. T. 8. Wright in referring it to the previously 
described C. implexa of Alder, a hydroid which I further think must be 
now referred to the genus Zanclea of Gegenbaur. (See the Synopsis 
of Tubularian Hydroids, p. 357.)
