confusion, but since I have seen specimens from Plymouth 
and Jersey which have all the distinguishing characters 
of the Haliclystus auricula described by Clark in his 
Prodromus (12) and again with great detail in a fully illus- 
trated monograph in the Smithsonian Contributions, 1878, 
(14) I prefer to follow Clark in identifying his species 
with the European Lucernaria auricula, Rathke (2). 
Haeckel on the other hand considers it probable that 
Haliclystus awricula, Clark, is confined to the Ameri- 
can side of the Atlantic, and identifies ZL. auricula, 
Rathke, with 4. octoradiata, Lamk., which is described as 
a second Huaropean species by Clark. Rathke’s figures 
as far as they go support Clark’s view. 
It may be noted further that Lucernaria auricula, 
Rathke, was confused by a number of the earlier writers 
with L. auricula, Fabricius (1), one of the Cleistocarpidee 
[Manania auricula (Kab.) Clark, Halicyathus lagena 
(Miller) Haeckel] . 
Haliclystus, sp. 
The third species of Lucernarian found at Port Erin 
differs materially from any species previously described as 
far as [know. The members of this family seem parti- 
cularly liable to abnormalities affecting more especially 
the number and arrangement of the tentacles, as noticed 
under Depastrum, and I am loth to establish a new species 
on the scanty material at present available. After some 
consideration, I refer this species provisionally to the genus 
Haliclystus, for though it presents considerable divergence 
from the 3 species of that genus which have been already 
described, yet its structure, so far as I have been able to 
make it out, is in accordance with the generic definition 
both of Clark and Haeckel except as regards one point 
which is not I think of very great importance. 
Three examples of this form were found last year;
