hanging downwards into the beil cavity. The muscular tissue is 
weak. A great number of short tentacles (about 160). I have not 
been able to find the sense organs. — Velum is comparatively broad, 
but thin and with weak muscles; 
the velum is whole only in the 
best preserved specimen, in the 
other specimens it is torn or 
quite lost. — The colour is deep 
reddish brown. The distal part 
of the manubrium is in all the 
specimens white with four red 
edges; the lips are red. 
This pretty medusa, of which 
6 specimens are to hånd from deep water, belongs undoubtedly to 
the genus Aglantha. It reminds one of Maas’s “ Melicertum ’ pro- 
boscifer (Maas 1897). It differs from this tropical Pacific species, 
in that it lacks a well developed stomachal peduncle, that there 
are only 4 lips, and that the gonads are fastened closely by the 
manubrium (see fig. 2). In the Pacific species the gonads arise 
from the middle of the radial canals. 
It is certain that the two forms are closely related and I have 
no doubt, that both of thern have to be referred to the genus 
Aglantha.
