of the Medusa which has received the name of Callirhoe Basteriana. Plate xev, figs.

Forskalina, all copied from Forskal.

standard paper. Unfortunately the plates and figures referred to in this valuable memoir 
have never been made public, so that it is beyond the power of the British naturalist to 
determine the species mentioned as inhabitants of the Channel, for the descriptions are 
too often insufficient. The following genera of naked-eyed Medusz, are characterised 
for the first time in this paper: Eudora, Berenix, Orythia, Favonia, Lymnorea, Geryonia, 
Carybdea, Phorcynia, Eulimenes, Aiquorea, Foveolia, Pegasia (?), Callirhoe, Oceania, 
Aglaura, Melicerta (?), Euryale. The names of the species will be found in the table 
which I have constructed from Lesson, further on. An issue of the original plates would 
be a great boon to science, as few naturalists have had such opportunities of observing the 
Medusee in all parts of the world.

Several Medusie are represented in the plates to this paper. Of these, one, the Geryonia 
tetraphylla, is a naked-eyed form, allied to our G. appendiculata, and resembling it 
in having eight tentacles alternately differing in size. Their structure is not given. The 
extremity of the peduncle is represented as having a round orifice, which is a mistake, as 
in the description, the peduncle is said to be “bipollicaris, cylindricus, flexilis, apice 
(ore) truncato dilatato guadrivalvato membranaceo, maculis quatuor viridibus notato.” 
It inhabits the Indian Ocean. (Loe. cit., t. xxvii, f. 2.) 
The “ Medusa campanulata’ of this paper (pl. xxx, f. 1) seems to me to be a mutilated

animal, doubtfully of this division, and the M. mucilaginosa is possibly a mutilated 
Polyxenia. Both are from the Pacific Ocean, and the imperfection of the drawings is due 
to the specimens, and not to the describers, as they expressly state their doubts respecting 
the generic affinities of both forms, and suggest the necessity of fresh observations.

that the authors did not very clearly comprehend what they saw.
