Gives a list of nine species of stony corals and four of Alcy- 
onaria. Doubtless a little closer examination of the Bermuda 
reefs would yield a much larger number of species.

In our special part will be found an analysis of the genera 
given in this first part of Professor Kolliker's memoir, and a list 
of the new species. It is impossible within our limits to give 
an epitome of the details of the anatomy of the group. This is 
the less to be regretted, as the student of this group must 
possess this most valuable memoir.

The author describes a very remarkable young form referable 
to Siphonophora, but which it Avould be impossible, until its 
further development is known, to refer to any known genus. 
Within this young form a small Siphonophorous colony was 
found suspended by a short cord. On one side was a portion of 
a swimming-column with the bells not yet differentiated ; and on 
the other was the axial filament, where the polyp- bodies would 
be developed ; each had a separate peduncle, and developed at 
its base stinging-filaments. 
The author describes the sea off Mentone in the early spring 
of 1868 as abounding in oceanic creatures.

This is only an abstract of a paper, in which the authors give
