are in close proximity to each other at the base of the double feelers. 
The male are the least numerous, the form oval, slightly medusan, 
the nucleus as it ripens passing from red to yellow; there are four 
-Yadial canals and a circular canal, the mantle lying close to the 
nucleus and having an opening. The female appendages are smaller 
and round, but of similar structure, except that the central vessel of 
the nucleus is not developed, for each appendage contains only a 
single egg. Compare the interesting observations and figures of

Forskalia Kor.urxKer. 
Sp. Forskalia Edwardsii Koxut. This new genus and species differs little, if 
at all, from Stephanomia according to LEUCKART. See the description and 
beautiful figures in Kornrixer Die Siphonophoren v. Messina, s, 2—r0.

Agalmopsis Sars. Swimming column formed of two rows of 
bells alternating. Below it, the stem gives origin to single Polyps, 
feelers, prehensile filaments and sexual organs with numerous 
transparent bracts or covers.

The prehensile filaments give off branches which again subdivide to terminate 
in two threads: a contractile bladder is seated below the point of last divi- 
sion, and immediately before this is a spiral nettle-node covered by a bell- 
shaped duplicature from the filament on which it is placed. Aygalmopsis 
punctata Kont., a new species, differs from the last in the branches of the 
prehensile organs having the node without a cover, and in terminating 
without further division: also the feelers haye special prehensile organs 
which are knotted. 
Agalma Escuscu. Swimming column with bells in two rows : 
feelers scattered. Polyps with bracts and prehensile organs of 
which the lateral branches are provided with a large nettle-node 
and subdivide to terminate in two threads having a contractile 
vesicle between them at the division. |
