periderm (?). Polypites fusiform, with two tentacula situated 
at the base of a two-lipped metastome. 
Gonosome not known. 
The remarkable and aberrant form described by Gosse under the 
name of Lar Sabellarum will need further investigation before it 
will be possible to determine its true affinities. I have retained it 
here, however, as a legitimate genus, and the type of a distinct family, 
though, with our present knowledge of it, we are almost tempted to 
regard it as an abnormal condition of some other form. 
Lar sabellarum, Gosse. 
Corynide, 
1. Corywne, Gartner. 
Trophosome.—Ccenosare consisting of a simple or branching 
hydrocaulus rooted by a creeping filiform hydrorhiza, the whole 
invested by a chitinous periderm. Polypites developed from the 
summits of the hydrocaulus, clavate; tentacles capitate, scat- 
tered on the body of the polypite. 
Gonosome.—Gonophores adelocodonic, developed from the 
body of the polypite.

Trophosome.—Ccenosare composed of a simple or branching 
hydrocaulus rooted by a creeping filiform hydrorhiza, and the 
whole invested by a chitinous periderm. Polypites claviform, 
developed from the summits of the hydrocaulus; tentacles 
capitate, scattered upon the body of the polypite. 
Gonosome.—Gonophores phanerocodonic, developed upon the 
body of the polypite. Umbrella, at time of liberation, deep bell- 
shaped ; manubrium moderately large, not reaching the mouth 
of the bell*, destitute of oral tentacles; radiating canals four ; 
marginal tentacles four, with bulbous bases, generally furnished — 
with an ocellus. In some cases the gonophores, though phane-

the Medusa at the time when it becomes free; it is probable, however, — 
that it ultimately assumes the type of Sarsia, with its greatly developed — 
and extensile manubrium. See Agassiz on Coryne mirabilis, in the fourth —
