reaching beyond the velum ; gonads of reddish orange color and arranged in 
four masses upon the manubrium. Hydroid generation, —a Dendroclava. 
Dysmorphosa fulgurans A. Ag. (FIG. 43). 
Bell subhemispherical, with slight conical apical projection ; radial canals 
four; marginal tentacles eight, symmetrically disposed; manubrium of 
medium size, its oral end provided with four 
rather prominent tentacles ; from the body 
of the manubrium secondary meduse bud 
off with great profusion, their numbers 
at times becoming so great as to afford 
a splendid phosphorescence (A. Agassiz).

Fic. 43. — Dysmorphosa fulgurans : 
A. Ag. (After A. Agassiz.) fodocoryne carnea Sars (FIG. 44). 
Medusa oval or bell-shaped or subglobular, form variable; exumbrella 
surface dotted with nematocysts ; size about five mm. in height by slightly 
more than half as broad ; marginal tentacles eight, four 
radial, four zz¢erradial, instead of all vadza/l, as stated 
in Part I in describing the gonosome of Podocoryne, 
the latter shorter; pinkish ocelli at bases of tentacles ; 
manubrium of medium size, though extensible to velum, 
of quadrangular form, with four oral lobes tipped with 
nematocysts ; gonads borne on base of manubrium. 
This medusa has been confused with the preceding, 
which has usually been designated as the product of 
Fic. 44.— Podocoryne Podocoryne. This is, 
carnea Sars. 
however, a mistake. 
Podocoryne, so far as I am aware, never 
produces proliferous meduse from the manu- 
brium, as is the case with Dysmorphosa. I 
have often followed the direct liberation of 
the meduse from the hydroid, and they have 
even at that time sex products well developed. 
Bunting has also noted the same thing. (Cf. 
Journ. Morph., Vol. IX.)

Bell subconical, its apex obtusely rounded ; 
radial canals four; marginal tentacles in eight clusters, the radial groups 
with five each, the interradial groups with three, in mature specimens ; 
young with only radial tentacles, one at each radius; there are no ocelli ;
