warts or papillz. Walls of the bell transparent, with conspicuous radiating 
tubes. 
The radial tubes (Fig. 3) are of two forms: those which lie in the radius of 
the sense bodies, which are more or less anastomosing. and branching; while 
those in intermediate spherosomes are unbranched, straight, and almost paral- 
lel with each other. Tubes broad, slightly brown color, extending from the 
stomach cavity to the marginal vessel. There are sixteen sets of anastomosing 
tubes and the same number of unbranched vessels. The former lie in the radii 
of the sense bodies of the bell margin. The marginal vessel is continuous, 
obscurely sinuous, broad, without lobes. 
There are sixteen hooded (Fig. 5, v) sense bodies on the bell margin. Each 
marginal sense body (0) is pearl-white and conspicuous. The intimate structure 
is like that of P. sicula, described by the Hertwigs.* The rim of the bell 
between each pair of marginal sense bodies (Figs. 4, 5) is filled by a broad lobe 
(a, 6), the margin of which is indented and incised or scalloped. The sixteen 
marginal lobes are separated by deep incisions, at the deepest part of which lie 
the marginal sense bodies. The marginal lobes are penetrated by blindly end- 
ing vessels or tubes (cr), which arise from the circular tube (cl) between and 
among the tentacles. These blind tubes of the marginal lappets are sometimes 
slightly bifurcated at the end, and sometimes send off small lateral serrations. 
They are never branched, nor anastomosing. The tube which arises from the 
marginal circular vessel in the radius of the otocyst divides into three divisions 
shortly after it leaves the point of origin. The median, or smallest of the 
three divisions, extends into the cavity of the style of the otocyst (0). The 
two lateral divisions (ch) are somewhat bow-shaped and follow along the side 
of the cleft in which the margin of the bell is incised for the otocyst. The 
cavity of the two bow-shaped divisions (ch) is entire on the inner border, and 
more or less serrated on the side turned toward the marginal cleft in which the 
otocyst lies. 
The tentacles (p) are numerous, and arise, not from the edges of the mar- 
ginal lappets, but from the neighborhood of the circular marginal vessel (c/). 
The tentacles vary very greatly in size, and are placed side by side (Figs. 3, 4) 
along the circular tube into which, alternating with the marginal vessels, they 
open. Each tentacle is long and somewhat flat, with a finely scalloped double 
edge of white color. There are from eight to ten tentacles between each pair 
of marginal sense bodies. 
The mouth lobes (ga) resemble those of Cyanea, and consist of folded cur- 
tains of yellow and brown color. The walls of the actinostome are more or 
less extended outward (Fig. 1), and the lips are entire. 
There are eight large sexual bodies (sp) hanging at the base of the mouth 
parts near their attachment. These structures are prominent and have a 
brownish color. The sexual filaments are large and conspicuous. 
No other species of Callinema, or of the closely allied Phacellophora, has
