warts or papillae. 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 sphaerosomes 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 (o) 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 

 (rt, b), 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 (o). Tbe 

 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 {cl). 

 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 

 o])en. 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 eif^ht 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 Callinenia, or of the closely allied Phacellophora, has
