MEDUS.E OF THE WORLD. 



The 16 stomach-pouches break up into numerous forked, branched, radiating vessels 

 in the marginal lappets, hut their ultimate branches rarely anastomose. There are about 

 12 to 1 8 main branches from the outer edge of the stomach-pouch in each lappet and these 

 branch dendritically so that about 100 ramuh reach the bell-margin. There is no marginal 

 ring-canal.

The medusa is salmon-red or brownish-red, the canal-system being darker and the tenta- 

 cles light in color. When young the bell and tentacles are bluish and the curtain-like lips 

 salmon or brownish-red in color.
