Catostylus townsendi Mayer, 1915, Publication No. 212, Carnegie Institution of Washington, p. 183. This species is named in honor of the author's friend, Dr. Charles H. Townsend, the distinguished director of the New York Aquarium. Six specimens were found at Sta- tion D5594, September 30, 1909, about 6 miles off Mount Putri, Borneo, in 11 fathoms. Type, Cat. No. 28722, ; paratypes 28721, This medusa is closely allied to Catostylus purpurus of Manila Bay, Philippine Islands, but in formalin its exumbrella is milky in color and bespeckled irreg- ularly with numerous conspicuous purple-brown spots. The mouth- arms are more pointed than in G. purpurus. In some octants of the bell-margin the velar lappets are arranged as in G. purpurus, but they are usually more numerous and more irregularly arranged than in G. purpurus. The dimensions of the largest specimen of G. townsendi, stated in millimeters, are as follows: Bell 97 wide, flatter than a hemisphere, exumbrella finely granular, gelatinous substance of horny rigidity. Shape and consistency of the bell as in G. purpurus. Eight rhopalia without ocelli, in formalin, and with a deep dark-colored, furrowed, exumbrella pit. The rhopalar lappets are small and oval, but the velar lappets are about twice as wide as long. Deep clefts between the lappets extend a short distance up the sides of the exumbrella. The velar lappets are very irregular in arrangement, although they tend to conform to that seen in G. purpurus of Manila Bay, Luzon, yet in most of the octants the subdivisions of the principal lappets are more pronounced and irregular than in G. p
