ANTHOMKDU.S.E PANDEA. 



II '.I 



ubrium is slender and about half as long as the depth of the bell-cavity. 4 small lips. 4 

 longitudinal gonads on the stomach. These are narrow folds with smooth outer surfaces. 

 Bell light-pink, with the 8 adradial lines of nematocysts more intense in color. Stomach and 

 tentacle-bulbs light-brown. 



Found in Sydney Harbor, New South Wales, Australia, in August and September.

Bell pear-shaped and 7.5 mm. high, with moderately thick 

 walls. There are about 32 tentacles. 8 to 12 of these are 

 about 3 times as long as the bell-height and 24 are small and 

 rudimentary. The long tentacles are all of equal length. Their 

 basal bulbs are long, tapering, and hollow. There are i to 3 rudi- 

 mentary tentacle-bulbs between each successive pair of long ten- 

 tacles. There are about 32 ectodermal, purple ocelli, one on tin- 

 outer side of each tentacle-bulb. The velum is well developed. 

 The manubrium is flask-shaped and quadratic in cross-section. 

 The outer surfaces of the adradial gonads are smooth and with- 

 out corrugations (plate n, fig. 7). The mouth is at the extrem- 

 ity of a well-developed neck and is at about the level of the velar 

 opening. There are 4 large, slightly recurved lips with smooth, 

 simple edges. There are 4 straight, narrow radial-canals and a 

 broad circular vessel. The entoderm of the manubrium and ten- 

 tacle-bulbs is delicate pink and in some specimens a green streak 

 extends along the outer surface of the entodermal lining of the 

 radial-canals. This medusa is common at the Tortugas, Florida, 

 and among the Bahamas throughout the summer. An appar- 

 ently identical species is found at Suva in the Fiji Islands, South 

 Pacific, although the Pacific medusa is not so highly colored. 



A closely related, if not identical, medusa is described by 

 Lobianco, 1903, from two specimens drawn from depths of 500 to 

 600 fathoms near Capri, Bay of Naples, Italy. Dr. Lobianco 

 kindly permitted me to studythese specimens. The bell is 1 1 mm. 

 high, 7 mm. wide; thick-walled, with dome-like apex. There are 

 12 to 13 long tentacles, 4 to 5 times as long as the bell-height. 

 These have long, hollow, tapering basal bulbs, each with an 

 abaxial, dark-red ectodermal ocellus. In addition to the long 

 tentacles there are about 24 to 36 very short rudimentary marginal 

 tentacles, each with an abaxial ocellus. The 4 radial-canals are 

 quite wide and with slightly jagged outlines. The manubrium 

 is half as long as the depth of the bell-cavity. The 4 complexly 

 folded lips are at the end of a well-developed neck. The outer 

 surfaces of the adradial gonads are smooth. The entoderm is 

 strawberry-pink. I can not separate this medusa from Pandea 

 violacea of Tortugas, Florida, some specimens of which are fully 

 as pink in color as is the one shown in Lobianco's figure.

Bell 10 to 13 mm. high and only about half as wide as high, with a smooth exumbrella 

 surface. Bell-walls quite thick, with an evenly rounded apex, without an apical pro]i-ctmn. 

 4 thick, hollow tentacles at the bases of the 4 radial-canals. These have large, swollen basal 

 bulbs, but no ocelli were observed. The tentacles are about as long as the bell-height and
