It differs, however, from both Euphysa and Corymorpha in the considerable 

 and equal development of the three short tentacles, and further study may prove 

 it to be representative of a new genus. 



Turritopsis, sp. 



A single young specimen of Turritopsis was taken in the tow on January 10, 

 in Felidu atoll. Species undetermined. 



Bougainvillia, sp. 



A single specimen of Bougainvillia, in a very fragmentary condition, was 

 taken in the tow on December 30, off the east face of Koluuiadulu atoll, in an 

 open net at one hundred fathoms. 



Berenice, sp. 



A single specimen of Berenice was taken in the tow on the night of Jan- 

 uary 8, in Haddummati atoll. It was too fragmentary for description. 



Oceania virens, sp. nov.

The bell is lenticular, with rather thin but firm gelatinous substance, about 

 twelve mm. in diameter and one third as higli. There are between sixteen 

 and twenty tentacles, the exact number being variable, irregularly arranged. 

 Each tentacle is thick, swollen at the base, only slightly contractile, and about 

 one half as long as the bell-height. Besides the tentacles there are from thirty 

 to forty rudimentary tentacular bulbs borne on the bell margin, two or three 

 between each two tentacles. These knobs, however, are irregulaily arranged, 

 and vary greatly in )iumber in different specimens. They appear never to be 

 developed into anything more than the mere rudiments of tentacles or cirri. 

 The proboscis is short, flask-shaped, very distensible, and bears four simple 

 pointed lips. The gonads are long for this genus, occupying the distal half of 

 the radial canals. 



There are thirty-two otocysts, two or three between each pair of tenta- 

 cles, but rather irregularly distributed. Each contains one or two spherical 

 otoliths. 



The bell is colorless. The gonads, proboscis, and tentacles are light yellow- 

 ish green. 



Several specimens, December 26, Male atoll, near Male island, and Janu- 

 ary 2 in Suvadiva atoll, near Dandu island, surface.
