of the proboscis near the peduncle, ‘he remainder of the entoderm of the 
proboscis and of the tips of the marginal tentacles is green. 
Young Medusa. The youngest Medusa observed by us had only 4 oral ten 
tacles. The red color of the basal bulbs of the marginal tentacles extended for 
a considerable distance upward along the radial tubes. The bell was 1 mm. in 
height. 
This form is very abundant all over the Fiji Islands in November and De- 
cember. We came across a great swarm of these Medusæ within the crater of 
Totoya Island. 
Bougainvillea fulva, nov. sp.

Plate 2, Fig. 6. 
Generic Characters. Bougainvillea, Lesson, 1843. Margellidæ with dendriti- 
cally branching oral tentacles, and with 4 radially arranged bunches of mar- 
ginal tentacles, Proboscis wide and quadratic in cross section. Gonads 
developed in the ectoderm of the proboscis, 
Specific Characters. The bell is pyriform, and 2.5 mm. in height. The bell 
walls are of moderate thickness, There are 4 radially arranged bunches of 
marginal tentacles, each one of which consists of 3 tentacles. A dark pur- 
ple ocellus is found in the ectoderm of the tentacle bulbs at the base of each 
tentacle. The velum is well developed, There are 4 straight narrow radial 
canals. The proboscis is wide and quadratic in cross section. There are 4 
oral tentacles, each one of which branches dendritically twice. The gonads 
are found in the ectoderm of the proboscis. The entoderm of the tentacle 
bulbs and of the proboscis is flesh-colored. 
Single specimen, obtained in towing with an open net at 100 fathoms, three 
miles south of the mouth of Suva Harbor, December 16, 1897. 
Laodicea marama, nov. sp. 
Plate 3, Figs. 7, 8. 
Generic Characters. Laodicea, Lesson, 1848. Leptomeduse without otocysts, 
and with 4 simple unbranched radial canals, upon which lie the gonads, Ten- 
tacles numerous. The tentacle bulbs are well developed, and many of them 
possess ectodermal ocelli, There are clubs and cirri upon the bell margin, 
between the tentacles. 
Specific Characters, The bell is quite flat and disk-shaped, and is 5.5 mm. in 
diameter. There are about 50 long, slender, flexible tentacles, each one of which 
possesses a well developed basal bulb. A single dark purple ocellus is found 
upon the inner side of the bulb of most of the tentacles. This ocellus is situ- 
ated in the ectoderm, There are numerous clubs and cirri (Fig. 8) between 
the tentacles, The velum is prominent, There are 4 narrow radial canals, in 
the upper portions of which, near to the proboscis, the gonads are found. The 
proboscis is short and slender, and the lips not prominent, The entoderm of
