BIGELOW : MEDUSAE FROM THE MALDIVE ISLANDS. 253 
this species much resembles Oceania pacifica Agassiz and Mayer (Bull. Mus. 
Comp. Zodl., vol. 32, no. 9), from Fiji. It differs from it strikingly, how- 
ever, in the possession of rudimentary tentacular bulbs on the bell margin, in 
which respect it resembles Oceania carolinae Mayer, from the western Atlan- 
tic, from which species it is clearly distinguished by the shape of the bell and 
the size and position of the gonads. 
Oceania brunescens, sp. nov. 
Plate 1, Fig 2. 
The bell is low and flat, about two mm. in diameter and one third as high. 
There are about thirty short thick tentacles, much swollen at the base. The 
bell margin does not bear tentacular bulbs. The proboscis is very short and 
broad, and the mouth bears four simple lips. The most distinctive feature of 
this Medusa are the gonads, which are exceedingly thick and prominent, and 
nearly hemispherical (Plate 1, Fig. 2). They occupy the proximal third of 
the radial canals. 
There are from thirty-two to forty small otocysts, each with one or two 
otoliths, scattered irregularly along the bell margin. 
The bell is colorless and very transparent. The canals and gonads are 
greenish yellow. ‘The tentacles are colorless, but at the base of each there is 
a prominent brown pigment spot. 
Two specimens, January 15, near the southern end of Malosmadulu atoll. 
The very large, hemispherical gonads and prominent brown pigment spots 
clearly distinguish this Medusa from all described species of Oceania. 
Hutimeta lactea, sp. nov. 
Plate 2, Figs. 7, 8. 
The bell is thin, slightly conical, nine mm. in diameter, and about one half 
as high. There are eight permanent and well-developed tentacles, of which 
the four opposite the radial canals are about as long as the diameter of the bell, 
and the other four slightly shorter. Small lateral spurs are borne at the bases 
of the tentacles, and there are in addition about twenty-four papillae on the 
bell margin. None of these bear lateral cirri. There are eight otocysts, each 
of which contains four or five otoliths. The peduncle of the proboscis is 
slender and slightly shorter than the bell diameter. The proboscis is cylin- 
drical and as long as 2 of the bell height. The mouth bears four slightly 
foliated lips. The position of the gonads is somewhat distinctive. They are 
borne on the radial canals, and occupy the central two thirds of the peduncle, 
as figured by Haeckel for Eutimeta gentiana (System der Medusen, 1880, 
plate 12, fig. 7). In Eutimeta levuka Agassiz and Mayer, from Fiji, they are 
found near the circular canal. The gonads are of considerable size, and form 
four swollen ridges.
