section, and there are four slightly recurved lips. The four gonads are 

 found upon tlie four radial canals very near to the circular vessel. In the 

 single specimen obtained, each gonad contained from six to eight prominent 

 eggs. The medusa is transparent with the exception of the proboscis gonads 

 and tentacle bulbs, which are translucent and milky in color. This form 

 was found in the lagoon of Rangiroa Island, Paumotus, on September 23, 

 1899.

 The bell is much flatter than a hemisphere, and is about 16 mm. in 

 diameter. The gelatinous substance is thick at the aboral pole, but becomes 

 thinner towards the bell-margin, which is sharp-edged. There are about 

 fifty-six hollow tentacle bulbs. Four of these are large, and are situated at 

 the bases of the four radial canals. Twelve others are of medium size, and 

 three of these are found in each quadrant. In addition to these there are 

 about forty very small rudimentary tentacle bulbs upon the bell-margin. 

 There are no lateral or marginal cirri. There are about fifty-six otocysts 

 which alternate in position with the tentacle bulbs. Each otocyst contains 

 two or three spherical otoliths. The velum is well developed. There are 

 four simple, narrow, radial canals, and a slender circular vessel. The pedun- 

 cle is about as long as the bell-diameter, and projects a considerable distance 

 beyond the bell-opening. The basal part of the peduncle has the shape of a 

 four-silled truncated pyramid, while the distal portion is long, and tapers 

 gradually toward the gastric part of the proboscis. The four radial canals 

 extend down the angles of the peduncle to the gastric portion of the 

 proboscis. The latter is .short and flaring, and there are four well developed, 

 recurved, cremdated lips. The gonads are linear, and are developed upon 

 the sub-umbrella regions of the radial canals. The entoderm of the tentacle 

 bulbs and gonads is pink in color, while that of tlie gastric portion of the 

 proboscis is rosin-yellow. A single specimen of this medusa was found in 

 an open net which was towed from a depth of 150 fathoms to the surface, 

 off Funafuti Atoll in the Ellice Islands.
