142 EXPEDITION OF THE "ALBATROSS," 1899-1900. 



long, and the small ones are mere rudiments. All of the tentacles arise 

 from the hell-margin. The basal bulbs of the long and intermediate ones 

 are conical, and each one bears a single ocellus upon its aboral side near the 

 base. The velum is well developed. There are four narrow radial tubes, 

 the mid-regions of which display jagged edges. The proboscis is bound to 

 the radial canals by means of four mesenteries. The proboscis is short and 

 extends only about one-half of the distance from the inner apex to the 

 velum. The gonads occupy four radially situated linear swellings, the 

 surfaces of which are complexly folded. The four lips are large and are 

 much folded. The proboscis and tentacle bulbs are of a delicate purple-pink 

 and the ocelli are dark red. A single specimen was found about 600 miles 

 north of the Marquesas.

The bell is 16 mm. in height, and the sides are barrel-shaped, being 

 wider at the middle than at either end. There is a small, solid, apical 

 projection. The bell walls are very thin and quite flexible. There are 

 about thirty short tentacles, all being of the same size. These tentacles all 

 arise from the bell-margin, and their bases are large and conical. There 

 are no ocelli. The velum is well developed. There are four radial tubes 

 which are flat and quite broad, being narrower near the circular canal than 

 at any other place. Their outer edges are jagged, excepting in the narrow 

 parts near the circular canal. The proboscis is large and fills the greater 

 part of the bell-cavity. It is bound to the four radial canals by means of 

 four mesenteries. The gonads occupy four radially situated double rows 

 which extend about two-thirds of the distance from the inner apex of the 

 bell-cavity to the velar opening. The outer surfaces of the gonads are 

 transversely folded and give rise to numerous papilla?. There are four well 

 developed, complexly crenulated lips. The lips and tentacle bulbs are of a 

 light port-wine color, and the gonads and radial canals are of a still lighter 

 shade. A single specimen of this medusa was found in a surface haul.
