BAHAMA MEDUSJi]. 29 
A number of specimens of this medusa, in various stages of growth, were 
obtained at this time. They were all captured in a dredge at a depth of two 
fathoms, about one quarter of a mile off Brown's Point, Great Peconic Bay, 
where the bottom was covered with drifting seaweed. None were seen upon 
the surface. 
Adult Medusa, Tamoya Haplonema. 
Figs. G1-C4, Plate VII. 
Bell 90 mm. high, 55 mm. wide; with v(^rtical sides and relatively flat top. 
Exumbrella surface thickly covered with white wart like clusters of nomato- 
cysts. Four pedalia, 30 mm. long, wing-like and sharp-edged. Tentacles 90 
mm. long, hollow, very flexible, and bearing regularly spaced rings of nema- 
tocysts that are capable of inflicting a severe sting to the hand. The sensory 
clubs (Figs. 63, 04) have two large median, and four small lateral ej-es, all 
being upon the inner side of the bulb. The large eyes are provided with 
prominent convex lenses and are ectodermal. There is a large terminal 
entodermal otolith composed of a mass of concretions. 
The velarium is well developed, and there are ten dendritic velar canals 
in each quadrant which terminate in numerous, non-anastomosing branches 
(see Fig. 62). 
The nervous ring running from the base of each pedalium to the sensory 
clubs is distinctly visible as a white colored cord. 
The stomach extends about one-third of the distance from the inner apex 
to the level of the valarium, and there are four slightly recurved lips. The 
gastric cirri are short and numerous. 
The genital organs are curtain-like with frilled edges. They project from 
the interradial septde into the gastro-vascular pouches of the bell on either 
side. There are thus eight curtain-like sheets projecting into the four radial 
pouches. In old specimens the gonads are so large tliat their free edges 
overlap beyond the central line of each pouch. 
The gelatinous substance of the bell is transparent. The long, flexible 
tentacles are a milky yellow, often with a faint purple-hue. There are large 
white wart-like clusters of nematocysts over the pedalia and valarium. The 
genital organs are milkj^-yellow, and tlie eyes dark brown. 
This medusa is exceedingly active, and the gelatinous substance of its bell 
touoh and rigid.
