ing the bell opening, constricted just above the 4 small lips or mouth-amis, and bearing the ovaries ou 

 the proximal portion. Radial canals broad. 



Colors. The large tentacles light brown with a slight orange tinge at bases. There are bright 

 yellow pigment spots at the bases of the two rudimentary tentacles.

 (Proe. Elliott Soc.. vol. i, No. 1, p. 132.) 



Bell deep, orbicular, without apical prominence. Tentacles 2, very long, bearing stalked bat- 

 teries of nematocysts. There are also two rudimentary tentacles. Proboscis short and simple, with- 

 out expanded lips. Radial canals 4, not broad and bandlike, and with curious bulging groups of 

 nematocysts on the outside of the bell over the distal portions of the canals. 



Color*. Not given either in the original description or that of Dr. L. Murbach, who first estab- 

 lished the connection between Coi-jiiiitlx ni/iiialii! and (leuniuiria i/einniiixn of MeCrady, the latter being 

 the medusa of the former. His figures are here copied by permission.

Bell orbicular, marginal tentacles 2, long and hollow, alternately 

 with two eye-spots, which may indicate two rudimentary tentacles. 

 Proboscis short, not reaching much more than halfway to the broad and 

 strong velum. Radial canals 4, those leading to the large tentacles 

 broader than the others. 



Cvlnrx. Xot given by the describers. The medusa buds, while still

liell orbicular. Marginal tentacles 4, very long, each with a swollen 

 pigmented body at its base. Prolmscis very long, reaching far below the 

 l>ell opening when fully extended, but capable of Ix'ing retracted well 

 within the bell, suspended from the bell by a narrow, contracted por- 

 tion. Mouth a simple opening without mouth tentacles. The attached 

 medusa is longer, the tentacles closely coiled, and the proboscis retracted 

 within the bell and often having its walls distended with sexual products. 



Colors. Specimens in formalin have the proboscis and tentacle bulbs light yellowish, 

 black.
