there is a well developed "tongue." The four heart-shaped gonads are found 

 upon the radial canals immediately above the circular vessel. The entoderm 

 of the manubrium is green. Common in the West Indies and Florida region 

 and occasionally drifted upon the New England coast in summer.

Bell bluntly conical, 7 mm. wide. Four long, hollow, tapering, radial tenta- 

 cles ringed at regular intervals. Four short-stiff, interradial, club-shaped ten- 

 tacles which project upward from the bell-margin. Eight otocysts on inner 

 side of bell cavity, one at base of each tentacle. Velum well developed. 

 Manubrium slender, about as long as the width of the bell. Peduncle short 

 and conical. Four lips, simple, cruciform, and studded with nematocysts. 

 Four broad radial canals. Circular vessel broad with four blindly ending 

 centripetal diverticulse. Four gonads at the middle of eac h of t he four radial 

 canals. Entoderm of manubrium green, lips and long hollow tentacles pink. 



Abundant in Bahamas, West Indies, and Tortugas. Occasionally drifted 

 northward to the southern coast of New England.

Bell cylindrical 4 mm. high, with vertical sides and flat top. Bell-walls 

 very thin but quite rigid. Tentacles numerous but very brittle, so that they 

 are usually found to be broken off short. Eight small marginal otocysts. 

 Velum Avell developed. Eight slender, straight, radial canals. Manubrium 

 flask-shaped with four curved lips. A cylindrical peduncle above the manu- 

 brium. Eight sausage-shaped gonads arise from the proximal part of the 

 gastric portion of the manubrium. The entoderm of the manubrium is rosin- 

 brown. Common in West Indian region and Tropical Atlantic.
