there is a well developed "tongue." Th? four heart-shaped gonads are found 
upon the radial canals immediately ab :)ve 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 ^^-ith nematocysts. 
Four broad radial canals. C-ircular vessel broad with four blindly ending 
centripetal diverticuhe. Four gonads at the middle of each of the four radial 
canals. Entoderm of manubrium green, lips and long hollow tentacles pink. 
Abundant in Bahamas, West Indies, and Tortugas. Occasionally drifted

Bell cylindrical 4 mm. high, with vertical sides and tlat top. Bell-walls 
very thin but ([uitc rigid. Tentacles numerous but very brittle, so that they 
are usually found to be broken otf s!iort. Eight small marginal otocysts. 
Velum well (leveloj)e<l. Ii]ight slender, stiaight, radial canals. Manubrium 
flask-shaped with four curved lips. A cylindrical peduncle above the manu- 
brium. Eight sausage-shaix'd gonads arise fnun the i)roxinuil part of the 
gastric portion of the manulu'ium. The entoderm of the nuinubrium is rosin- 
brown. Common in West Indian region and Tropical Atlantic.
