VALLENTINIA. 
Vallentinia, Bkowne, 1902. 
Generic characters: Similar to Cubaia, excepting that the gonads are 
sac-like, and the otocysts are "enclosed inside the margin of the umbrella."* 
Species: 
V. falklandica ; Falkland Islands. 
Browne, 1903 ; Auual. Mag. Nat. Hist., Ser. 7, IX., p. 284. 
Olindias. 
Olindias, F. Muller, 1861. 
Halicalyx, Fewkes, 1882. 
Halicalyx, Mayer, 1900. 
Olindias, Goto, 1903. 
Generic characters : The tentacles are of two sorts. Those of one sort 
arise from the bell-margin, while those of the other set project from the sides 
of the bell, in a zone above the margin, as in Gonionemus and Cnbaia. There 
are pad-like clusters of nematocysts on the aboral side near the distal ex 
tremity of the tentacles. These mayor may not function as adhesive disks. 
The gonads are papilliform. There are four complete radial canals, and a 
number of blindly ending centripetal canals. The otoc^'sts are at the sides 
of the tentacle-bases, above the velum, and project inward toward the bell 
cavity. 
Species: 
Olindias, Mulleri ; Mediterranean.

OLINDIOIDES. 
Olindioides, Goto, 1903. 
Generic characters : Two sets of tentacles. Those of one set arise from the 
bell-margin, are highly contractile and armed with partial rings of nemato- 
cysts. The tentacles of the other set project at various levels from the sides 
of the bell, their entodermal cores traversing the gelatinous substance. They 
each bear an adhesive patch of ectodermal cells at or near their extremities; 
six gonads, one on each radial canal, ribbon-like, and folded; six complete 
radial canals, and numerous blindly-ending centripetal vessels. Otocysts as 
in Olindias. 
Species : 
Olindioides formosa, Misaki, Japan. 
Goto, S., 1903; Mark Anniversary Volume, p. 1-22, Tls. I., II.
