VALLENTINIA. 



Vallentinia, Bbowne, 1903. 



Generic characters: Similar to Cubaia, excepting that the gonadB are 

 sac-like, and the otocysts are "enclosed inside the margin of the umbrella."* 



Species : 



V. falklandica ; Falkland Islands. 



Browne, 1902 ; Annal. Mag. Nat. Hist., Ser. 7, IX., p. 284. 



Olindias. 



Olindias, F. Mtjlleb, 1861. 

 Halicalyz, Fbwkes, 1882. 

 HaUcalyx, Matek, 1900. 

 OUndias, 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 Cubaia. There 

 are pad-like clusters of nematocysts on the aboral side near the distal ex- 

 tremity of the tentacles. These may or 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 otocysts are at the sides 

 of the tentacle-bases, above the velum, and project inward toward the bell 

 cavity. 

 Species : 



Olindias, MuUeri ; 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, Pis. I., II. 

 Description meagre. Figures lacking.
