or subulate ; or wart-like ; or wider at the tip than at the base ; or 

 forming short stems with spherical heads. Only one tentacle per exocoel, 

 a good many on each endocoel, usually more than one row abreast per 

 endocoel ; the rows may be very irregular. Sphincter weaker or stronger, 

 circumscribed diffuse to well circumscribed. A cleft tentacle sometimes 

 occurs among the others. Siphonoglyphes and directives variable in 

 number.
