References have been made to Cone Shells shooting or ‘‘spitting out’? the 
denticles which bury themselves into the vietim’s flesh. This is unlikely. Tt 
seems more likely that the proboscis is extended, and the radula protruded, and 
the denticles quickly thrust into the flesh. Cumings, 42, deseribed an attack by

Conus textile on an Octopus in an aquarium. He remarks, ‘‘ When the radula is 
protruded, it is seen directly beneath the siphon.’’ Clench and Kondo, 120, in de- 
seribing the anatomy of Conus striatus state, ‘‘Iu the median crop or the narrow 
connecting tube was a well-preserved tooth of the Conus itself, which is without 
doubt the one used to kill the now partially digested prey.’’ The proboscis in 
Floraconus anemone is well-provided with longitudinal and retractor muscles. 
The action of the barb in Floraconus anemone would then be, as suggested 
in the diagram, to enter and then anchor in the flesh, The barb catch- 
ing would bend over the sharp point of the dentiele at the narrow neck 
near the tip when the tooth would be torn from the radula at the base.
