Character.— Mi^Q[\Q,A. to their prey by means of two 

 long appendages which arise from the thorax. They 

 unite together either at the base or near the tip only, and 

 terminate there in a rounded knob like a button, by 

 means of which the animal maintains its hold of the part 

 to which it has attached itself. No thoracic feet, or they 

 are represented by these arm-shaped appendages.
