The darts (d) are each grooved through their entirelength, while upon the sheath (s/i) are fixed two guide rails, each like a prolongeddovetail, which, fitted into the groove, permits of no other movement than thatdirectly up and down. The darts are terminated by ten barbs of .ugly form(Z>, Fig. 194), and much larger than those of the sheath, and as soon as the latterhas established a hold, first one dart and then the other is driven forward bysuccessive blows. These in turn are followed by the sheath, when the dartsagain more deeply plunge, until the murderous little tool is buried to the these movements are the result of a muscular apparatus yet to be examined,and which has been dissected away to bring the ri
