Soldier.—Only one soldier has been found with a pair of XA^-jointed organs (fig. 9, i), in both of which IV was very noticeably compound. They are therefore to be regarded as aberrant reductions of the XVI expression (fig. 9, h) and due to the fusing of IV, V thereof—i. e. (13 + 12). There are three types of XVI-jointed organs: one (fig. 9, h) in which III is short, a second (fig. 9, g) in which it is longish and compound, and a third (fig. 9,/) in which it is longish and simple. The XVII-jointed organs (fig. 9, e) are characterised by the smallness of III and the grossness of IV; it is very.
