Note 8. Telson with six terminal spines, but there will be five terminal spines in the following stage. 

 There is no projection into the existing spine on the extreme left. 

 As in Note 6. 



On the telson the outermost terminal spine on the right is a very small vestige, about one-tenth 

 the length of the spine next to it. Within the integument there are four projections into the spines; 

 there is no projection into the small spine on the right nor into the outermost on the left (see 

 Fig. 12 b). 



As in Note 6. 



Of the six terminal spines on the telson the outermost on the left is half the length of that next 

 to it. The number of spines in the following stage is four large normal spines and a very small fifth 

 one on the extreme right. The latter may atrophy altogether, so that only four spines may be present 

 in the succeeding stage (see Fig. 12 c). 



Of the seven terminal telson spines, the outermost on the right is one-fifth the length of the next 

 to it, the outermost on the left is about three-quarters the length of that next to it. The remaining 

 spines are subequal with a slight reduction in the size from the outermost to the central (see 

 Fig. 12 d).
