Traces of clitellum begin on segment 13, but bceome 

 strongly marked on segments 14-33, 36 ( = 23 somites). 

 The ebtellar somites 25-32^ bear latcro-ventral Aving-like 

 expansions with either a straight or greatly-folded margin. 

 The limits of the clitellum at either end arc indistinct. The

 The •■section shows the immense dorsal thickening of the pharvn<real 

 wall, the ventral thrown into folds so as to give rise to poueh-like 

 sacs.

puberty-tubercles occur in three rows in front of the clitellar 

 fold, and their number and relation to somites are irregular. 

 The mid-ventral row commences on segments 13, 16, extend- 

 ing up to segments 23, 24. The number of lateral papillae
