Three examples of an Amyntas, unfortunately not fully mature, cannot, I believe, be included in any known species of the genus, though they come near to well-known forms with four pairs of spermathecae. The largest specimen measures 120 m m . and consists of about 120 segments. The anterior setae are at least not markedly larger than those upon the segments which follow. The position of the clitellum cannot be fixed. The only distinctive external feature of this species is the one which leads m e to separate it specifically. Between segments vii. and viii. are a closely-set row of small cup-shaped papillce, 8 on each side, a small space separating each 8. I took these at first for numerous spermathecal pores such as are found in A. stelleri and one or two allied forms. They are, however, only genital papillae, though of unusual position. Fig. 6. Anterior end of Amyntas evansi. X 4. The spermathecal pores, four pairs, are quite obvious, and lie to the outside of these papillae ; they are of course intersegmentally placed, and lie between segments v./ix. The male pores are placed upon very conspicuous porophores, which are widely separated and directed outwards, i.e. away from each other. There is no gizzard-septum. The last hearts are in xiii. The intestine commences in segment xv. and has a pair of cceca, which arise in segment xxvii. and extend forward so far as xxiv. or xxiii. The sperm-sacs are large in x., xi., xii.
