(13) Amyntas evansi, n. sp. (Fig. 6.) 



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 mm. 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 caunot be fixed. 



The only distinctive external feature of this species is the one 

 which leads me to separate it specifically. Between segments vii. 

 and viii. are a closely-set row of small cup-shaped papittce, 8 on each 

 side, a small space separating each 8. 1 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.

The spermathecal pores, four pairs, are quite obvious, and lie to 

 the outside of these papillae ; they are of course intersegmentallv 

 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

The intestine commences in segment xv. and has a pair of ccuca, 

 which arise in segment xxvii. and extend forward so far as xxiv. or 

 xxiii. 



The sperm-sacs are large in x., xi., xii. The spermiducal glands
