27. Amyntas divergens Mich. 



Perichceta divergens, Michaelsen, Arch. f. Naturg. 1892, p. 243. 



Amyntas divergens, id. Jahrb. Hamb. wiss. Anst. xvi. p. 8. 



P. fuscata, P. keteropoda, P. obscura, P. scholastica, P. micronaria, 

 P. grossa, Goto & Hatai, Ann. Zool. Jap. ii. p. 66, &c. 



120 mm., 120 segments. Setae of anterior segments stronger, 

 33 on v., 48 on xxv. Paired papilla? on vii.-ix. near spermathecal 

 pores, to which correspond internally stalked glands ; also on 

 xvii.-xx. Sperm-sacs with dorsal process. Spermiducal gland, 

 totally absent. 



Hub. Japan. 



I take the above description entirely from Michaelsen. He is of 

 opinion that the species described by Messrs. Goto and Hatai enu- 

 merated above are to be looked upon as mere variations. To these, 

 indeed, he adds some few others which I partly identify with other 

 known forms of Japanese Amyntas. This arrangement, however, 

 cannot but be regarded as quite preliminary. A renewed investi- 

 gation of the Japanese species is to be desired. 



In the meantime it may be mentioned that in P. fuscata, 

 P. scholastica, P. grossa, and P. micronaria there is a spermiducal 

 gland. But this of course is no reason against the identification 

 of the various forms here grouped together as one species. 



28. Amyntas izukai Goto & Hatai. 



Perichceta izuhai, Goto & Hatai, Ann. Zool. Jap. iii. p. 14. 



235 mm., 137 segments. Setae 40 on v., 60 posteriorly, longer 

 on anterior segments. Paired papillae on xix.-xxiii. in line with 

 male pores. Caeca absent. Spermiducal glands confined to xviii.. 

 Spermathecae with long duct and equally long appendix. 



Hub. Japan. 



The disposition of the genital papillae in this species is like that 

 of A. forbesi and A. bisericdis. But the four pairs of spermathecae 

 distinguish the present species from either of those. 



29. Amyntas bcsschae Horst.
