Setae of anterior segments stronger, 33 on v., 48 on xxv. Paired papillae 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. Hab. Japan. I take the above description entirely from Michaelsen. H e is of opinion that the species described by Messrs. Goto and Hatai enumerated 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 investigation 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 izukai, 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 fine with male pores. Caeca absent. Spermiducal glands confined to xviii. Spermathecae with long duct and equally long appendix. Hab. Japan. , The disposition of the genital papillae in this species is like that of A. forbesi and A. biserialis. But the four pairs of spermathecae distinguish tbe present species from either of those. 29. Amyntas bosschae Horst. Perichceta bosschee, Horst, Notes Leyd. Mus. xv. p. 324.
