Perichceta novce britannice, Beddard, Willey's Zool. Results, pt. ii. 

 p. 183. 



130 mm., 120 segments. Setae 56 on vi., 74 on xxvi. Papillae, 

 two deep pits on xvii., xviii. Spermiducal gland in xvi.-xviii., 

 with straight duet ; orifices, as of the spermathecae, close. 

 Diverticulum as long as pouch. 



Hab. New Britain. 



F. Spermathecae 2 pairs in vii., viii. 



53. Amyntas tokioensis Beddard. 



Perichceta tokioensis, Beddard, Zool. Jahrb., Syst. Abth. vi. p. 762. 



Perichceta Candida, Goto & Hatai, Ann. Zool. Japon. ii. p. 77. 



Perichceta parvicystis, Goto & Hatai, ibid. iii. p. 18. 



70-150 mm., 67-95 segments. Setae 40. Papillae two to three 

 near male pores and paired on vi.— viii., with stalked glands. 

 Spermiducal glands (sometimes absent) xvii.-xx., with curved duct. 

 Spermathecal diverticulum long and straight. 



Hab. Japan. 



I think that there can be hardly a question as to the justice of 

 uniting the forms which have received the three names quoted 

 above. The fact that the spermiducal gland is absent in the form 

 termed by Goto and Hatai " Candida " is not necessarily an objection 

 to this proceeding. 



54. Amyntas hesperidum Beddard. 



Perichceta hesperidum, Beddard, P. Z. S. 1892, p. 169, and Fauna 

 Hawaiiensis, 1900. 



Perichceta sandvicensis, Beddard, P. Z. S. 1896, p. 203. 



Amyntas lohri, Michaelsen, Jahrb. Hamb. wiss. Anst. xvi. p. 12. 



100 mm., 105 segments. Setae stronger on anterior segments ; 

 33 on v., 53 on xvi. 18 setae between male pores. Septum viii./ix. 

 occasionally present, but thin. Spermiducal glands in three 

 segments. Diverticulum of spermatheca coiled, not long. Sperm- 

 sacs with dorsal diverticula. 



Hab. Hong Kong ; Hawaii ; Barbados. 



It is only the comparative shortness of the spermathecal appendix 

 that differentiates this species from ceruginosus ; the two are close. 



55. Amyntas hilgendorfi Mich.
