Papillae paired on xvii./xviii., xviii./xix., corresponding with male pores, and three pairs on xix.-xxi. within line of male pores. Also anterior papillae upon viii. N o caeca. Both septa present. Spermiducal glands in three segments, with short straight duct. Diverticulum of spermatheca § length of pouch. Hab. Celebes. Only a single specimen is known. 85. Amyntas feae Bosa. Perichceta fece, Bosa, Ann. Mus. Civ. Genova, (2) vi. p. 161. 360 mm., 160 segments. Clitellum reaching to xvii. Seta? 100 on vii. Spermiducal gland with very long duct. Diverticulum of spermathecae zigzag. Hab. Tenasserim. 86. Amyntas glandulosus Eosa. Perichceta glandulosus, Bosa, Ann. Mus. Civ. Genova, (2) xvi. p. 607. Perichceta hippocrepis, id. ibid. p. 524. 110 mm., 130 segments. Setae 80 on viii., 70 on xxv. Setae on xvi. or all of clitellar segments. Male pores surrounded by many small papilla?. Similar papillae in front of and behind each spermathecal pore. Spermiducal gland in xvii.-xx., with curved duct. Spermathecal diverticulum zigzag, § length of pouch. Hab. Sumatra, Mentawei. I think there can be no doubt about the identity of these forms. The number of setae is stated to be different in the two; but this does not appear to be always a reliable character. The absence of papillae anteriorly in the form hippocrepis is again not necessarily a matter calling for specific rank. 87. Amyntas queenslandicus Fletcher. Perichceta queenslandica, Fletcher, Proc. Linn. Soc N . S. W . (2) i. p. 962. 120 mm., 120 segments. Seta? on all clitellar segments. Seta? 60. 14 setae between male pores. Papillae paired on ix.-xi. and xvii.-xxii. Sperm-sacs with dorsal appendices. Spermiducal glands large, in xviii.-xxi., with short duct. Diverticulum of spermathecae very short. Hab. Queensland. Mr. Fletcher is evidently not accurate in the enumeration of the segments in some of the organs. H e states that the spermatheca? are in v.-viii., which does not seem likely, especially as he states that the caeca are given off in xxv. Therefore I have some hesitation in copying his statement that the last pair of hearts is in xii., as this is, when certainly stated, rather an important specific character. |
