Show 1900.] EARTHWORMS OF THE GENUS AMYNTAS. 617 D. Spermathecae 2 pairs in vii., viii. 8. Amyntas ferdinandi Mich. Perichceta ferdinandi, Michaelsen, Jahrb. Hamb. wiss. Anst. viii. p. 336. 190 mm., 116 segments. Setao 55 in middle of body. Male pores somewhat approximated, one-sixth of circumference apart. Spermiducal glaud in xvii.-xix., duct bent. Spermathecae with two shortish diverticula. Hab. Sangir. This species seems to differ from its allies by the position of the spermathecae. The presence of an additional diverticulum suggests a gland such as that of A. houlleti. Only two examples were examined. 9. Amyntas purus Eosa. Perichceta pur a, Rosa, Ann. Nat. Hist. (7) ii. p. 285. 250 mm., 92 segments. Setae 54 on v., 96 on xxv., 14 between male pores. Sperm-sacs with dorsal appendages. Spermiducal glands enclosed in xviii., with short duct. Spermathecae with long diverticulum, the duct of which is thicker at its lower half, as in A. stelleri. Hab. Lombok. Of this species but one specimen is known. E. Spermathecae 3 pairs in vi.-viii. 10. Amyntas merabahensis Beddard & Fedarb. Perichceta merabahensis, Beddard & Fedarb, Ann. Nat. Hist. (6) xvi. p. 72. 200 mm., 146 segments. Male pores rather close. Caeca small. Sperm-sacs x.-xii. Spermathecae with long diverticulum closely coiled, ending in a globular sac. Spermiducal glands xix.-xxii. Hab. N. Borneo. This species has diverticula like those of A. peguanus. The duct is much contorted, but cannot be dissected out. It has the appearance of being contained within a sheath. The spermiducal glands are unusual in tbe fact that they lie entirely behind their duct and of course the terminal bursa. They are much broken up into lobules. F. Spermathecae 2 pairs in viii., ix. 11. Amyntas capensis Horst. Megascolex capensis, Horst, Notes Leyd. Mus. v. p. 195. Perichceta capensis, Horst, in M a x Weber's Zool. Ergebn. ii. p. 62 ; id.
