D. Spermathecae 2 pairs in vii., viii. 



8. Amyntas ferdinandi Mich. 



Perichceta ferdinandi, Michaelsen, Jahrb. Hamb. vviss. Anst. 

 viii. p. 336. 



190 mm., 116 segments. Setae 55 in middle of body. Male 

 pores somewhat approximated, one-sixth of circumference apart. 

 Spermiducal gland in xvii.-xix., duct bent. Spermathecae with 

 two shortish diverticula. 



Hah. 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 pura, Eosa, 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. 



Hah. Louibok. 



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)

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. 



Hah. 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 the 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.
