13. Amyntas schmardse Horst. 



Megascolex schmardce, Horst, Notes Leyd. Mus. v. p. 194. 



Perichceta schmardce, Michaelsen, Arch. f. Naturg. 1892, p. 235 ; 

 id. Zool. Jahrb. xii. p. 224. 



P. trityphla, Beddard, P. Z. S. 1896, p. 205. 



P. vesiculata, Goto & Hatai, Ann. Zool. Jap. iii. p. 21. 



80 mm., 93 segments. Anterior setae slightly larger ; 38 on vi., 

 49 on xvii. No papillae. Caeca trifid or even with five divisions. 

 Sperm-sacs with dorsal constricted portion. Spermiducal glands 

 xvii.-xxi., much incised. Diverticulum of spermathecae long and 

 coiled. 



Hab. Japan, Barbados, Honolulu, Oahu, China. 



I think that Michaelsen is fully justified in uniting the species 

 referred in the above synonymy ; though it must be remembered 

 that the trifid or multifid caecum of my trityphla was not described 

 by Horst in the type of his schmardce. If it were not for this 

 feature, the species could hardly be separated from A. capensis. 



P. vesiculata of Goto and Hatai seems to me to be probably this 

 species. The complex caeca agree with this identification, as do 

 other points. The only difference in the descriptions of the two 

 Japanese authors is in the position of the spermathecae, which are 

 said to be vii., viii. To a Chinese variety with rather fewer setae 

 per segment, closer packed ventrals, Michaelsen gives the name 

 var. macrochceta. 



G. Spermathecae 1 pair in vi. 



14. Amyntas urceolatus Horst. 



Perichceta urceolaia, Horst, Notes Leyd. Mus. xv. p. 322 ; Bosa,

110 mm. Setae 30-40. 12 setae on v. between male pores. 

 Sperm-sacs with dorsal median process. Spermathecae (occasion- 

 ally a second pair in vii. present) with not coiled, not very long, 

 diverticulum. 



Hab. Sumatra, Timor Cupang.
