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. lf 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 urceolatns Horst.

Spermathecae (occasionally a second pair in vii. present) with not coiled, not very long, diverticulum. Hab. Sumatra, Timor Cupang. H. Spermathecse 1 pair in viii. 15. Amyntas montanus Kinberg.
