It has, it will be observed, the slitlike suckers by the male pores, found, however, in other forms, such as A. novce-britannice. 35. Amyntas burchardi Mich. Amgntas burchardi, Michaelsen, Jahrb. Hamb. wiss. Anst. xvi. p. 88. 270 mm., 126 segments. Setae ornamented, larger anteriorly and also dorsally on all segments, with slight dorsal gaps ; 34 on v., 62 on xxvi. 40 small papillae between male pores. The sperm-sacs have a dorsal appendix. Spermiducal glands from xvii.-xxi., broken up into minute lobules, almost granular. Diverticulum slightly longer than spermatheca. Hab. Sumatra. The papillae suggest those of A. papulosus, with which, however, the present species (known by a single example only) is not to be confounded. 36. Amyntas ocellatus Mich. Amgntas ocellatus, Michaelsen, loc. cit. p. 89. 175 mm., 150 segments. Setae ornamented, larger on anterior segments; 28 on vi., 49 on xxvi. Papillae in two rows of 3-6 behind and before seta-line of xviii.; two in front of each spermathecal pore ; there are others varying in the same segments. Sperm-sacs with appendices. Spermiducal gland in four segments. Diverticulum hardly so long as spermatheca. Hab. Sumatra. 37. Amyntas tobaensis Mich. Amyntas tobaensis, Michaelsen, loc. cit. p. 91. 105 mm., 112 segments. Setae with slight dorsal gaps, closer ventrally; 54 on v., 47 on xxvi. Three small papillae by each male pore, and two or three pairs close to orifices of spermathecae. Sperm-sacs with an appendix. Spermiducal glands in xvii.-xx. Diverticulum coiled, half as long as spermatheca. Hab. Sumatra. 38. Amyntas californicus Kinberg. Pheretima californica, Kinberg, OZfv. K. Svensk. Ak.
