Male pores 1*3 m m . apart. Clitellum xiii.- xvii. Groups of pores on segments x./xi., xviii./xix., xix./xx. Spermatheca? with longer diverticulum than last species. Hab. Philippines. These two species were first referred to the genus Megascolex, to which they have clearly many points of likeness. There are regular or irregular lines upon the dorsal and ventral surfaces which are uuoccupied by seta?. In any case these two species cannot be confounded with any others. There are no penial setae. For this reason and the position of the gizzard, the two forms appear to be rightly placed in the present genus. F. Spermathecae 2 pairs in vii., viii. 97. Amyntas godeffroyi Mich.
