Show 616 MR. F. E. BEDDARD ON THE [May 22, of that of Fletcher's P. darnleiensis. The peculiar investment of nephridial tubules to the spermatheca of martensi has not been described in the other forms with w hich I believe it to be identical: it remains the only difference, and tbat not perfectly certain. P. belli is difficult to separate. The diverticula of the spermathecae seem to be longer. Only one specimen, however, was examined. Michaelsen has described a var. javana. 5. Amyntas quadripapillatus Mich. Amyntas quadripapillatus, Michaelsen, Jahrb. Hamb. wiss. Anst. xvi. p. 93. 125 mm., 89 segments. Setae with slight dorsal gaps, closer ventrallv, 40 on v., 52 on xxvi. Large papillae on xvii., xix. on line with male pores. Spermiducal glands xvii.-xix.; terminal sac small. Diverticulum half the length of spermatheca. Hab. Sumatra. The arrangement of the genital papillae in this species strongly recalls that of A. posihumus. There can be no danger of confusing the two species. C. Spermathecae 3 pairs in vii.-ix. 6. Amyntas impudens Mich. Amyntas impudens, Michaelsen, Jahrb. H a m b . wiss. Anst. xvi. p. 84. 120 m m . (about). Setae with slight dorsal gaps, closer ventrally; 39 on vi., 58 on xxv.; those on anterior segments enlarged. Paired papillae on spermathecal segments. Terminal sac of spermiducal gland with extensive penis. Diverticulum of spermatheca longer than sessile pouch, slightly spiral, ending distally after narrow neck in a rounded seminal chamber. Hab. S.E. Borneo. Only a single specimen was studied. This appears to differ from the next species chiefly in the spermatheca which are sessile, and in the presence of papillae. 7. Amyntas philippinus Eosa. Perichceta philippina, Eosa, Ann. k.-k. Hofmus. Wien, vi. p. 397. Amyntas bindjeyensis, Michaelsen, Jahrb. Hamb. wiss. Anst. xvi. p. 94. 240 mm., 125 segments. Setae 44 on viii., 70 on xii. Sperm-sacs with narrow dorsal prolongations. Spermiducal glands not large, kidney-shaped, with short straight duct. Hab. Island of Cebu, Sumatra. I do not see any noteworthy differences in the descriptions of the two forms here united. I follow Bosa's description. Michaelsen figures the spermathecal appendix as coiled and probably longer than pouch. |
