Papillae paired and corresponding in position with male pores on xvii., xix.-xxi. Sperm-sacs in xii. Budiments of septum viii./ix. Spermiducal glands with short, very thick duct. Spermathecae with very short duct into which opens very short diverticulum. Hab. N e w Guinea. The anterior spermathecae were doubled on one side (the side differing) in the two specimens which I have examined. 99. Amyntas robustus Perrier. Perichceta robusta, Perrier, Nouv. Arch. Mus.

Sperm-sacs with dorsal process. Spermiducal glands with coiled duct. Diverticulum of spermatheca longer than pouch and moniliform at end. Hab. He de France ; Philippines. H. Spermatheca? 1 pair in viii. 100. Amyntas taprobanae. Perichceta taprobance, Beddard, P. Z. S. 1892, p. 163. Perichceta pauli, Michaelsen, Jahrb. Hamb. wiss. Anst. xiv. p. 87 ; id. Zool. Jahrb., Abh. Syst. xii. p. 140. 145 mm., 95-122 segments. Setae 70 on v., 54 on xxvi. Complete rings on all clitellar segments. Papilla? large, paired on vi.-xi. and xviii.-xxi. Septa? viii./ix. present. No caeca. Spermiducal glands small in xviii. only, with U-shaped duct. Spermatheca? small, with equally sized diverticulum. Hab. Ceylon. There is no doubt about the identity of these two species, accepted by Michaelsen. A re-exainination of the original specimens has shown the presence of the large faint papilla?. A characteristic of the species is the very small size of the generative apparatus. |
