Show 628 MR. F. E. BEDDARD ON THE [May 22, the anterior segments ; those of segment x. very small; 34 on v., 60 on xxv. Setas ornamented. Spermathecae with long duct. Hab. Mexico, Madeira, Egypt, California. This species is placed among those with three pairs of spermathecae on account of the fact that one specimen had three pairs of these organs. But two pairs in viii. and ix. seems to be the more usual condition. It is not an easily definable species and may not be distinct. Its chief character (but this has not been looked for in many other species) is a series of vesicular bodies attached to the nephridia after segment xxx. 39. Amyntas udei Bosa. Perichceta udei, Bosa, Ann. Mus. Civ. Genova, (2) xvi. p. 521. Amyntas udei, Michaelsen, Jahrb. Hamb. wiss. Anst. xvi. p. 87. 66 mm., 90 segments. Setae closer ventrally ; 40 on vii., 39 on xxvi. 8 setae between male pores. Septum vii./ix. rudimentary. Spermiducal glands limited to xviii., with short slightly curved (S-shaped) duct. Diverticulum of spermatheca half the length of pouch. Hab. Sumatra. 40. Amyntas juloides Mich. Amyntas juloides, Michaelsen, Jahrb. Hamb. wiss. Anst. xvi. p. 5 3/ 145 mm., 119 segments. Setae with slight dorsal gaps, closer ventrally; 60 on vi., 86on xxv. Papillseone in frontof and one behind each male pore ; five median on xviii.; one on xvii., xix. Septum viii./ix. thin. Sperm-sacs with a median process. Spermiducal glands with slightly bent duct. Diverticulum of spermathecae less than pouch. Hab. Celebes. 41. Amyntas peguanus Bosa. Perichceta peguana, Bosa, Ann. Mus. Civ. Genova, (2) x. p. 113. Perichceta peguana, id. Ann. Nat. Hist. (7) ii. p. 289. 170 mm., 120 segments. Setae 56 on viii. Papillae on xvii./xviii., xviii./xix., paired in front of and behind male pores. Septum viii./ix. present. Spermiducal glands in three segments, with curved duct. Diverticula of spermathecae long but coiled into a tight coil, which cannot be separated. Bound sacs of muscular appearance corresponding internally to papillae. Hab. Burma, Penang, Siam. I do not agree with Bosa as to the absence of the septum viii./ix. I found it to be distinctly present in individuals examined by myself. 42. Amyntas flavescens Goto & Hatai.
