Show 630 MR. F. E. BEDDARD ON TUB [May 22, of earthworms, should obviously include the specific names given above, which really only differ in size. Its characters, 6ave those of size, are by no means salient, and with difficulty can it be separated from the next species. I also place here A. willeyi, which cannot be, as is suggested by Michaelsen, a synonym of capensis since the latter has a terminal bursa. I am rather inclined to think that operculata (see p. 618) should come here. 45. Amyntas upoluensis Beddard. Perichceta upoluensis, Beddard, Proc. Boy. Soc. Edinb. xiv. p. 174, and Willey's Zoological Eesults, part ii. p. 185. Perichceta recta, Bosa, Ann. Nat. Hist. (7) xi. p. 284. 166 mm., 110 segments. Setae 46 on x., 54 on xxv. 7 setae between male pores. Papillae one median on x., and a variable number of also unpaired papillae on xvii.-xxi. (xxii). Two or three minute papillae close to each male pore. Spermiducal gland in xvi.- xviii.; duct short and straight. Diverticulum of spermathecae very long. Hab. Upolu, Esafate. 46. Amyntas sluiteri Horst. Perichceta sluiteri, Horst, Notes Leyd. Mus. xii. p. 234. 190 mm., 135 segments. Setae 60-75, more closely packed ventrally. Sperm-sacs x.-xii. Spermiducal gland nearly divided into two, of loose structure, its duct sinuous. Spermathecae with zigzag diverticulum as long as pouch. Hab. BilUtou. 47. Amyntas halmaherse Mich. Perichceta halmaherce, Michaelsen, Abh. Senck. nat. Ges. xxiii. p. 208. Perichceta jampeana, Benham, Ann. Nat. Hist. (6) xviii. p. 430. Amyntas jampeanus, Michaelsen, Jahrb. Hamb. wiss.

Papilla very variable in neighbourhood of male pores and spermathecal pores. Spermiducal gland not very large. Diverticulum longer than pouch. Hub. Celebes, Halmahera, Batjan. Dr. Michaelsen has indicated the close likeness which all the forms here brought together exhibit. He, however, would allow three species, viz., A. halmaherce, A. jampeanus, A. purpureus. The reasons for uniting all must now be dealt with. A. halmaherce (with varieties gamsungi, batjanensis, ccecilia, kauensis, galelensis, |
