Setae 52 ; those of clitellum shorter and bifid at end. Spermathecae with longish, often zigzag diverticulum : with it open one or more glands. Hab. Sumatra, aud the East generally; Bahamas ; Madagascar l. The last three synonyms are not absolutely certain. The shape and occurrence of the clitellar setae is not noted by Michaelsen. At any rate this is the case with his original descriptions. But as he himself includes them as synonyms of A. houlleti in a recent paper, it is to be presumed that that point has been verified. The chief distinction between this species and the next is the peculiar form of the clitellar sette, which were originally figured by myself. 2. Amyntas travancorensis Fedarb. Perichceta travancorensis, Fedarb, Journ. Bombay Nat. Hist. Soc xi. p. 435. Perichceta crescentica, id. P. Z. S. 1898, p. 447. 80 mm., 101 segments. Setae upon clitellum not modified. 10-12 setae between male pores. Stalked glands associated with spermathecae, which latter have a zigzag diverticulum. Spermiducal glands much broken up in xvi.-xx. Hab. Dehra D u n and Travancore, in India; Sumatra (?). I think that there can be no doubt as to the identity of these two forms, which are among the few species of true Amyntas living in the Indian Peninsula. It may be that Horst's " Perichceta dubia "2 is this species. He describes it as generally like houlleti, but without any clitellar setae. In this case, the name will have to be altered. (2) Setce totally absent from clitellum ; gizzard-septa usually absent ; terminal bulbus present. A. Spermathecae 5 pairs in v.-ix. 3. Amyntas pentacystis Eosa. Perichcetapentacgstis, Eosa, Ann. k.-k. Hofmus. Wien, vi. p. 400. Amyntas pentacystis, Michaelsen, Jahrb. H a m b . wiss. Anst. xvi.' p. 95. 135-110 mm., 112-82 segments. Papillae on segments viii., xvii., xviii. paired. Setae 100 on viii. Both gizzard-septa present. Caeca absent. Spermiducal glands extend through three segments, with short bent duct, Spermathecae flattened " tomato-shaped,'' 1 Here as elsewhere I give a list of localities from which the several species have been obtained. I believe, however (with Michaelsen), that the occurrence ot the genus outside of the Oriental Eegion and Japan is accidental and due to man. , 2 Zool Ergebn.
