Perichceta udeJcemi, Michaelsen, Arch. f. Naturg. 1892, p. 240. 



Perichceta gulielmi, id. Abh. Gebiete Naturw. xiii. No. 2, p. 32. 



200 ram. Setae 52 ; those of clitellum shorter and bifid at end. 

 Spermatheca? with longish, often zigzag diverticulum : with it 

 open one or more glands. 



Hah. Sumatra, and the East generally ; Bahamas ; Madagascar l . 



The last three synouyms 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 seta?, 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. Seta? upon clitellum not modified. 

 10-12 setee between male pores. Stalked glands associated with 

 spermatheca?, which latter have a zigzag diverticulum. Spermi- 

 ducal glands much broken up in xvi.-xx. 



Hub. Dehra Dun 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 clubia " 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. Spermatheca? 5 pairs in v.-ix. 



3. Amyntas pentacystis Bosa. 



Perichceta pentacystis, Eosa, Ann. k.-k. Hofmus. "Wien, vi. p. 400. 



Amyntas pentacystis, Michaelsen, Jahrb. Hamb. wiss. Anst. xvi. 

 p. 95. 



135-110 mm., 112-82 segments. Papilla? on segments yiii., 

 xvii., xviii. paired. Seta? 100 on viii. Both gizzard-septa present. 

 Caeca absent. Spermidtical 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 

 of the genus outside of the Oriental Region and Japan is accidental and due to 

 man.
