has described both, I separate them here. But the present form 

 is known only from one specimen, and may prove to be not 

 different from A. castaneus. It has, it will be observed, the slit- 

 like suckers by the male pores, found, however, in other forms, such 

 as A. novce-britannice.

270 mm., 126 segments. Setae ornamented, larger anteriorly 

 and also dorsally on all segments, with slight dorsal gaps : 34 on v., 

 62 on xxvi. 40 small papillae between male pores. The sperm-sacs 

 have a dorsal appendix. Spermiducal glands from xvii.-xxi., broken 

 up into minute lobules, almost granular. Diverticulum slightly 

 longer than spermatheca. 



Hab. Sumatra. 



The papillae suggest those of A. papulosus, with which, however, 

 the present species (known by a single example only) is not to be 

 confounded.

Amyntas ocellatus, Michaelsen, loc. cit. p. 89. 



175 mm., 150 segments. Setae ornamented, larger on anterior 

 segments'; 28 on vi., 49 on xxvi. Papillae in two rows of 3-6 behind 

 and before seta-line of xviii. ; two in front of each spermathecal 

 pore : there are others varying in the same segments. Sperm-sacs 

 with appendices. Spermiducal gland in four segments. Diverti- 

 culum hardly so long as spermatheca. 



Hab. Sumatra.

105 mm., 112 segments. Seta? with slight dorsal gaps ; closer 

 ventrally; 54 on v., 47 on xxvi. Three small papillae by each male 

 pore, and two or three pairs close to orifices of spermatheca. 

 Sperm-sacs with an appendix. Spermiducal glands in xvii.-xx. 

 Diverticulum coiled, half as long as spermatheca. 



Hab. Sumatra.
