316 MR. F. E. BEDDARD ON THE [May 22, 



of that of Fletcher's P. darnleiends. The peculiar investment of 

 nephridial tubules to the spermatheca of marteusi has not been 

 described iu the otber forms with which 1 believe it to be identical : 

 it remains the only difference, and that not perfectly certain. 

 P. belli is difficult to separate. The diverticula of the spermathecae 

 seem to be longer. Only one specimeu, however, was examined. 

 Michaelsen has described a var. javana. 



5. Amyntas quadripapillatus Mich. 



Amyntas quadripajnllatus, Michaelsen, Jahrb. Hamb. wiss. 

 Anst. xvi. p. 93. 



125 mm., 89 segments. Seta? with slight dorsal gaps, closer 

 ventrally, 40 on v., 52 on xxvi. Large papilla?' on xvii., xix. on 

 line with male pores. Spermiducal glands xvii.-xix. ; terminal 

 sac small. Diverticulum half the length of spermatheca. 



Hab. Sumatra. 



The arrangement of the genital papillae in this species strongly 

 recalls that of A. posthumus. There can be no danger of confusing 

 the two species. 



C. Spermatheca? 3 pairs in vii.-ix. 



6. Amyntas ixnpudens Mich. 



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

 p. 84. 



120 mm. (about). Seta? with slight dorsal gaps, closer ventrally ; 

 39 on vi., 58 on xxv. ; those on anterior segmeuts enlarged. 

 Paired papilla? on spermathecal segments. Terminal sac of 

 spermiducal gland with extensive penis. Diverticulum of sperma- 

 theca longer than sessile pouch, slightly spiral, ending distally 

 after narrow neck in a rounded seminal chamber. 



Hab. S.B. Borneo. 



Only a single specimen was studied. This appears to differ 

 from the next species chiefly in the spermatheca which are sessile, 

 and in the presence of papilla?. 



7. Amyntas philippinus Bosa. 



Pericha'ta philippina, Bosa, Ann. k.-k. Hoftnus.Wien, vi. p. 397. 



Amyntas bindjeyensis, Michaelsen, Jahrb. Hamb. wiss. Anst. 

 xvi. p. 94. 



240 mm., 125 segments. Seta? 44 on viii., 70 on xii. Sperm- 

 sacs with narrow dorsal prolongations. Spermiducal glands not 

 large, kidney-shaped, with short straight duct. 



Hab. Island of Cebu, Sumatra. 



I do not see any noteworthy differences in the descriptions of 

 the two forms here united. I follow Bosa's description. 

 Michaelsen figures the spermathecal appendix as coiled and 

 probably longer than pouch.
