432 OLIGOCHAETA 



(73) Perichaeta tenkatei, HORST. 



P. tenkatei, HORST, loc. cit., p. 321. 



Definition. Length, 85 mm.; number of segments, 100; 50 setae in segments near to 

 clitellum. Clitellum without setae. Dorsal pores begin XT/XII. Spermathecae in VIII, 

 IX with, long ^-shaped diverticulum longer than pouch. Spermiducal glands terminating 

 in a small dilated sac. Hab. Soemba. 



This species has the male pores upon large papillae, and there is a kind of lid 

 to each pore as in P. capensis. Above the ovaries in xiii is apparently an egg-sac. 



(74) Perichaeta urceolata, HORST. 

 P. urceolata, HORST, loc. cit., p. 322. 



Definition. Length, no mm. ; 36-40 setae upon each segment. Clitellum without setae. 



Male pores separated by twelve setae. Spermiducal glands with terminal sac. Hab. 



Sumatra. 



This species is unusual in having only a single pair of spermathecae ; but in one 

 specimen there was additional though much smaller pair in vii. The pouch was 

 found by HORST to contain ' sand and other strange material.' 



(75) Perichaeta bosschae, HORST. 

 P. bosschae, HORST, loc. cit., p. 324. 



Definition. Length, 170 mm.; number of segments, 125. Dorsal pores begin XIT/XIII. 

 Clitellum without setae. Spermathecae in VI-IX with small diverticulum. Hab. 

 Borneo. 



(76) Perichaeta tijibodae, HORST. 

 P. tijibodae, HORST, loc. cit., p. 326. 



Definition. Length, 50 mm. Setae, 44 per segment. Clitellum without setae. Male pores 

 separated by eight setae. Spermathecae in VIII, IX, with diverticulum curved like a 

 ram's horn. Spermiducal gland extends over segments XVI-XXII ; it has a terminal 

 sac. Last hearts in XIII. Hab. Tijibodas, Java. 



This species evidently, as HORST points out, comes very near to P. capensis, 

 The principal difference appears to be the length and coiling of the duct of the
