240 mm., 118 segments. Setae 48, 13 between male pores. 

 Male pores on xix. Papillae paired on xvii., xviii., xx. Spermi- 

 ducal glands large. Diverticulum of spermathecae long. 



Hab. Japan. 



This species is absolutely unique in the genus, by reason of the 

 fact that the male pores open on to the xixth segment. It may 

 be, of course, that in those species, such as A. hilgendorfi, in which 

 the position has not been ascertained, owing to the entire absence 

 of a terminal apparatus, it may also open on to that segment.

60-190 mm., 110 &c. segments. Anterior setae larger, 31 on v., 

 46 on xvi. ; they are ornamented. Papillae paired on vii.-ix., also 

 often two or three quite close to male pore. Spermiducal gland 

 often absent altogether. 



Hab. Everywhere, including Europe. 



I have already pointed out 2 that Perichceta indica figured by 

 Horst cannot be the same species as that to which the name of 

 P. indica has been also given by myself and others, since in the 

 former there is a large end-sac, through which the duct of the 

 spermiducal gland opens on to the exterior ; and I a<:ree with 

 Michaelsen in this identification. P. perhinsi is at most a variety of 

 the type examples. Pheretima californica (see p. 627) of Kiuberg 

 is partly identical. Perichceta modigliani of Rosa must also be 

 included, since it appears to have the same papillae near to the 

 male pores. P. nipponica has numerous or few secondary diver- 

 ticula to the spermathecal appendix, apparently resembling 

 P. darnleiensis in this. As I only have one specimen of the 

 former, I (in the meantime at least) follow Michaelsen in in- 

 cluding it among the synonyms of A. heterochcetus.
