characterized and P. pectenifera must, accordingly, be allowed to stand 

 until after reexamination of the Japanese types or amplification of 

 the original description. Further information is needed with regard to 

 size, spermathecal pores, setal numbers, septa 8/9-9/10, intestinal 

 caeca, testis sacs, and the preclitellar genital markings. 



Pheretima yamadai Chen, 1933, is almost certainly a composite of 

 two distinct species, P. pectenifera and P. tschiliensis Michaelsen,

 P. pectenifera. At least four of the Hamburg specimens labelled 

 "P. pingi" are obviously P. pectenifera.

PHERETIMA POMELLA, n. sp.

 Spermathecal pores minute and superficial, two pairs, presetal on vii
