tributed. It is also densely distributed, since there are no 

 less than three localities in Natal — Howick, Pietermaritzburg, 

 Durban. The worm was doubtless introduced in earlier times 

 and has spread widely. Various statements have been made 

 of a F rider icia being found on various islands associated 

 with Africa — Zanzibar, St. Paul, New Amsterdam, St. Helena. 

 In all these cases the worm referred to is a species of the 

 small "bisetose^' group of this genus. In my opinion all 

 these worms are Fridericia peregrinabunda; but since 

 the specimens from these islands were immature it is not 

 possible to be absolutely sure.
