 between male pores. Dorsal pores from vi. Spermiducal glands 

 xv.-xxiv., much broken up. Diverticulum of spermathecae very 

 long and often coiled like a sbeep's horns.

The above list of synonyms is largely in accordance with 

 Dr. Michaelsen's views. I do not, however, follow him in 

 including Benham's Perichceta ivilleyi, since that species has no 

 terminal sac to the duct of the spermiducal gland. I am also of 

 opinion that Eosa's species P. fasciata is not rightly included, as 

 the describer says nothing about a sac. In any case, it cannot be 

 doubted that the worms here included in one species are at least 

 exceedingly near to each other in structure. The peculiar ram's- 

 horn appearance of the long diverticulum of the spermathecaj is 

 not apparent in all the individuals, to judge from the published 

 illustrations. But that is very possibly a matter of contraction. 

 It should be observed that it is not clear from Eosa's description 

 that his operculata has a terminal muscular sac. Nor does Ude 

 mention this structure in identifying operculata with capensis. 

 Eosa, indeed, says the duct of the spermiducal gland " f iihrt direct 

 nach aussen." But the sac looks as if it had been extruded in his 

 specimen.

"Were it not for the fact that the setae are absent in this species 

 from segment x., it would be impossible to avoid placing it with 

 that which has just been described.
