chgetaa * ; each is a deep cresceutic pit, with overhanging outer 

 rounded lip (somewliat as in P. capensis and P. operculata). 

 This carries a small cup-shaped papilla. From the bottom 

 of the pit I can see a rounded tubercle projecting — the duct, 

 no doubt, of the spermiducal gland. It is indicated on the 

 left side of the figure. 



Further, between the male pores on xviii., in front of 

 chastge, are two other cupped papillae {" suckers "). 



The oviducal pore is median. 



There is a single pair of spennathecal pores between segments 

 vii./viii., which, however, are not recognizable externally. 



The clitellum presents no chgetse and occupies the normal 

 position. 



The first dorsal pore is xii./xiii. 



There is no gap in the circle of chcetce^ which are rather 



closer together ventrally, and number 



On segment ii. 38.

Internal Anatomy. — There is only a single pair of spenna- 

 tJiecoi in segment viii. ; the sac is characteristically shaped, 

 being oval, but with the narrowed free end somewhat con- 

 stricted oflf. The duct is fairly long; the diverticulum, not 

 so long as the sac, is dilated distally and curved ; its duct is 

 slightly zigzag (fig. 4 d). 



The sperm-sacs are large and rounded, in the usual seg- 

 ments. 



The spermiducal gland is large and occupies three segments 

 — xvi., xvii., xviii. It is roughly divided into two main 

 lobes : one in xvi. and xvii. is nearly square ; the other in 

 xviii. is partially concealed by the duct ; each lobe is incised, 

 though not to a great extent (fig. 4 c). The duct is strongly 

 curved after leaving the gland, rises up vertically, and then 

 proceeds almost directly to the body-wall ; there is no " mus- 

 cular sac." 



In the normal position, when first opened, the duct extended 

 laterally beyond the outer margin of the gland ; in the figure 

 it is represented as having been lifted up. 



The ccecumj arising in segment xxvii., runs through xxvi. 

 into XXV. ; it is simple and not notched. 



The diagnosis of the species is as follows : — 



Alternate dark purple intersegmental and yellowish-white 

 broad chaetal bands; measures 200x6 millim. ; 120 



* The lithographer has, in error, put 11 in the fi^. 4 6.
