aAKTHWORMS FROM NEW ZEALAND.

The three paii-s of speruiatJiecal pores are in line «, at 6/7, 

 7/8, 8/9. 



Internal Anatomy. 



There are five slightly tliickened septa, behind segments 8 

 to 12. 



The last heai-t is in segment 12. 



The gizzard es feebly developed ; its wall is not tliicker, though 

 tougher, than that of the cesophagus. 



The prostates are quite typical, and extend back to segment 

 23, with tips recurved ; the duct is short and narrow. 



The spermatheca (text-fig. 77) has a long duct, with a. long- 

 narrow diverticulum opening into it at the body-wall. 



Locality. Auckland, New Zealand. 



Remarks. — Anatomically thei-e is a rather close resemblance 

 between this and the two preceding species ; but in the coloration 

 and dimensions it is remarkably distinct, while the practical 

 equidistance of all the 8 chaBtte, the paired tuhercula piibertatis, 

 and the details as to the pi-ostate and septa, mark it o& as 

 distinct. 



6. ToKEA KiRKi, sp. n. (Text-figs. 78, 79.) 



Five specimens collected by Professor H. B. Kirk, in 1902, are 

 about the same size and colour as T. esculenta, i. e. reddish purple, 

 but rather paler than the latter.; the pigment extends further 

 I'ound to the ventral surface tlnan is usually the case, and ceases 

 abovit the level of b. 



The clitellum is brownish red.

Text-fig. 78. Tokea Jcirkl, similar view to that in text-fig. 62. ( X 7.) 

 Text-fig. 79. ToTcea kirJci. — Spermatheca ( X 12. Camera outline of mounted 

 specimen). This has no muscular duct distinct from the sac. 



Dimensions. The length varies from 80 to 100 mm., with a 

 diameter of 6 mm. for 110 segments in the larger individuals. 



The chcetce are practically equidistant ; but on measurement it 

 is found that ab-=hc — cd ( = 1-75 mm.), while aa = cld-=2 mm.
