through this region of the body show that the two sperm-ducts 

 run back separately along the body- wall as far as the 18th 

 segment, w^hen, meeting the prostate duct, they pass on to its 

 dorsal surface into the 19th segment, and after vmiting with one 

 another open into the canal of the prostate gland some distance 

 from the commencement of the muscular duct (text-fig. 66). 



The prostate is traversed by a canal lined with columnar cells ; 

 at intervals this canal receives small canalicules, around which 

 the gland-cells are grouped and into which they open. The 

 arrangement is similar to that described by Miss Sweet for 

 Flutelhcs intermeclhts (loc. cit. fig. 17). 



There are no penial chsetse. 



There are three pairs of spermathecfe in segments 7, 8, and 9 ; 

 each (text- fig. 67) is an ovoid sac passing gradually into a short 

 wide duct, which receives the diverticvilum close to the body-wall. 

 The diverticulum is a short ovoid body, with duct ; it is about 

 ^ the length of the main sac. 



The diverticulum of this and the following species is placed 

 mediad of the sac. 



2. ToKEA SAPiDA, sp. n. (Text-figs. 68 & 69.) 



This species is founded on a single specimen of about twice the 

 size of the former species, but included with it as " Kurekure " 

 by Mr. Best.

 Text-fig. 69. Tokea sapida. — Spermatlieca ( X 12. Camera outline of mounted 

 specimen). 



In colour it is purple-red, with an imperfectly developed 

 clitellum of a deeper red than the rest of the body. 



Dimensions. 200 X 8 mm., with 190 segments. The pre- 

 clitellar segments are biannulate.
