The diNtiibution of the former species is in marked contrast 

 to that of most. Certain forms, such as P. tanjilensis and 

 yarraensis, are characteristic of the Upper Yarra Valley 

 especially. Perichcvta fielderi, a veiy well marked form, 

 has only come from Fern Ti-ec Gully and Sassafras Gully 

 and the hills outside Narre Wan-en, all of which localities 

 lie within a small compass. P. hakeri, copelandi, 'and 

 ohscura, are characteristic of the Warragul district in 

 Cippsland, and P. deiulyi is an intei'esting form recorded as 

 yet only from Healesville. P. lateralis has been found only 

 in North West Victoria and is closely allied to the Soutli 

 Australian species P. stirlingi.

Unless otherwise stated, the description alway?, refers to 

 spirit specimens. Such structures as the accessory copulatory 

 ones are only evident after preservation, and examination of 

 numerous specimens shows that spirit exerts a uniform 

 action upon these. 



(I) Perlchceta copelandi, sp. n. (Figs. 52, 53, 54, 76). Length 

 of spirit specimen o inclies, | inch broad. Number of 

 segments about 175, 



Dark purple colour dorsally, with a darker median line. 



Prostomium completely dovetailed into the peristomiuni, 

 and marked by a median groove. 



Clitellum not strongly marked, occupying segments 13-17, 

 but not alwa^^s the anterior part of 1.} or the posterior of 17. 



Setpe. The first setigerous segment has 10 on each side, 

 after this and to the posterior end of the clitellum the 

 number varies from lo-]7. Behind segment 20, it varies 

 from 23-25. On the last 6 or 7 segments the setae are 

 difficult to see. Dorsal and ventral median lines free of 

 seta3. 



Male poi'es on papillae in segment 18, at the level of the 

 interval between the two inner seta^ of each side. 



Oviduct pores on segment 14 anterior to, and at the level 

 of the interval between the two inner seta; of each side. 



Spermatl)ecal pores, 5 pairs placed on the line between 

 segments 4-9, very slightly dorsal of the level of the innei'- 

 most setse.
