Pveliminary Notice of Victorian Eartlnvorms. 25 



(Jlitellum not strongl}' marked, occupj'ing segments 14—17, 

 and slightly darker than the surrounding parts. 



Setfe. The number and arrangement varies slightl}', hut 

 the following description of a particular specimen may be 

 taken as fairly repi'eseutative : — The first six setigerous 

 segments have lour on each side, an-anged in couples. The 

 seventh has four on one side and five on the other. T'he 

 eighth, four on each side ; and the ninth, four on one side 

 and six on the other. The tenth, six on each side. Tlie 

 eleventh, four on one side and six on the other. The twelfth, 

 four on one side and seven on the other. The thirteenth, 

 five on each side. The fourteenth, six on each side. The 

 lifteentli and sixteenth, five on one side and six on the other. 

 The seventeenth, .six on each side. The eighteenth, nine- 

 teenth, twentieth, twenty-fii-st, and twenty-second segments 

 have eight on each .side, except on the right of the twentieth, 

 wliere there are siw Behind this, the number varies from 

 (5-10 oii each si<le. Tiie two inner rows on eacli side are 

 regularly arranged, except during the posterior third of the 

 body. The doi'sal interval free from setpe is broad and 

 irregular. 



Male pores not on papilhie, at the level of the interval 

 between the two inner setse of each side, on segment IS. 



Oviduct pores on segment 14- anterior to, and slightly 

 ventral of, the level of the innermost seta3. 



Spermathecal pores, five pairs, between segments 4 and 5, 

 5 and 6, G and 7, 7 and 8, 8 and 9, at the level ot" the 

 innermost set*. 



Accessory copulatory structures. The whole of the ventral 

 surface of segments 16-21 is deeply depressed in spirit 

 specimens. Four pairs of small elliptical tumid patches are 

 [)resent, each at the level of the second seta. The first are 

 placed half on segment 16, half on segment 17, and the 

 remaining three respectively, half on segments 17 and 18, 

 1 9 and 20, 20 and 2 1 . 



i)or.sal pores present, the first between segments 4 and 5. 



Alimentaiy canal, Circulatoiy system. Excretory system 

 and Reproductive organs similar to those of P. yarraensis. 



This form is closely allied to the latter, but the presence 

 in F. yarraeihsis of 5 seta3 regularly arranged on each side in 

 front of the clitellum, renders it distinct and easy to recognise.
