618 NOTES ON AUSTRALIAN EARTHWORMS, 



two prostates occupy xviii and xix, each of them being a long 

 narrow body coiled into a compact mass, the duct coming off from 

 the anterior portion of the gland, (the junction with the vas 

 deferens not visible), the genital duct fairly long and U-shaped. 

 The ovaries and oviducts have the usual situation and relations ; 

 the spermathecpe are five pairs of stalked pouches opening ante- 

 riorly in segments v-ix, each with a short but distinct club-shaped 

 caecum only about ^ the length of the pouch. Ljing beside the 

 proximal portion of the genital duct is a small white body, its 

 distal extremity attached to the body wall by a ligament ; this is 

 a sac containing a thin curved penial seta. 



The segmental organs consist of small and delicate folded 

 tubules, a pair in each segment except a few anterior ones. 



The last pair of hearts in xil, this and the two preceding pairs 

 the largest. 



Hah. — Warragul, Gippsland, Victoria. 



This is the only Austi'alian species of the genus with five pairs 

 of spermathecse as yet described. The specimens were found in 

 rotten logs, and it was while searching for them that a specimen 

 of Peripatus Leuckartii, Sang., (antea p. 450) was picked up. 



PERICHiETA DORSALIS, n. sp. 



Three (spirit) specimens are 56, 88, and 95 mm. long respectively, 

 7, 6, and 5 mm. broad respectively, and comprise about 130 seg- 

 ments. 



Colour darker above and especially in the anterior portion of 

 the body, reddish-brown, lighter below. The prostomium divides 

 the buccal ring for slightly more than half. 



Setse for the first few setigerous segments 16 per seguient, then 

 increasing to 20, still further back and just in front of clitellum 

 24 may be counted, while in the posterior region there may be 

 about 30. There is a well-marked ventral interval devoid of set?e, 

 about twice (or a little less in front of girdle) the width of the
