1002 NOTES ON AUSTRALIAN EARTHWORMS, 



in IX and xii (fee. ; but in the specimen dissected the c?eca of the 

 spermathecge not so long (possibly only due to its non-breeding 

 condition) ; and penial set^ only slightly curved but sharply bent 

 almost at a right angle close to the free extremity are present. 

 Last pair of hearts in xiii. 



Hah. — Dubbo, N.S.W. ; from the banks of the Macquarie 

 River (collected by Mr. C. E. Rennie). 



Allied to P. austrina and P. hainiltoni, but distinguished from 

 them by the slightly more ventrally situated spermathecal pores, 

 by details in the number of seta*, by the possession of penial 

 setse, and of a pair of hearts in xiii, and other details. 



PeRICH^TA (?) TERRiE-REGIN^, n.Sp. 



One specimen rather contracted except in the middle region of 

 the body which is soft and relaxed, 190 mm. long, 15-18 mm. 

 broad ; number of segments 144. Body stout, cylindrical ; seg- 

 ments iii-xiii biannulate, but with the anterior annulus in some 

 of them faintly again subdivided ; behind xiii there is little indi- 

 cation of annuli, nor are setiferous ridges anywhere prominent. 

 Colour dark, probably purplish (the specimen both somewhat 

 bleached and stained). Prostomium but slightly divides the buccal 

 ring (about J). 



Setae : from their retraction, worn condition, or absexice, it is 

 difficult to determine the number of the setse on the first few and 

 the last few setigerous segments ', elsewhere one may count from 

 about 40-60 to a segment, with a median dorsal and ventral 

 interval devoid of setse of which the latter is fairly defined, its 

 limiting rows of setae straight, about five times the breadth of an 

 ordinary interval between two set?e on the ventral and lateral 

 surfaces where they are closer together, more regular, and not so 

 frequently missing as on the dorsum ; the latter much broader, 

 ill-defined owing to the absence or irregularity of the setse. 



Clitellum not developed, but segments xiv-xxi, and xiii 

 and xxii slightly, are of a noticeably different colour^ a brighter
