The specimen is smaller than the type, being only 55 mm. 

 x 2 mm. 



It was collected in " bog land, in peat of Pleurophyllum." 

 This " Pleurophyllum meadow " is described in detail by Dr. Cock- 

 ayne in his interesting article " A Botanical Excursion during 

 Midwinter to the Southern Islands of New Zealand"*: "Then 

 the leaves of the past year lie rotting upon the surface of the 

 soil, while their bases form great decayed masses many centi- 

 meters in thickness round the leaf-bases of the young leaves 

 of Pleurophyllum criniferum or P. hookeri. In these sheaths of 

 decaying leaves considerable numbers of earthworms were found, 

 and they appear also to be fairly numerous in the peat itself." 



Those from the Campbell Islands were obtained from the 

 " roots of plants " in some number, mature and immature. 

 Their colour is pinkish-brown anteriorly, instead of sienna-brown 

 as in the type. The only noticeable difference anatomically from 

 the type is the absence of definite oesophageal glands, though the 

 gut-wall is thicker and dilated in segments 13, 14, and 15. Also 

 the diverticula of the spermathecae arise from the duct free from 

 the body- wall. 



From Adam Island (one of the Lord Auckland Group) I 

 received nine specimens, of which three are immature. These 

 show no sensible variation in colour. 



Notiodrilus campbellianus, n. sp. 



Three specimens were obtained, of which two are immature ; 

 all are ill-preserved. 



Colour (in formaline). — Dark chocolate-brown, with paler 

 clitellum. 



Length, 50 mm., approaching N. macquariensis. 



Prostomium is epilobic, one-third, with a transverse groove. 



The chajta? are isolated, the interspaces nearly equal, though 

 the gap be ( = aa) is greater than ab or cd, and dd is considerably 

 greater than aa. This chsetal formula agrees with that of N. 

 macquariensis. 



The clitellum is complete, extending over segments 13 to 16 

 in the only mature specimen in my possession. 



Genital Pores, &c. — The porophores are white, in line with b. 

 There are also paired copulatory tubercles, quite pale in colour, 

 near the anterior margins of segments 17. 19, and 20, in line 

 with a ; while behind the spermathecal pores in segments 8 and 9 

 similar tubercles occur in the same line. This, in general, agrees 

 with w hat 1 bave recorded for N. aucUandicus, for in .V. macquari- 

 ensis no ment ion has been made of such tubercles. 



Intermit Amtlomy. -The dorsal vessel is single, and the last
