from Hutton's marmoreus. The name bestowed on the species by 

 the late von Martens cannot stand, and I now propose the above name. 

 JSab. — Auckland Islands (Dr. Krone, Captains Hutton, Bollons, 

 and Professor Benham) ; Macquarie Island (Dr. Colquhoun).

 Janella papillata, Hutt. : Trans. N. Zeal. Inst., 1879, vol. xi, p. 332. 

 A. verrucosus (v. Mts.), Simroth : Suter, Proc. Mai. Soc, vol. ii, 

 p. 251 ; noil Simroth. 



There is no spermoviduct and no prostate, only the accessory bulbose 

 and glomerate glands. Beceptaculum serainis proximal. 



This species is very variable in colour, either uniformly olive or 

 dark coloured with the papillae of lighter colour, or yellowish with 

 rows of large brown spots. A. verrucosus is a very distinct species. 



Hcii. — North Island: Heretaunga and Forty Mile Bush. South 

 Island : Pelorus Valley, Nelson, Greymouth, Little River, Biccarton 

 Bush, Governor's Bay, Hooker Valley, Ashburton, and Invercargill. 

 Chatham Islands {fide Hutton).

 p. 141 ; Zool. Jahrb., Anat., vol. xi, pp. 193-269, pis. xii-xvi. 

 Very near A. papillatiis, but the head-shield without a median 

 groove ; the side-grooves less numerous, about fifteen against twenty ; 

 the lateral fields of notum with two to four papillae only, but about 

 six in A. papillatus ; the central tooth of the radula with three 

 denticles, and the receptaculum seminis distal. 



Hah. — Stephens Island, Cook Strait (Professor Schauinsland).

 A. Simrothi, Sut. : Proc. Mai. Soc, 1896, vol. ii, p. 34, pi. iv, 

 figs. 3, 4; p. 253. 

 No other specimen has turned up, and the anatomy still remains 

 unknown. Plate suggested that it might be a young specimen of 

 papillatus or Schaumslandi, but I cannot share this view. The large, 

 oval, crowded papillae distinguish it at once from all the other 

 hitherto known species of the genus. 



Subgen, 4. Amphiconophoea, Suter, 1897. 

 Amphikonophora, Suter: Proc. Mai. Soc, 1897, vol. ii, p, 256. Type, 

 A. gig aniens, Suter. 

 New Zealand slugs with dorsal, median, and lateral grooves ; mantle- 

 area distinct, triangular, with the renal orifice inside its anterior 

 angle, the pulmonary opening sub-central. Anus near the mantle- 

 area, sometimes inside it.

 Animal (spirit specimen) large, limaciform, broad in front and very 

 gradually tapering toward the broadly rounded tail ; back flatly convex,
