Hab.—South Island: Dunedin; Greymouth ; Pelorus Valley. 
This is one of our rare species. 
Cockerell’s A. marmoreus, forma nov., from Dunedin,’ is undoubtedly 
A. papillatus var. fasciata. ‘‘ Depressed raised tubercles” are not met 
with in Aonophora. 
Subgen. AMPHIKONOPHORA, 0. subg. 
Large slugs with well-marked dorsal grooves. Mantle-area distinct, 
triangular, with the renal opening inside its anterior angle and the 
pulmonary orifice subcentral, nearer the right side. Anus close to the 
outer angle of mantle-area. The whole back finely granulate. 
This is no doubt the most interesting group of Athoracophorus. It 
is unique in the situation of the anus close to the mantle-area, 
approaching thus the genus <Anetea, from which, however, it is 
distinct, especially in the absence of a diverticulum on the crop, the 
presence of a renal duct, the form of the teeth of the radula, ete.

It is not very long since I obtained a specimen of this rare slug, 
which agrees perfectly with the description and figures published by

mantle-area, so characteristic of the species, is illustrated. Dr. Simroth’s 
specimen was a very small one, 20 mm., but it may well be that these 
slugs do not attain a much larger size on the Auckland Islands. The
