captivity several times, but they would never touch a fern. The 
favourite hiding-place of Athoracophoride in New Zealand is beneath 
and within rotten logs and in the leaf-sheaths of Phormium, at the 
pase of which plant there is always a large amount of moist, decaying 
vegetable matter. Examining the contents of the crop of 4. papillatus 
found under a rotten log, I found it to consist of a pulp of the rotten 
wood. I never saw these molluscs feeding, since they are nocturnal, 
but I do not doubt that the majority of these slugs live on decaying 
vegetable matter, with which fungi, ete., are always largely mixed. 
Hab.—North Island: Forty Mile Bush, small specimens only. 
South Island: Dunedin, Ashburton, Riccarton Bush, Pelorus Valley. 
Chatham Islands. Auckland Islands (Krone). 
Var. nigricans, Martens, 1889. 
Simroth, Nova Acta, ete., Bd. liv, p. 77. 
This variety seems to be very rare. The original locality is Auck- 
land Islands, but I have specimens from Dunedin and Pelorus Valley, 
South Island.

Simroth, t.c., p. 79. 
This is a more common form, which, however, I have not seen from 
the North Island. The arrangement of the dark-brown or black spots 
on the back is very variable, but usually they form three bands. It is 
sometimes as large as the typical form, but generally smaller. 
Hab,—Auekland Islands; South Island; Dunedin; Hooker Valley ; 
Pelorus Valley.

I have been unable to procure any more specimens of this interesting 
slug, and hence cannot add anything by way of supplement to my 
first communication. 
6. ATHoRrAcoPHoRUS DeENDYI, n.sp. 
Body (Figs. XII, XIIL) broadly elongate, anterior part very broad, 
‘Darrowing gradually towards the tail. Back flatly rounded, with 
median and lateral grooves deep and conspicuous, median groove ex- 
tending to the head, lateral grooves with one or two additional grooves 
near the margin. Colour dark-grey, darker along the middle. The 
Whole of the back minutely granulate, between the oblique grooves one 
or two large raised round tubercles of much lighter colour, forming 
@ single row on each side from the mantle-area to the head, double 
from the mantle-area to a short distance from the tail. Mantle-area 
triangular, sometimes quadrangular, granulose ; the pulmonary orifice
