34 PROCEEDINGS OF THE MALACOLOGICAL SOCIETY, 

Named in honour of Prof. Dr. Th. Studer, Berne, Switzerland. 
The only specimen I possess 1s immature, so that the generic — 
position is somewhat doubtful. 
3. ArHoRAcopHoRUS (PsEUDANEITEA) Srwrorut, n.sp. PI. IV, 
Figs. 3, 4. 
Animal (in spirit) elongate, about five times longer than broad 
fulvous; head broadly rounded, tail tapering; back rounded. 
presenting a botryoidal appearance owing to the numerous strongly 
developed papille; it is separated from the foot by a broad lateral ’ 
groove, keeled towards the sole, which is lighter-coloured; dorgo- 
median groove, bifurcating towards the head, distinct, extending to 
the tail. There are about twenty lateral grooves on each side, and 
a lateral area contains two to three rather large papille. These 
papille are oval, 1 X 1-5mm., on the central part of the body, and 
about -75 to 1mm. high; the interstices between are granulate, — 
The mantle-area, which I cannot make out distinctly in the 
specimen before me, seems to be triangular, the pulmonary orifice 
being situated at its anterior angle. The lateral grooves, the keel, 
and the sole are crossed by numerous transverse furrows. Length 80, 
breadth 2, height 5mm. (alcoholic specimen). 
Type in my collection. 
Hab.—Collingwood, South Island (Mr. J. Dall). 
Named in honour of Dr. H. Simroth, of Leipzig. 
This slug is so distinct and peculiar in its appearance that I will 
not defer its preliminary description any longer. I have only one 
specimen, and that in a rather bad state of preservation, since the 
animal was probably placed alive in strong alcohol. ‘The diagnosis 
and the sketches I give must be considered as merely provisional. 
I hope to get some living specimens later on, when the description 
will be completed, better figures given, and the anatomy investigated. 
I do not doubt that this species must be assigned to the subgenus 
Pseudaneitea, since it possesses the main characters of Athoracophorus | 
papillatus, Hutton. | 
The New Zealand species of Athoracophorus now known to science | 
are :— | 
. bitentaculatus, Q. and G. | 
. maculatus, Collinge. | 
- (KKonophora) marmoreus, Hutt. 
. (Pseudaneitea) papillatus, Hutt. 
- (Pseudaneitea) papillatus v. nigricans (v. Mts. MS.), Simroth. 
- (Pseudaneitea) papillatus v. fasciatus (v. Mts. MS.), Simroth. |

4. Enpoponta (Cuaropa) Rosrvearr, n.sp. Pl. IV, Figs. 5-7. 
Shell small, subdiscoidal, umbilicated, horny, with radiate rufous 
streaks which are irregularly disposed on the upper surface, form 
“1gzag lines on the periphery, and are obscurely tessellated on the 
base; dull, thin, semi-transparent. Spire flatly depressed ; periphery
