34 PROCEEDINGS OF THE MALACOI.OfilCAL SOCIETT. 



Named in honour of Prof. Dr. Th. Studer, Berne, Switzerland, 

 The only specimen 1 possess is immature, so that the generic 

 position is somewhat doubtful. 



3. AtHOEACOPHORUS (PsEUDANErTEA) SiMEOTHI, 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 tlie numerous strongly 

 developed papilhie ; it is separated from the foot by a broad lateral 

 groove, keeled towards the sole, which is lighter-coloured ; dorso- 

 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 papillae. These 

 ixxpillae are oval, 1 x 1*5 mm., on the central part of the body, and 

 about -75 to 1 mm. 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 30, 

 breadth 2, height 5 mm. (alcoholic specimen). 



Type in my collection. 



7/rt^.— Collingwood, South Island (Mr. J. Ball). 



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 preliminaiy 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.

 are : — 



A. hitentandatus, Q. and G. 



A. maculaius, Collinge.

4. Endodonta (CnAROPA) RosEVEAKi, n.sp. PI. lY, Figs. 5-7. 



Shell small, subdiscoidal, umbilicated, horny, with radiate rufous 

 streaks which are irregularly disposed on the upper surface, form 

 zigzag lines on the periphery, and are obscurely tessellated on the 

 base ; dull, thin, semi-transparent. Spire flatly depressed ; periphery
