Total length, 6mm.; height, 3mm.; height of neck, 1-75 mm. 

 Visceral hump Length, 4-5 mm. ; height, 2 mm. ; breadth, 2-5 mm. 

 Sole Breadth, 1-5 mm. (spirit specimen). 



Shell auriform, yellowish-horny, flexible, membranaceous, trans- 

 parent, with a notch on the right posterior side ; 1 whorl only, with 

 microscopic distant growth-lines. 



Length, 2-75 mm. ; breadth, 1-6 mm. 



Jaw arcuate, delicate, composed of 15 very thin vertical laminae, 

 all of which are separated from one another. 



Radula elongated, tongue-shaped, consisting of about 150 straight 

 transverse rows of teeth, the formula being 13+7+1 + 7+13. The 

 last marginal tooth is a minute plate with a rudimentary denticle ; in 

 the two following teeth the denticles still coalesce, but show beginning 

 division. The base of attachment in most of the marginals is much 

 broader than high. On the 17th tooth the division into distinct teeth 

 begins ; the ectocone is always smallest, sometimes bidentate, the 

 mesocone is the stoutest, and the entocone is more slender and slightly 

 directed towards the centre of the radula. A few quadrate transition 

 teeth occur between the marginal and lateral teeth, on which the 

 ectocone is minute, the mesocone large, reaching to the posterior 

 margin of the base, and the entocone about twice the size of the ecto- 

 cone. The laterals have a square base, higher than broad, and are 

 tricuspid. The mesodont reaches a little beyond the posterior margin 

 of the base, the side cusps are short and with minute cutting-points. 

 The central tooth is exactly like the mesial laterals. 



Type in my collection. 



Hob. Auckland Islands (Lady Constance Knox). During the 

 Subantarctic Expedition two specimens were found by Professor 

 W. B. Bentham, one at an altitude of 1,350 ft. 



Remarks. Ranfurly a stands in the same relation to Flammulina 

 as Schizoylossa does to Paryphanta. 



NOTE. 



Quite a number of foreign shells were sent by Mr. T. W. Kirk to 

 Captain Hutton, stating that they had been found in New Zealand, 

 and giving exact localities. Mr. Kirk made an error, and, as some 

 of them were described as new species, they will have to be expunged 

 from our fauna list. They are as follows : 



1. Amphidoxa Lavinia, Hutton, T. N.Z.I., xvi, 180, which is the 

 common Australian Rhytida capillacea, Fer. 



2. Vitrina Milligani, Pfr. (T. W. Kirk, T.N.Z.I., xii, 307). This 

 is (vrtainly not the rare Tasmanian .species, but Paryphanta urnula, 

 Pfr. 



3. Neritina ftuviatilis, L. (T. W. Kirk, T.N.Z.I., xiv, 268). The 

 specimens are correctly named, but they certainly do not belong to 

 the New Zealand fauna.
