 Diameter Maj., 3-75 mm. ; min.. 3-5 mm. : height. 2'75 mm. 

 (A. Miranda, Hutt.). 



Animal. Mantle subcentral ; tail truncated, with a mucous gland 

 below a papilla ; eye-peduncles thick, approximated at their bases. 

 .Anterior portion of the animal pale-purplish, the peduncles darker ; 

 a narrow white line down the back ; foot and the rest of the body 

 yellowish-white (for Miranda, Hutton. T. N.Z.I., xvi, 181). 



Dentition. Hutton, i.e., 181, pi. 9, f. W ; pi. 11, f. S. (Ch. Miranda). 



Jaw rudimentary, flatly plaited, the cutting-edge indented. 



Eadula having the formula, 9 + 8+1 + 8 + 9. Central tooth 

 rectangular, the base longer than broad ; the reflexed portion tri- 

 cuspid, the middle cusps covering three-fourths of the base. Laterals 

 with the reflexed portion larger, reaching the posterior margin of 

 the base, the inner side slightly indented, the outer with a well-marked 

 cusp ; median cusp with a long point. Marginals broader than long, 

 with 4 or 5 points, the inner of which is much longer than the others. 



Type of Helix granum, Pfr., was in the British Museum but seems 

 to be lost. Type of Charopa Miranda, Hutt., in the Canterbury 

 Museum, Christchurcb . 



Hob. North Island : Hunua Range (Major Broun) ; Mount 

 Pirongia (T. Urquhart) ; Toko, near Stratford (R. Murdoch) ; Wai- 

 marama (A. Hamilton) ; Forty-mile Bush (H. S.). South Island : 

 Greymouth (R. Helms) ; Nelson ; Capleston (Cavell) ; Bealey ; 

 Queenstown (Captain Hutton) ; Otarama (A. Suter) ; Kowai Bush 

 (Professor Chilton). 



Remarks. Although the type of Helix granum, Pfr.. is lost, and it 

 lias never been figured, I do not doubt its identity with Charopa 

 Miranda, Hutt. The diagnoses and dimensions of the two agree very 

 well, and I do not know another New Zealand shell that corresponds 

 so well with Pfeifier's species.
