OriyinaJ description : — " Testa perforata, subglobosa, tenui, 

 virescente-cornea, trauslucente, subtus niticliori, radiato-striata, 

 striis concentris delicatissimis decussantibus ; spira elata conoidea, 

 apice obtuso ; anfractibus 4 convexis, ultimo obtuse augulato ; 

 apertura obliqua, subquadrato-rotundata ; peristomate recto 

 (acuto), margiiie columellari verticaliter descendente, supra late

The Benson collection at Cambridge contains a tablet with 

 six specimens, the largest of which measures : diam. 11*5, 

 alt. 10"75 mm., the smaller ones being immature. No locality 

 is recorded on the tablet and it is rather doubtful whether the 

 type is one of them. A specimen in the Theobald collection of 

 the British Museum, from Simla, is likewise not quite mature, 

 the peristome not being quite developed. It measures: 11 : 9 : 

 11 mm.

Dr. Thiele, the Director of the Konigl.-Zool. Museum, Berlin, 

 has obligingly sent me the type of von Mai'ten's Helix elatior for 

 inspection, and a careful examination has convinced me that it can 

 at the most be only regarded as a variety of E. radicicola. It is 

 certainly a larger and more solid shell than typical radicicola, the 

 peristome is distinctly thickened and expanded, but scarcely 

 reflexed, while the columellar margin is broadly dilated and 

 refiexed, almost completely closing the umbilicus, a mere slit 

 being left, scarcely large enough to admit a very fine needle. On 

 some of the whorls very minute spirals can be detected with a
