12 A MONOGRAPH OF 



13. — Helix ( ) Savesi. N. Sp. 



Shell umbilicated, depressed, very tliin ; shining, horny-yellow> 

 occasionally almost white ; prominently, obliquely ribbed throughout, 

 ribs occasionally somewhat moniliform ; interstices with fine striae and 

 decussate, the latter more perceptible on the upper whorls than in the 

 last ; spire flattened, small, apex projecting , whorls 5| to 6, flatly- 

 convex ; suture impressed, very rapidly increasing in size, last large, 

 not descending in front ; jDcriphery rounded ; base sculptured as above, 

 but becoming finer as it approaches and enters the umbilicus, which is 

 moderately open and funnel shaped ; aperture diagonal, ovately-lunar ; 

 peristome simple, thin, margins approximating and joined by a thin, 

 shining, smooth callus ; columellar margin a little dilated. 



Diameter, gi-eatest 11, least 9; height, 5 mil. 



Habitat. — Table Cape. 



I collected this species in the dense forest at Table Cape with H. 

 Wynyardensis, from which it differs in its paler colour, coarse sculpture, 

 height, and thin texture. It may be but an extreme variation of H. 

 Stephensi, but the characters enumerated in the diagnosis are invariably 

 constant, and seem sufficient to apply a name to the shell. 



Described from a specimen in the collection of, and kindly lent to me 

 by Mr. J. Brazier, to whom I am much indebted for assistance in col- 

 lecting material for this paper. Named at Mr. Brazier's request after 

 M. Saves, a French collector. 



14. — Helix ( ) Kingi — Brazier. 



Brazier, Pro. Zool. Soc, 1870. 

 Legrand, Col. for Mon., species 52. 



Shell umbilicated, convexly depressed, rather thin ; very closely and 

 irregularly finely striated and decussate ; not shining, brown, horny ; 

 spire conoidly-convex, obtuse at the apex, impressed at the suture ; 

 whorls 5|^, slightly convex, last large, depressed in front, somewhat angled 

 at the periphery, base rounded and marked with decussating striae ; 

 ■umbilicus deep, sub -compressed ; aperture slightly oblique, huiately- 

 oval ; peristome simj^le, margins approximating, columellar margin 

 expanded and reflected. 



Diameter, greatest 0'37, least 0*29 ; height, 0"30 of an inch. 



Habitat. — Bingarooma, Ben Lomond, Biver Leven, Circular Head, 

 Emu Bay. 



Specimens that I have collected at the Biver Leven are at least three 

 times as large as the type from Bingarooma, but the same in every other 

 respect. It apj)roaches H. Haniiltoni (Cox), but may be known by its 

 battered-like, rough look, the height of spire, and the form of the aper- 

 ture. It is not at all abundant, and is as often found in dry open places 

 as in the dense moist forest.
