176 Godwin- Austen — On the Operculated Landshells [No. 3, 



a large series. It has yet to be decided what points are to be considered 

 of sufficient weight in separating these forms from one another. We 

 must wait until the whole area has been worked, and the points of 

 difference, however small, all noted, when we shall then be in a position 

 to reduce species or to arrange slightly divergent forms around their 

 nearest and most abundant and widely spread ally. As far as my 

 experience goes, they never remain constant over very large areas. 

 Hab. — The above shell was obtained on the slopes of Toruputii. 



ALYaams Bttrtii, G-A. 



Hab. — This shell, of which I previously possessed a single specimen 

 only, found by Mr. J. Burt in the gorge of the Barowli river a short 

 distance to the west, proved to be abundant on the outer sandstone range 

 about Dihiri Parbat, the Burroi gorge, &c. 



A variety of it, which is much larger and more depressed in form, but 

 which in the crenate peristome and in form of constriction is the same, 

 occurred in the valley of the Dikrang and in the Yetay ravine. This 

 variety measures in alt. 018, major diam. 0"25. in. 



Altc^ius notattts, n. sp., PL VII, Figs. 9, 9a, & 95. 



Shell globosely turbinate, narrowly umbilicated, of solid form, white, 

 distant strong costulation on the upper whorls, close and fine ribbing on 

 swollen portion of the last. Spire conoid, suture fairly impressed. Whorls 

 4 \, closely wound, the last swollen, then sharply constricted, and again 

 enlarged and descending, the expanded portion being marked with deep 

 fold-like furrows. Sutural tube moderate, aperture oblique. Peristome 

 very thick, distinctly treble in full-grown shells, outer layer terminating 

 just behind the aperture, the inner continuous, the two outer much reflected 

 near the umbilicus. Operculum smooth in front. 



Alt. 0"14, major diam. 0'17. in. 



Hab. — On the slopes of Toruputii Peak at 3000 feet, about 15 speci- 

 mens collected. 



This is one of the most distinct and ciu*ious species I have yet dis- 

 covered, the fold-like indentations upon the expanded portion near the 

 aperture having no counterpart in any other form with which I am acquaint- 

 ed. In other respects it is somewhat similar to A. diagonius, in the strong 

 thick peristome and closely wound whorls.

Shell turbinate, moderately umbilicated, pale whitish or dull ochreous 

 according to the state of the epidermis, finely ribbed throughout, rather more 

 coarsely near the commencement of the swell of the last whorl, on this por-
