 land shells from the Nilgiri and Anamullay Hills, and other places 

 in the Peninsula of India. — By W. T. Blanford, A. R. S. M.,

[Received 3rd February, 1866.] 

 Of the shells described in the following pages, the greater portion 

 were collected by Captain Beddome, Deputy Conservator of Forests, 

 in the Madras Presidency. This is the case with all the shells from 

 the Anamullay hills, and also the remarkable species of Spiraculum 

 from the neighbourhood of Vizagapatam. The Nilgiri Hill shells 

 were found by myself in a recent visit, and II. intumescens was given 

 to me some years since by Mr. Theobald as II. Bajadera, Pfr. 



1 have since collected the shell myself living at Mahableshwar.

 solid, white with transverse chesnut zigzag stripes. Spire flat or sub- 

 convex, suture deep. Whorls 5, rounded, the last cylindrical, de- 

 scending gradually towards the aperture, and furnished, 7-10 milleme- 

 tres behind the peristome, with a short open sutural tube, projecting 

 forwards and upwards, not touching the penultimate whorl. Aperture 

 diagonal, circular, peristome double, both lips continuous, the inner 

 slightly expanded, curved back into a shallow angular sinus at the 

 suture, the outer expanded, and inverted upon the upper and dextral 

 margins, rising near the suture into a compressed wing, which is at- 

 tached throughout on the left side to the penultimate whorl. Opercu- 

 lum horny, concave within, convex without, flattened near the centre,
