shelly, and thin. The animal has large leaf-like right and left 

 shell-lobes, which ia life nearly cover the whole of the shell. 

 In the genitalia the penis has a coiled caecum near the retractor 

 muscle, and is thus similar to Macroclilamys.

Shell depressed, thin, pellucid, very faintly striated, smooth, 

 polished, yellowish horny ; spire flat, apex very slightly prominent, 

 suture impressed ; whorls 4, rapidly increasing, flattened above, 

 the last not descending, rounded at periphery, moderately tumid 

 beneath, flattened towards mouth ; apertiu-e oblique, ovately 

 lunate ; peristome thin, margins converging, the upper straight 

 near the last whorl, then arcuate near right margin, columellar 

 sinuate, forming a rounded obtuse angle with basal margin.

The animal (of A. scutella from Murree) [which I consider 

 distinct from monticola of Mussoorie] has well-developed dorsal 

 and shell-lobes to the mantle, [and these are quite plain and 

 unmottledj. The posterior portion of the foot is very long and 

 sharplv keeled above. The odontophore bears the following teeth : 

 30 . 2 " 14 . 1 . 14 . 2 . 30 (46 . 1 . 46). 



Pfeiifer described this shell from one of three specimens, 

 all smooth, translucent, and depressed shells, still in the British 

 Museum. Reeve figured a much more globose form, also in the 

 Museum, with a raised spire and different sculpture (apparently 

 E. cassida, Bs.). Hanley again figured apparently the same 

 species, and Godwin-Austen, misled by Hutton, as pointed out 

 by Nevill, has done the same. Theobald also recognized the true 

 monticola, which he had received from Benson. Scutella w-as 

 named from two different shells, one from Kashmir (Nasmana on 

 the Chandrabhaga liiver), the other said to be from Teria Ghat in 

 the Khasi Hills. The last is an obscure form not recognized 

 since. The Kashmir form differs slightly from E. monticola in 

 having its mouth even more lengthened, but it is doubtful whether 

 this is constant. I regard the two as identical.
