" This species is described from two specimens in my collection 

 One is evidently full-grown, except that the lip is not expanded ; 

 this specimen lias its green epidermis in fine condition. The other 

 specimen is perfect in form, but rather worn, and only shows traces 

 of the epidermis. It chiefly differs from Mouhoti in its dark brown 

 lip and columella, its longer form, and in not being subangulate at 

 tin- periphery. Named after Mr. Edgar A. Smith, of the British 

 Museum " (Fulton). 



Var. ventrosulus Mollendorff. 



Fruhstorfer collected a magnificent Amphidromus at Phuc-son, 

 Annam, which agrees very well with Fulton's description ; but he 

 does not mention that the apex, about 3 whorls, is brownish-red. 

 The fourth whorl shows brown, partly zigzag, spots, at the suture, 

 but no second row of them. The lip and columella are not dark 

 brown, but red-brown or violet-brown. The contour is stouter, 

 diam. 2U, alt. 40, to 25, 48 mm. (MlMff., Nachrbl. 1900, p. 132).

 straw colored, washed with pale green at the base, the apical two 

 whorls roseate, the third dotted with reddish-brown. Whorls 6^ to 

 7, a little convex, the last swollen, obtusely angular, delicately costu- 

 late on the back, a little shorter than the spire ; suture marked with 

 an orange line. Columella vertical or slightly receding. Aperture 

 oblong, angular below, white within ; peristome well expanded, 

 deeply stained with carmine outwardly, purple inwardly, the margins 

 joined by a thin purple callus, columellar margin dilated. Length 

 33, diam. 15, aperture 16 mill. (Morel.). Cambodia.

The purple peristome is a characteristic feature of this species.
