H. VERRUCOSUS, Godwin-Austen. PL 43, fig. 55. 



" The shell with animal was placed in spirit, but has been 

 unfortunately lost ; it was thin and glassy, with about 4 whorls. 

 I however made a careful drawing of the animal at the time it 

 was taken." Animal dull purplish gray; mantle-lobes, which 

 can cover the entire shell, are very minutely mottled, finely 

 papillate ; posterior margin with three wart-like processes on 

 each side; posterior part of foot with diagonal parallel ribs; 

 edge of foot with a distinct marginal line. The mantle is divided 

 into three lobes, one of rectangular outline is on the anterior 

 left margin. The shell when the animal is in motion is very 

 slightly exposed. 



Under Toruputu Peak, at 4600 feet, Assam.

 tened above, rounded below, the last enlarging rapidly, trans- 

 verse. Diam. 13, alt. 6 mill.
