Benson, in describing the species, states that " independently 

 of size, colour and greater solidity, there would be little to 

 distinguish this shell from the true H. similaris, Fer., were it 

 not for its peculiar sculpture." The comparison, to my mind, 

 is not a happy one as scalpturita, apart from its sculpture, has a 

 totally different contour. Benson also refers to a still more- 

 depressed, and smaller, variety than that of which the measure- 

 ment is given, found by Mr. Theobald at Thyet Myo or Prome, 

 but he gives no dimensions. I possess some specimens from Ava 

 which measure : diam. maj. 18'5, min. 16*5, axis 10 mm. On 

 the other hand, the British Museum contains specimens, from 

 the Upper Irrawaddy, measuring : 28 : 24 : 22 mm., and some 

 shells from Pegu without the peripheral band.
