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. si^nihnis, 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 moi'e- 

 depressed, and smaller, variety than tliat of m hich 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, measui'ing : — 28 : 24 : 22 mm., and some 

 shells from Pegu without the peripheral band.
