 in fome a few diffant tranfverfe flria^, nearly obfolete, are 

 obferveable; but no longitudinal ones: umbo placed near- 

 eff to one end: teeth fmall, efpecially the lateral ones. 

 Infide purple, margin quite fmooth. Length five-eighths 

 of an inch; breadth an inch and a quarter. 



This elegant fpecies has much the habit of the Truncu-
