 This valuable and elegant shell is about an inch and a half, or 

 sometimes two inches and a half long, and the breadth is 

 about three-fifdis of the length ; it has eight sub-cylindrical 

 •whirls, which, without being attached to each *'ier, are 

 connected only by much elevated somewhat membranaceous 

 longitudinal ribs, and of these there are about eight on the 

 body-whirl; the aperture is marginated ; it is generally of a 

 snowy white or sometimes pale flesh-colour. Gualter and 

 Favanne have placed it among the Serpulae, and Dr. Leach 

 has separated it from Lamarck's genus Scalaria, on account 

 of its want of a pillar. Large and perfect specimens for- 

 merly sold at very high prices, and one which now belongs 

 to Mr. Bullock has been valued at two hundred guineas. 

 Da Costa, in his Elements of Conchology, relates that in 

 1753, at the sale of Commodore Lisle's collection, four of 

 these TVentletraps were sold as follows :
