The shell is of a more or less oblong- fusiform shape, 

 being attenuated at both extremities, though more acu- 

 minately so above, where it tapers to a fine point ; it 

 varies as to length, the body being sometimes much more 

 swollen than in ordinary, in which case the usually pro- 

 duced spire is less elongated. It is strong for its size, and 

 of an uniform tint of coloui", either rufous or dark reddish 

 brown, which changes in the large dead or very aged 

 examples into reddish yellow. There are no true varices, 

 but the principal whorls are longitudinally traversed 

 throughout by broad prominent shelving rounded ribs, 

 that are least raised beneath the sutures and at the 

 anterior extremity. The intervals of these ribs, of which 

 there are usually about eight upon the body-whorl, are 

 about equally broad, and both alike are ridged by dense 

 spiral costellai, that are sometimes smooth and rounded.
