 Stimpson. " Red Sea ;" label of sjtecimen, from G. B. Sowerby, in Coll. A. N. S. 

 The tube of this species is a well known object in Conchological Collect- 

 tions ; it is strange that the valves were never described until this year. It 

 is widely distributed as a fossil species, and, had we included its synonymy, 

 as such, the list would extend to a page or more. Although the descriptions 

 by the older writers are sufficiently comprehensive for a perfect recognition of 

 the species by its tube alone, still it is very questionable, whether, consider- 

 ing that Dr. Gould was the first to describe the entire Mollusk, the credit 

 should not be given to him for the species.
