Ohs. The above synonymy is retained for historical purposes. The only species 

 left in the genus by Hall and Clarke is the type species, Rhynchonella for- 

 mosa, which seems to be nothing more than a Rhynchotrema. This will 

 leave Stenochisma without a species. This name, however, should not dis- 

 place either Rhynchotrema or Camarotoechia, since it was not defined, and in 

 addition to this was founded by Conrad upon an erroneous identification. 

 Nor can the view of CEhlert be adopted, i. e., that Stenochisma should dis- 

 place Camaroi^horia King, because Conrad gave as the type C. schlotheimii. 

 This name did not apply to von Buch's species, but to the shell now known 

 as Rhynchonella formosa Hall. 



All the species formerly referred to Stenochisma will be found under Camarotoe- 

 chia except R. formosa, which is referred to Rhynchotrema. 



Stenocisma Hall, 1857 (non Conrad, 1839, Hall, 1867)=Zygospira.
