The familiar name Carama can no longer be used for these 

 species. It is antedated by Norape Walker ; but it is not 

 properly available in any case. Walker founded the genus 

 upon what he supposed was sparshalli Curtis, and sparshalli 

 should therefore be taken as the type, whatever may have 

 been actually before Walker at the time. He has specified 

 sparshalli as the type, being the only included species, and 

 this action is more vital to nomenclature than his descriptions. 

 Sparshalli appears to be an Australian species. Carama will 

 therefore become a synonym of Trichetra West wood.
