 Originally four species, S. adamsumts, S. tetra- 

 dactylus, S. gracilior, and S. rogersianus, were as- 

 signed to this genus. The last-named belongs 

 under Palamopus. Later (1848) Hitchcock re- 

 ferred the first three species to Ornithopus, a 

 new genus. As Sillimanius was based on de- 

 scribed and figured forms, Ornithopus becomes 

 a synonym.
