32. Ridgway on the Generic Name Uropsila. 



[Note on the Generic Name Uropsila, Scl. & Salv. By Robert Ridg- 

 way. Proc. U.S. Nat. Mus. 1887, p. 511.] 



Mr. Ridgway proposes to alter the generic term Uropsila 

 to Hemiura, because Uropsilus was used previously for a genus 

 of mammals. If this be necessary, can we continue to employ 

 Picus and Pica (as Mr. Ridgway does himself) and many 

 other terms which nearly resemble one another ?
