TYPE SPECIMENS OF BIRDS 15 



41950. Adult (sex not indicated). Same data as No. 41949. 

 Neither skin carries an original label. The label of No. 41949 has the data 

 in Ridgway's hand; that of 41950 has it in Stejneger's hand and on the 

 reverse side the word "Type" written by Ridgway. Reference to the original 

 description shows that the two have equal standing as cotypes.
