630 U.S. NATIONAL MUSEUM BULLETIN 221 



Ridgway based this form upon four specimens, of which one, No. 23890 

 from Venado Island, is now considered representative of another race. Of 

 the remaining three, one said to be from Cordoba, the property of George 

 N. Lawrence, is probably deposited in the American Museum of Natural 

 History, New York. 



Richmond has for some unexplained reason set aside No. 22443 as the 

 type, despite the fact that it is the only one of three wholly devoid of useful 

 data. It is, of course, but one of three cotypes.

No. 39281 had entered the private collection of Robert Ridgway by ex- 

 change prior to Ridgway 's establishment of the race verticalis; as usual with 

 such specimens, its original label was removed and replaced with Ridgway 's 

 own. 



The word "Type" in Ridgway's hand appears on the reverse side of each 

 of the three labels.
