=Melanerpes formicivorus striatipectus Ridgway. See Peters, Checklist 



of birds of the world 6: 160, 1948. 

 39798. Adult male. Birris ("the locality in the region of a small river of 

 the same name which flows through a very deep gorge into the Rio 

 Reventazon between Paraiso and Juan Viiias," fide Carriker, Ann. 

 Carnegie Mus. 6: 335, 1910), Province of Cartago, Costa Rica. May 

 17, 1865. Collected by Jose C. Zeledon. Original number 69. 

 Ridgway based this form upon an undisclosed number of specimens from 

 "Middle America, south of Orizaba and Mirador." At some time after 1910 

 the late Charles W. Richmond inferentially restricted the type locality to 

 Birris, Costa Rica, by labeling as the type No. 39798, and his action was to 

 be made official by Ridgway himself in his Birds of North and Middle Amer- 

 ica (6: 111, 1914). No. 39798 can be, however, no more than a lectotype, 

 since it can be shown that Ridgway had before him in 1874 not less than 

 eight specimens from Costa Rica, and of these not less than three from Birris. 

 Indeed, Richmond's choice seems to have been quite capricious, since Ridg- 

 way's diagnosis relied more upon characters of the female than of the male. 

 Accepting Birris as type locality, we must have not fewer than three co- 

 types, of which only one is now in the collection. No. 39800, a male taken 

 on May 15, 1865, was sent on February 28, 1887, to Robert Collett and may 

 still exist in the museum at Oslo ; No. 39799, a female of the same date, seems 

 to have disappeared from Washington without trace.
