Picoides tridaclylus alasceiisis Nelson 

 Auk 1 (2) : 165, April 1884. 

 =Picoides tridactylus jasciatus Baird. See Ridgway, Birds of North 

 and Middle America 6:295,296, 1914; A.O.U., Checklist of North 

 American birds, ed. 4, p. 200, 1931.

 L. N. McQuesten for Edward W. Nelson. Original number 1161. 



78615. Adult male. Fort Reliance, Alaska. November 11, 1878. Col- 

 lected by L. N. McQuesten for Edward W. Nelson. Original number 

 1164.

 ber 1168. 

 This form was originally described as from "Alaska and northern British 

 America," but no specimens were definitely mentioned. 



Since the name given was alascensis, the types must be chosen from the 

 Alaskan section of Nelson's series, and preferably from among specimens in 

 his own collection. This will immediately remove from consideration the 

 locality Nulato, given by Ridgway [op. cit., p> 296), since the species was 

 collected there only by Turner. In any case, the type locality had already 

 been inferentially restricted to Fort Reliance and a type specimen selected 

 prior to Bangs's revision of the group (Auk 17: 132, 1900). 



Nelson, in Birds of Alaska ([Arctic Series of Publications, Signal Serv- 

 ice U.S. Army 3], p. 160, 1887), listed by original numbers six specimens 

 from Fort Yukon and Fort Reliance. Presumably, although these six 

 represented but a small proportion of his entire series, the type should have 

 been selected from among them. The bird set aside by Richmond (No. 

 78615) is not there listed however; on the other hand, of the six only one 

 can now be found in the collection (and that an example from Fort Yukon) . 

 Accepting Fort Reliance, Alaska (not Mackenzie, as believed by Bangs), 

 as the restricted type locality, I have listed as cotypes all Nelson's birds 

 from that place still in the museum.
