 liams County, North Dakota. 



It may be mentioned here that Stone (Proc. Acad. Nat. Sci. Philadelphia 

 51: 18, 1899) has erred in referring to our cotype as No. 1854, instead of 

 No. 1884.

Family PTILOGONATIDAE: Silky Flycatchers 



Genus PTILOGONYS Swainson 



P[tiliogonys]. cinereus molybdoplianes Ridgway 



Manual of North American birds, p. 464, September 1887. 

 =Ptilogonys cinereus molybdoplianes Ridgway. See Helhnayr, Catalogue 



of birds of the Americas 8: 106, 1935. 

 30719. Adult male. Duenas, Department of Sacatepequez, Guatemala. 

 1861. Collected by Osbert Salvin and Frederick DuC. Godman. Orig- 

 inal number 377. Received from Osbert Salvin. 

 50453, Adult male. Guatemala. Entered into the museum register on 



Mar. 4, 1868. Collected by C. H. Van Patten. 

 Ridgway described only the male of his new form and indicated by his 

 measurements that at least two specimens lay before him. The two listed 

 above seem to have been the only males from Guatemala in the museum 

 collection in 1887. The oldest label borne by No. 50453 is Ridgway's own, 

 so it appears that this is another bird, rare at the time, that left the museum 

 to enter the curator's private collection.
