TYPE SPECIMENS OF BIRDS 97 



185437. Adult male. Sihuatanejo, State of Guerrero, Mexico. April 9, 

 1903. Collected by Edward W. Nelson and Edward A. Goldman. 

 Original number 9459. Received from the U.S. Fish and Wildlife 

 Service. 

 Flaliplana fuliginosa var. crissalis "Baird, M.S." Lawrence 



in Grayson, Proc. Boston Soc. Nat. Hist. 14 : 285,, April 1872. 

 =Sterna fuscata crissalis (Lawrence). See Peters, Checklist of birds of 



the world 2: 338, 1934. 

 50861. Adult male. At sea between the Tres Marias Islands and the 

 Revilla Gigedo Islands, not far from lat. 20°38' N., long. 108°00' W. 

 {fide Grayson, op. cit., p. 288) , eastern Pacific Ocean off Mexico. May 

 9, 1867. Collected by Andrew J. Grayson. Original number 703. 

 58792. Adult (sex not indicated). Locality data same as for No. 50861. 



Original number 702. 

 The type locality for this form has consistently been given as Socorro 

 Island, but, while the bird was reported as occurring there {op. cit., p. 301), 

 it appears that no specimens were taken. Only two examples of the "black- 

 billed tern" were received at the Museum as a result of this trip, and it can 

 hardly be doubted that they are the ones mentioned by Grayson on p. 288, 

 especially since he gave them consecutive original numbers. The type 

 locality is thus in closer proximity to the Tres Marias than to the Revilla 

 Gigedos.
