14 U.S. NATIONAL MUSEUM BULLETIN 221 



32519. Adult (sex not indicated). Canary Islands, eastern Atlantic 



Ocean off northwestern Africa. Entered into the museum register on 



March 9, 1864. Collected by (or for) Philip Barker- Webb. Received 



from the Academy of Natural Sciences, Philadelphia. 



The original label for this specimen has disappeared without trace; the 



modern label has data transcribed from the register in Riley's hand. 



The number of cotypes is not now known. One in the British Museum, 

 with identical data, was acquired from Edward Wilson, brother of Thomas 

 B. Wilson, patron of the Academy of Natural Sciences; it is therefore prob- 

 able that our specimen reached the Academy through the same agency. No 

 example from the Canaries is now to be found there. 



The name ProceUaria columbina appears on plate 4 of livraison 31, which 

 was published in July 1838; the name Puffinus columhinus is used in the 

 text on page 44 of livraison 63, which did not come out imtil May 1842. 



Family HYDROBATIDAE: Storm Petrels 



Genus OCEANITES Keyserling and Blasius 



Thalassidroma gracilis Elliot 

 Ibis (1) 1:391, October 1859. 

 =Oceanites gracilis gracilis (Elliot). See Murphy, Oceanic birds of 



South America 2: 757, 1936. 

 370444. Adult male. Chile. 



The specimen bears the green label of the Maison Verreaux; on tlie label's 

 obverse side are the words "Thalassidroma Gracilis./D. G. Elliot.-/Chili 

 5 .," while on the reverse side appear the numbers "(4096) 33923." 



This is traditionally Elliot's type; it has been in the collection for many 

 years, although it was not entered into the museum register until January 

 7, 1942. It is of course improbable that the bird's true history can ever now 

 be known.
