Acad. Nat. Sci. Philadelphia 58: 199-200, 1906; Peters, Checklist of

 14331. Adult (sex not indicated). Samoan Islands, Oceania. Original 



number 520. U.S. Exploring Expedition (1838-1842) . 

 Cassin's ms. list shows that he had five of this species, but there are six 

 entries of birds with original number 520 in tlie museum register. Un- 

 fortunately, both Peale and Cassin lumped specimens from Samoa and the 

 Fijis (C s. assimilis) under the name spodiopygia, and two entries in the 

 register lack information on provenience; it is thus no longer possible to 

 say how many of the original series were cotypes of spodiopygia as it is now 

 understood. 



No. 14327, from Upolu, has disappeared without trace ; No. 14329, without 

 locality, is in the collection and agrees with spodiopygia (but note comment 

 on No. 14334, below) ; No. 14331, from the "Samoan Islands" ("Upolu" 

 written on the label in Oberholser's hand, but why not "Tutuila"?), is 

 treated above; No. 14332, from Tutuila, is missing but probably is the cotype 

 from Tutuila now in the Museum of Comparative Zoology (where it is No. 

 75700); No. 14333, without locality (and thus possibly assimilis), cannot 

 be found; No. 14334, from the "Fijis," is, if correctly labeled, an example of 

 assimilis, but at this date cannot be distinguished from Samoan specimens. 



In short. No. 14331 is the only specimen now in the national collection that 

 may properly be considered a cotype. No. 14329 may well have an equivalent 

 status, but its claim is vitiated by the fact that No. 14334 (which may or may 

 not be correctly labeled) is inseparable from it.
