BovALLius' Collection: 1 (^, 1 $, Bayoneta, April 14. 



The Oyster-catcher was very common at low tide on the 

 shore of Punta Cocos. 



Thayer and Bångs say about the single specimen, an adult 

 female, which was collected by Mr. Brown, that it is rather 

 small, but E. W. Nelson, who examined it during a study 

 of the American Oyster catchers, considers its small dimen- 

 sions as only the extreme of individual variation. 



The present specimens show the following measurements, 

 which as may be judged compare very favourably with those 

 given in the Cat. Birds Brit. Mus. XXIV, 1896, 116. 



J: wing 248, tail 99, tarsus 57, culmen 84 mm. 



$: wing 254, tail 103, tarsus 57, culmen 89 mm. 



It is noteworthy, however, that the male specimen has no 

 white wing-markings on the shafts of the proximal primaries. 

 In the female there are such markings on the primaries 3, 4, 

 and 5 from the proximal side.
