Wings. 



Dusky slate or grayish Fuscous, tertials faint- .Graj'ish brown faintly 

 brown, inner tertials ly edged with whitish, iridescent, the coverts 

 lightly edged with white. slightly, tertials more 



widely, margined with 

 huffy or ochraceous. 



' It is of course well known that in the Tree Swallow both birds 

 of the year and adults moult before leaving us for the South while 

 the Cliff Swallow migrates before moulting. It is consequently 

 of interest to observe that in this hybrid moult has begun normally 

 with the innermost primaries. 



This fact is also of importance in determining the bird's age and, 

 in connection with the unworn condition of the wing-feathers, it 

 leaves no doubt that the specimen is in post-natal plumage. 



The radical differences in the character of the nests of the sup- 

 posed parents of this bird lead one to speculate on the type of 

 nest-structure in which it was reared, but, unfortunately, our curi- 

 osity in this direction cannot be gratified. 



GENERAL NOTES. 



H The Arctic Tern in Hawaii. — When shooting in the low, brackish- 

 water marshes at Kahuku, on the island of Oahu, on April 30, 1902, 

 Manuel Silva, a Portuguese boy of my acquaintance, shot a fine male 

 specimen of Sterna faradiscea in full spring plumage. I secured the bird

 15.25; wing, 11.50; culmen, 1.20; tarsus, .47; middle toe and claw, .91 ; 

 tail, 7.25. 



The boy said that it was the only one of the kind that he saw, and it 

 being a stranger to him he spent much time in pursuit of it and was for- 

 tunate enough to secure it by a chance shot. The bird was in good flesh 

 and exhibited no signs of having experienced any very severe hardship 

 in reaching this Territory. 



This is the second specimen of this species which has been reported 

 from the Hawaiian Islands, one having been taken eleven years before by 

 Mr. R. T. Guarde at Hilo on Hawaii, as reported by Mr. Henshaw in ' The
