was furnished to Swainson by the Hudson Bay Company, 
and was most probably therefore killed north of the Colum- 
bia river. No specimen exactly like it has been lately 
obtained. 
NORTHERN SHRIKE (C. borealis). shot a specimen, the 
only one I saw, at Fort Dalles, October 15th,— early in the 
season for it to appear even in that latitude. It was savagely 
attacking Jays and Magpies, driving them before it, but it 
did not kill any birds while I übedcved it. 
Vinko (Vireo olivaceus? V. Bartramii Swainson?). I 
found this species quite common from the eastern base of 
the Rocky Mountains to that of the Bitterroot Range, and 
in habits found it exactly like the eastern olivaceus. As it 
is larger than that mentioned by Swainson, his specimen was 
very probably, as Baird suggests, of the next species, espec- 
ially since this is found unchanged at Fort Bridges, Utah. 
WannBLING Vireo ( V. gilvus). Rather less common than 
the preceding in the Rocky Mountains, though very common 
west of the Cascade Range. I noticed nothing new in its 
habits. — To be continued.

Waen the agent of the Central American Transit Company 
announced to us, that on account of the low water, we might 
be detained a day or two at Greytown, we did not consider 
ourselves unfortunate by any means. A collecting party 
was quickly organized, and, after partaking of fried plan- 
tains and “tortillas,” with a cup of coffee from the hands of 
a señorita very much the color of the beverage just men- 
tioned, each one started out prepared to make the best of 
the six hours of daylight remaining, by dispersing into the 
bushes in search of specimens of all kinds. Previous, how-
