grandis (Tumbe, Peru, type in Vassar College), Empidonax atri- 
rostris (Venezuela?, type in Cab. Lawr.) and Myiarchus Yueat- 
anensis. This last is highly interesting, owing to the novel 
identifications it implies. It is what Mr. Lawrence in 1869 (Ann. 
Lye. Nat. Hist., N. Y.) called M. “ Mexicanus Kaup,” whilst 
contending, very properly, for the distinction between his cineras- 
cens and Kaup’s bird. To everybody’s surprise, Kaup’s Mexicana, 
only lately identified, proves to be what Baird called M. Cooperi 
in 1 This announcement of Dr. Sclater’s, upon examination 
of Kaup’s type specimen, of course makes quite a commotion in 
the synonymy of the several species implicated.— E. C.

New Parasric Prant or tun Misrieror Fammy.— Miss Mil- 
lington of Glens Falls, N. Y., sends some specimens of the curious 
new parasite which she discovered last summer in Warren and 
Essex Counties, N. Y. and which have very much interested 
our botanists, It grows upon the branches of Black Spruce 
trees so abundantly that it has evidently injured, and apparently 
killed, some of the trees most infested by it. Arceuthobium Oz- 
ycedri of Bieberstein grows on juniper trees in the Caucasus rm 
gion, and here and there in Southern Europe as far west as Spur : 
This was the only species known, and the only habitat, until z 
Sir William Hooker brought to light American plants growing : 
on Pine trees in the Hudson’s Bay region and west to Oregm i 
and gave a good figure in his Flora-Boreali Americana, referring ‘ 
it to Bieberstein’s species. Mr. Nuttall, however, distingus B 
this American species as O. Americanum; and Dr. Engot 
about twenty-five years ago distinguished two more species” 
the far west and south west. These plants are a sort of ‘ale 
_ toe, of diminutive size, with small scales at the joints int w 
of leaves. They were unknown nearer to us than Hode .

prised us by sending, for a name, a specimen of an Areeul! Pak

Millington, to whom belongs the credit of first detecting we f 
plant, sent her specimens later. She found it in two localities :
