broadly tipped with bright purplish-black——tThe third list of 
birds collected in Ecuador by M. Stolzmann contains twelve new 
species. L. Taczanowski and Count Berlepsch contribute the 
article (P. Z. S., 1885), and the latter appends some general con- 
siderations on the ornithology of Western Ecuador.. This fauna 
now includes 468 species, besides eighty-five from Pichincha, Nan- 
egal and Quito. Eastern Ecuador must be richer in birds, since 
Messrs. Sclater and Salvin state that Mr. Buckley collected nearly 
800 species there. It also appears that there are but few species 
peculiar to Ecuador as a whole.——lIt appears from a note of 
Professor Owen, that the heart of the Apteryx has characters 
resembling those of Ornithorhynchus. This is especially the 
case with the auriculo-ventricular valve.
