W. H. Hudson of Buenos Ayres, have all recently sent col¬ 
lections to London, which have come under our examination. 
Besides these, M. Taczanowski, of Warsaw, has lately visited 
this country for the purpose of comparing some of the speci¬ 
mens lately collected by M. Jelski in Central Peru with our 
named series. The result has been the determination of 23 
new species, which were described by M. Taczanowski at a 
recent meeting of the Zoological Society. It must be recol¬ 
lected that these are additional to the new species lately de¬ 
scribed by Dr. Cabanis from the same collection. It is cer¬ 
tainly Remarkable that a district already visited by Tschudi 
should have yielded such novel results, and gives a good idea 
of the richness of the Andean avifauna. 
We have now concluded a summary notice of the principal 
events in geographical ornithology that have lately taken 
place. We hope to be able to continue the subject in the 
next number of f The Ibis 9 by the addition of a few remarks 
on the monographs and works bearing on the general scope 
of ornithology lately published or in preparation.

Sir,— I observe that Lieut. Legge, at p. 9 of his interesting 
paper in the present volume of ‘The Ibis/ on the birds of 
Southern Ceylon, refers the Spilornis inhabiting that district 
to S. cheela , but mentions that it there “ appears to average 
smaller dimensions than in India.” 
Mr. Holdsworth, on the contrary, in the P. Z. S. for 1872, 
at p. 412, refers the Spilornis of Ceylon to S. bacha (Daudin), 
of which S. bido (Horsfield) is a synonym. 
All the Ceylonese specimens of Spilornis which have come
