Mr. P. L. Sclater on the Distribution 
but of different plumage. This last will probably have been the 
immature Bambusicola sonorivox. 
Amoy, 17 June, 1866. 
*** The following is an extract from a letter, dated “ 4th May, 
1866,” from Mr. Swinhoe, which unfortunately did not reach us 
until after the publication of our last Number. “ If you have not 
yet printed my paper on recent novelities from Formosa, I must 
ask you to correct an error for me. I have now a goodly series of 
Green Pigeons, and find them to be as variable in colour, form, 
and size of bill, and other proportions, as Mr. Darwin could desire. 
I think I was wrong in making three species. The skins of the 
first Sphenocercus sororius that I received were so badly stuffed 
that I could not then reconcile them with what I considered the 
third form, my Treron cheer oboatis [antea , p. 313]. Now, how¬ 
ever, after examining a large series, I consider the two last to be 
identical, and I should be obliged by your uniting them under 
the first name, Sphenocercus sororius. Treron formosa is a good 
species; but, with the exception of some slight differences in the 
tail, I think there is scarcely enough to justify the two forms 
being referred to distinct genera, though I believe I am right in 
referring sororius to Sphenocercus, and/ormos*® to Treron .”— Ed. 
XXXII.— Note on the Distribution of the Species of Chasmo- 
rhynchus. By P. L. Sclater, M.A., Ph.D., F.R.S. 
In Mr. Salvin's excellent article upon the wonderful Bell-bird 
of Costa Bica ( Chasmorhynchus tricarunculatus) and its allies, 
published in last year's ‘Ibis' (1865, p. 90), he follows M. 
Temminck and myself * in giving “ Brazil '' as the locality 
of C. variegatus. I have lately discovered that this locality, 
vague as it is, is most probably altogether incorrect. During 
my visit to Copenhagen last year, Professor Beinhardt was kind 
enough to show me an example of this species in the Boyal 
Museum, obtained by a correspondent of that Institution, M. 
Schibby, near Valencia, in Venezuela. In the ‘Museum 
Heineanum' (vol. ii. p. 108) Messrs. Cabanis and Heine give 
Puerto Cabello, on the coast of the same republic, as the 
* Cat. Am. Birds, p. 258.
