Ibis Vol. 6 1864 —

Mr Wallace on genus Pitta, excellent remarks on each island having its own species. The one species which has wide range in India presents several unstable forms graduating into each other. The little Isd of Banca has 2 endemic species; & the 2 species of which they seem to be modifications are common to Sumatra & Borneo. Discusses this case & shows that the nearness of Banca to Sumatra is probably illusory.

Ibis 1865 p. 225 The absence of Alauda cristata from Sardinia is very remarkable, even more so than its nonoccurrence of the N.W. of the Straits of Dover whilst so plentiful between Calais & Boulogne.

p. 346 Prof Baird insists on the number of specimens, especially from cliff localities to make out species of birds.
