him; and we wonder if he has ever tried Mr. R. Kearton’s 
portable artificial tree-trunk, of which he will find two 
illustrations (open and closed) in f Wild Life at Home/ 
pp. 12-13. Mr. Lee’s remark that each individual Barn-Owl 
seems to have its favourite food, as the pellets under one 
nest will contain only the remains of mice, and those under 
another tree all rats or small birds, is a much-needed warning 
against generalizing from scanty data. The letterpress is as 
good as usual, but some of the vignettes are rather deficient 
in interest. 
23. Madardsz on Birds from New Guinea . 
[Ornithologisclie Sammel-Ergebnisse Ludwig Biro’s in Neu-Guinea. 
Bearbeitet von Dr. Julius v. Madarasz. Termes. Fiizetek. 1899, p. 375.] 
Since the first list of Biro’s collection in German New 
Guinea was published (cf. ‘ Ibis/ 1898, p. 166), further 
consignments have been received at Buda-Pesth, together 
with a series of field-notes made by the collector. Dr. v. Mada¬ 
rasz now gives a complete list of Biro’s birds, accompanied 
by these useful notes. They are prefaced by an interesting 
letter from Biro, in which an account is given of his 
principal collecting-quarters, near the native village of 
Erima, about four kilometres N.W. of Stephansort, and of 
the natives of that district and their various languages. 
The list enumerates 103 species, among which is a rare 
Kingfisher, Halcyon elisabeth Heine, stated to be omitted 
in the B.M. Catalogue. This species is figured, as are 
also Rhipidura leucothorax Salvad., and Astur novae-guineas — 
a new discovery of Biro’s, which has been previously de¬ 
scribed by Madarasz (Orn. Mon. 1899, p. 27). Some breast¬ 
bones are figured in the text, also the curious chick of 
Centropus menebeki.
