Rapaces, by Dr. Schlegel, a catalogue of the specimens of Pitta, 
by Dr. Schlegel, and the commencement of a catalogue of what 
is termed “ Buccones,” by Lieut. A. Goffin. The general resume 
of the “Aves Rapaces” shows that the Leyden collection now 
contains 2002 specimens, illustrating 333 species of this group 
of birds. This is probably only surpassed by the series in the 
collection of the Norwich and Norfolk Museum, towards the 
perfection of which Mr. J. H. Gurney has devoted so much time 
and trouble. 
The series of the genus Pitta in the Leyden Museum has long- 
been celebrated for its extent and beauty. Prof. Schlegel cata¬ 
logues 29 species, appearing in this group to ignore what he has 
hitherto termed cow-species, and to consider all the representative 
forms of the different islands of specific value. The deficiencies 
of the Leyden Museum appear to be four only, namely, P. cyanea , 
Blyth, of Aracan, P. rubrinucha of Bouru, P. crassirostris of the 
Sula Islands, and P. nympha of China. Two species new to 
science are recorded, both from the island of Bangka, between 
Sumatra and Borneo. These are, Pitta megarhyncha, representing 
P. cyanoptera of Sumatra, and P. bangkana, representing P. 
atricapilla of Borneo. But the singular fact is this, and one 
almost without parallel, as far as we know:—if P. bangkana be 
really distinct, we have a species occurring in Borneo and Su¬ 
matra, and a different one found in an island exactly inter¬ 
mediate between these two. 
The second livraison of the ‘ Nederlandsch Tijdschrift voor 
de Dierkunde' contains several ornithological articles. Dr. 
Schlegel describes (p. 56) th e Buceros nagtglasii, already referred 
to in his catalogue of the specimens of this group in the Leyden 
Museum. This is perhaps the same as Mr. Gould's Toccus 
hartlaubi, P. Z. S. 1860, p. 380. Next follows the same author's 
notice of three species of Ptilopus —P. bernsteini, P. hugonianus, 
and P. insolitus. Dr. Schlegel has already communicated a 
note on the synonymy of the first of these species (see antea , 
p. 120). On Dr. Schlegel's next contribution, relating to the 
Fruit-pigeons allied to Treron aromatica , we have already given
