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 co?i-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. 7-uhrinucha 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. cyanojjtera of Sumatra, and P. hangkanu, 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) the 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. SchlegePs next contribution, relating to the 

 Fruit-pigeons allied to Treron aromatica, we have already given
