gether peculiar to it. Only eight laud-birds are common to it and 

 the Moluccas, viz. Merops ornatus, Munia molucca, Eurystomus 

 pacificus, PtUonopus superbus, Turtur chinensis, Hirimdo javanica, 

 Todiramphus coUaris, and Scijthrops nova hollandm ; and most 

 of these are birds of a very wide range in the Archipelago, only 

 one in fact, the PtUonopus, being a strictly IMoluccan bird, and 

 that differs almost enough to be considered distinct. The birds 

 of Java, Borneo, and Timor are, on the other hand, better repre- 

 sented, as might be expected, from those islands entirely sur- 

 rounding the southern and western parts of Celebes ; yet not 

 more than twenty species of these occur, leaving about 100 land- 

 species altogether peculiar to this island. Such a disproportion 

 probably occurs nowhere else in the world, even in islands less 

 favourably situated for receiving immigrants. 



On the whole, therefore, though disappointed as to the num- 

 ber and variety of species, I cannot but consider the island of 

 Celebes to be one of the most interesting in the world to the 

 philosophical ornithologist, and well worth the time I have be- 

 stowed upon it. The Dutch naturalist Forsten having resided 

 a year and a half at Menado with unlimited means and Govern- 

 ment assistance, I cannot hope to have made many discoveries ; 

 I trust, however, that one or two of the smaller species may 

 prove new.

XVII. — On an undescribed Species of Hawk from New Granada. 

 By Philip Lutley Sclater. 



(Plate VI.) 

 Although the Accipitres generally are birds of wide distribu- 

 tion, instances of species being confined to narrow geographical 

 limits are not wanting even in this group. The mountain- 

 valleys of New Granada — so fertile in zoological novelties of 

 every sort — have produced several birds of prey which arc not 

 known to occur elsewhere. The curious Milvacjo carunculatus^ , 

 described from a single specimen, now, we believe, in the 

 Museum of the Academy of Natural Sciences of Philadelphia,
