432 ZOOLOGICAL GEOGRAPHY. [PART III. 
greatest on the Austro-Malay or Australian side. We have now 
to consider what further light can be thrown on the subject by 
the consideration of the peculiar genera of Celebes, and of those 
curiosities or anomalies of distribution to which we have 
referred. 
Nine genera of birds are altogether peculiar to Celebes ; three 
more are found only in one other island, and seem to be typi- 
cally Celebesian ; while one is found in the Sula islands (which 
belongs to the Celebes group) and probably exists in Celebes 
also. The following is a list of these 13 genera: 
1. Artamides.... (Campephagide) 8. Monachalcyon (Alcedinide) 
2. Streptocitta.. (Corvide) 9. Cittura... es 
3. Charitornis.. _ 10. Ceycopsis ... 4 
4, Gazzola, (s. g.) 11. Meropogon .. (Meropide) 
5. Basilornis .. (Sturnide) 12. Prioniturus. (Psittacidee) 
6. Enodes * 13. Megacephalon (Megapodiide) 
7. Scissirostrum - 
Of the above, Artamides, Monachalcyon, Cittwra, and Megace- 
phalon, are modifications of types characteristic of the Australian 
region. All are peculiar to Celebes except Cittwra, found also in 
the Sanguir islands to the northward, but which seems to belong 
to the Moluccan group. Streptocitta, Charitornis, and Gazzola, 
are peculiar types of Corvide; the two former allied to the 
magpies, the latter to the jackdaws. Charitornis is known only 
from the Sula islands east of Celebes, and is closely related to 
Streptocitta. There is nothing comparable to these three groups 
in any of the Malay islands, and they seem to have relations 
rather with the Corvide of the old-world northern continent. 
Basilornis, Enodes, and Scissirostrum, are remarkable forms of 
Sturnide. Basilornis has a beautiful compressed crest, which in 
the allied species found in Ceram is elongated behind. nodes 
has remarkable red superciliary streaks, but seems allied to 
Calornis. Scissirostrwm seems also allied to Calornis in general 
structure, but has a very peculiarly formed bill and nostrils. We 
can hardly say whether these three forms show more affinity to 
Oriental or to Australian types, but they add to the weight of 
evidence as to the great antiquity and isolation of the Celebesian 
fauna, Scissirostrum has been classed with Huryceros, a Mada-
