412 ZOOLOGICAL GEOGRAPHY. [PART III. 
The most prominent deficieftcies, as compared with Australia, 
are in Sylviide, Timaliide, Ploceide, Platycercide,and Falconide. 
II. The genera which are characteristic of the whole Malay 
Archipelago are the following (10) :— 
1. Erythrura ... (Ploceide) 6. Loriculus ... (Psittacidz) 
2. Pitta... ... (Pittide) 7. Macropygia ... (Columbide) 
3. Ceyx ... ... (Alcedinide) 8. Chalcophaps ... - 
4, Calao ... (Bucerotide) 9. Calenas sa 
5. Dendrochelidon (Cypselide) 10. Baza ... --- (Falconide) 
III. The curious set of genera apparently of Indo-Malayan 
origin, but unknown in the Moluccas, are as follows :— 
1. Eupetes ... (Cinclide) 4, Arachnothera (Nectariniide) 
2. Alcippe ... (Timaliide) 5. Prionochilus... (Diceeidee) 
3. Pomatorhinus ‘ 6. Eulates ... (Sturnide) 
The above six birds are very important as indicating past 
changes in the Austro-Malay Islands, and we must say a few 
words about each. (1) Hupetes is very remarkable, since the 
New Guinea birds resemble in all important characters that 
which is confined to Malacca and Sumatra. They are pro- 
bably the. :survivors of a once wide-spread Malayan group. 
(2) Alcippe or Drymocataphus (for in which genus the birds 
should be placed is doubtful) seems another clear case of 
a typical Indo-Malayan form occurring in New Guinea and 
Java, but in no intervening island. (3) Pomatorhinus is a most 
characteristic Himalayan and Indo-Malayan genus, occurring 
again in New Guinea and also in Australia, but in no interme- 
diate island. The New Guinea bird seems as nearly related to 
Oriental as Australian species. (4) Arachnothera is exactly 
parallel to Alcippe, occurring nowhere east of Borneo except in 
New Guinea. (5) Prionochilus, a small black bird, sometimes 
classed as a distinct genus, but evidently allied to the Prionochili of 
the Indo-Malay Islands. (6) Hulabes, the genus which contains 
the well known Mynahs of India, extends east of Java as far as 
Flores, but is not found in Celebes or the Moluccas. The two New 
Guinea species are sometimes classed in different genera, but they 
are undoubtedly allied to the Mynahs of India and Malaya. 
We find then, that while the ornithology of New Guinea is
