" By the subjoined table, showing the geographical distributions of 

 all the known Philippine species, it will be seen that 1 1 of the 

 genera are peculiar, namely Pseudoptynx, Dasylophvs, Lepido- 

 grammus, Penelopides, Pseudolalaye, Zeocephus, Rhabdornis, 

 Gymnops, Phapitreron, Ptilocolpa, and Amaurornis. 



" It will be further observed that the precise habitat of 54 Philip- 

 pine birds remains still unrecorded, and that out of the total number 

 of Philippine species 85 are recorded from Luzon alone. Of the 76 

 species known to inhabit other islands of the archipelago, 49 

 possess also a Luzon habitat. If we assume, which we may fairly 

 do, that the 54 species classed under the general term of Philippine 

 in the table are nearly all, if not all, inhabitants of Luzon, the total 

 number of species known to inhabit that island will be 139. The 

 number of species known to inhabit the remaining islands is given 

 at the bottom of their respective columns, the incompleteness of our 

 knowledge with regard to them being illustrated by the small total 

 of 19 representing the number of authentic species in the large and 

 important island of Mindanao, and also by the entire and enforced 

 omissions of many other large islands. Of Mindanao, with an 

 estimated area of 36,000 square miles, the few species we know come 

 from the immediate neighbourhood of Zamboanga. Of Luzon, the 

 whole of the island north of Manilla has yet to be explored. The 

 islands of Palawan, Mindoro, Samar, Leyte, Masbale, Bohol, the
