By the subjoined table (Appendix), showing the geographical distribution of all the known 

 Philippine species, it will be seen that 11 of the genera are peculiar, namely Pseudoptynx, Dasy- 

 lonlms, Lepidogrammus, Penelopides, Pseudolalage, Zeocejfhus, Bliahdornis, Sarcops, Phabotreron, 

 PtilocoJpa, and Amauromis. 



It will be further observed that the precise habitat of 57 Philippine birds remains still 

 unrecorded, and that out of the total number of Philippine species 91 are recorded from Luzon 

 alone. Of the 102 species known to inhabit other islands of the archipelago, 40 possess also a 

 Tr. Z. S.ix. Luzon habitat. If we assume, which we may fairly do, that the 57 species classed under the 

 P' ^^^' 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 190. The number of species known to 

 inhabit the remaining islands is given at the bottom of their respective columns, the in- 

 completeness of our knowledge with regard to thera 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 omission of many other large islands. Of Mindanao, with an 

 estimated area of 30,000 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 Calamines, 

 and the multitude of smaller islands are almost absolutely unknown. 



As might be anticipated from analogy with other isolated areas, some of the Philippine 

 islands, although only separated by narrow seas, possess species peculiar to themselves. Although
