MR. A. H. GARROD ON THE 



[June 3, 



Calamines, and the multitude of smaller islands are almost abso- 

 lutely 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 well defined, 

 these are strictly representative forms. Those that are known are 

 given below ; and doubtless many more cases of representation will 

 be discovered when the islands have been more thoroughly explored. 



" Table showing the Representative Forms which are known to 

 inhabit the Philippines only. 



" Only one species is common to a Philippine island and to any 

 one other non-Philippine island, namely Xantholcema rosea, which 

 is restricted to the islands of Negros and of Java. X. hcemacephala, 

 the common Luzon Barbet, which ranges all over India and is 

 found in Sumatra and the Malay peninsula, does not seem to occur 

 in Negros, where Z. rosea appears to represent it, as it also does in 

 Java. 



" It is also a remarkable fact that the only Philippine representa- 

 tive of the highly characteristic Indian family of the Pericrocotidce 

 is the abnormal and only migratory member of the group, P. 

 cinereus."

Through the kindness of Prof. Flower, I have had the opportu-

 in spirit, as well as the skeleton of another ; and Mr. Sclater has also 

 kindly given me a skin to assist in the study of the pterylosis, and a
