of the Genus Thriponax. 141 



his Monograph. Cabanis and Heine^ in the ' Museum 

 Heineanum/ admit four species — T. javensis [leucogaster of 

 Malherbe)^ T. hodgsoni, T.jerdoni, and T. hodgei. Sundevall, 

 in his ' Conspectus Avium Picinarum/ follows tlie conclu- 

 sions of the above-named authors. T.jerdoni of Cabanis and 

 Heine is T. feddeni (Blanford). Both descriptions were 

 published in 1863, bat Blanford's name has always been held 

 to have priority. Plcus crawfurdl of Gray also belongs to 

 the genus Thriponax, but has been omitted by all the above- 

 mentioned writers; its validity has been discussed by me 

 below. 



My thanks are, as usual, due to Dr. Giinther and 

 Mr. Sharpe for the facilities for study afforded me at the 

 Natural History Museum, and also to Captain Wardlaw 

 Ramsay for the loan of his series of Philippine specimens, 

 some of which are not represented in any other collection.
