396 Mr. W. R. Ogilvie Grant on the 



in the Military Library at Manilla. This bird is doubtfully 

 referred to A. gingica by Lord Tweeddale, but anyone com- 

 paring von Martens^s description with the plate must see at 

 once that they differ in nearly every point. What the bird 

 preserved in the Military Library really is remains to be 

 proved ; but even supposing that Luzon should be the true 

 home of A. gingica, there is no reason why a second and 

 perfectly distinct species should not exist in the same island. 

 I am sure that when Luzon is properly explored a number of 

 new or half-forgotten species will come to light, and that the 

 visit of some enterprising naturalist, who would thoroughly 

 work the hills of the interior of that island, would be well 

 repaid.

The feathers producing the line of white spots along each 

 side of the crown and throat are very curious, being naked 

 shafts bearing a white plume at the extremity. Similar struc- 

 tures are found among the feathers of the crown in the next 

 species, A. brunneopectus , but owing to their extremities being 

 black they are less conspicuous.
