ON THE GENUS PTILOPUS. 351 



the bill are dark (nearly black) in the latter, but orange-coloured in the 

 former (see also Mr. Wallace's figure, P. Z. S. 1862, pi. xxi.). 



In addition to Dr. Meyer's remarks, the following translation is of 

 interest : — 



Schlegel, Nederl. T. v. d. Dierk. iv. 1873, p. 25, sub P. humeralis : 

 " M. von Rosenberg found this Ptilopus again on the island of Jobi ; but 

 it offers some constant modifications in its coloration. The most conspicuous 

 is this, that the small wing-coverts are of a uniform greyish lilac, and that 

 they consequently do not show any trace of this fine purple violet, which 

 forms edgings in the individuals of the race from Western New Guinea and 

 the island of Salawatti. Besides, the dominant green of the plumage is, in 

 the race from Jobi, mostly strongly bronzed, especially on the head, on the 

 primaries, and on the upper surface of the tail-feathers." 



Schlegel, Mus. P.-B. Col. 1873, p. 16, sub P, humeralis jobiensis : 

 " Similar to P. humeralis, but of somewhat smaller size, and without 

 purple patches on the small wing- coverts." 



The total length of the bird figured, which is in my own collection, is 

 7 inches ; and the illustration is for the purpose of comparison with (Edirhinvs 

 insolitus (Plate LXVL).
