VISCOUNT WALDEN ON THE BIEDS OF CELEBES.

further than what is found in 0. kundoo ; in others it has extended still further, until 

 it is found encircling the head. Unfortunately Dr. Meyer has not noted the localities 

 of the several individuals, and we are left in doubt whether there are two species or 

 one ; but, from the graduations the coronal ring exhibits, it seems likely that there is 

 but one species. This gradual development of the coronal ring has not been observed 

 in any other species of Broderipus, and, taken together with the almost total absence of 

 the wing-spot, separates the Celebean Oriole from all known species. 



Geocichla erythronota, Sclater, antea, p. 61. 



Several examples were collected in North Celebes. 



Tbichostoma celebense, Strickl., antea, p. 62. 

 Obtained in North Celebes. 



Aetamus monachus, Temm., antea, p. 67. 



Celebean examples are identical with those obtained in the Sula Islands. 



Geaucalus temminckii, S. Miiller, antea, p. 68. (Plate XII.) 



A few examples of this rare species were obtained iu North Celebes by Dr. Meyer. 



CoEVUS enca (Horsf ), antea, p. 74. 



Two examples sent by Dr. Meyer from Celebes give me the opportunity of comparison 

 with the Javan species. I am unable to detect any difference, except in the dimensions, 

 the Javan bird being somewhat the largest. C. validus, Temm., as represented at 

 Malacca is a very distinct species. 



Dimensions. 



Caloenis neglecta, Walden, antea, p. 79. 



Numerous examples of this species were obtained by Dr. Meyer in Celebes, thus 

 fully establishing its Celebean habitat.

On examination of a large series of the Celebean form from North Celebes I find
