part of the skull, and disarticulating them from the pterygoids, 

 the bone which I suppose to be the vomer comes away with the 

 palatines, as would be expected, were such the case. 



The absence of truncation in the vomer of the Woodpeckers 

 tends by itself to remove them from a close relationship with 

 the Passerine birds ; but, as I before remarked, this peculiarity 

 may depend on their special habits. There is, however, in the 

 shape of the pterygoid bones a character which tends to bring them 

 together again. In Passerine birds the pterygoids extend for- 

 wards for a considerable distance in front of the point of contact 

 or articulation with the palatines. These antei'ior processes are 

 vertically expanded and in contact with the rostrum, and pro- 

 bably sometimes with the crura of the vomer ; they are situated 

 above (that is, deeper than) the posterior internal angles of the 

 palatines, and therefore are not seen while looking at the surface 

 of the palate, but only on a side view\ In the Woodpeckers and 

 other birds related to them these processes are also present, but 

 they are absent in most others, though the Anserine birds 

 possess them. In the Woodpeckers, also, there is a very peculiar 

 anteriorly directed process arising from the upper part of the 

 middle of the body of the pterygoid bone, which is quite inde- 

 pendent of the one above described. 



XLII. — On a Collection of Birds recently made by Mr. A. H. 

 Everett in JSorthern Borneo. By Arthur, Viscount Wal- 

 den, P.Z.S., F.R.S. 



(Plate XII.) 



Having lately had an opportunity of examining a small collection 

 of birds obtained in Northern Borneo by Mr. A. H. Everett, it has 

 occurred to me that a list of the species it included might form 

 an acceptable addition to our knowledge of the avifauna of that 

 island. Hitherto the Bornean collections sent to London by 

 Mr. Everett have been dispersed before being catalogued, and 

 the valuable materials he had contributed to the formation of a 

 complete list of North-Bornean birds were thus rendered un- 

 available. This is the more to be regretted, as most of his spe-
