PACHYCEPHALA VANDEPOLLT, 225 



grey, without any rufescente, moreover larger. P. Plateni 

 Bias. (= Whiteheadi Sh.) from Palawan is of a darker 

 grey on the chin, throat and breast, has the head above uni- 

 form dark brown the same as the back, and is a smaller bird. 

 The nearest allied species, P. hrunneicauda (Salvad.) from 

 Sumatra, not represented in the Leyden Museum, has, ac- 

 cording to Salvadori's description, the tail «more reddish" 

 and is also considerably smaller, as shown by the sub- 

 joined measurements. 



2. Geoffroyus Lansbergei, n. sp. 



General appearence like a young individual of G, per- 

 sonatus (Shaw): upper parts, wings and tail dark green, 

 underneath yellowish green ; lores and fore part of cheeks 

 dirty brownish; under wing-coverts dark marine blue, but 

 distinguished in having the feathers of the upper parts 

 marked with a narrow light brown crossbar in the centre 

 and therefore mostly hidden ; the primaries show one , the 

 secondaries two obsolete dark crossbars at the end portion, 

 more distinct on the inner web and forming on the hind 

 secondaries (tertiaries) several dark crossbars over both 

 webs. — Bill light horn coloured. 



Al. 140 mm,; caud. 50 mm.; culm. 18 mm. 



Hab. Sumbawa. 



The single specimen was collected in October 1879 on 

 the Island Sumbawa and presented to the Museum by the 

 Governor-General van Lansberge, to whom the Museum 

 ows so many rare species. 



The bird is no doubt a young one, and most likely a 

 curious variety, which nevertheless deserves naming.
