of the existence of this species in Ecuador, Peru, or Bolivia. It thus appears that its 

 range hangs to the northern and eastern portions of South America rather than to the 

 western.

Hab. PAifAMA, Line of Eailway {MJ'Leannan & Galhraith ^ ^). 



This bird differs in many respects from P. lictor, which is also found on the Isthmus 

 of Panama. It has a shorter stouter bill, the crest is wholly yellow without any 

 admixture of orange, the back is more olivaceous, and neither the rump nor the 

 margins of the wings above or below have any chestnut colour. 



The bird also somewhat resembles in general colour Myiozetetes cayennensis, but 

 that species, besides its smaller bill with its curved culmen, has an orange crest, and the 

 edges of the wing-feathers inside and out are, like those of Pitangus lictor, chestnut. 



We have recently had an opportunity of examining Mr. Lawrence's type, which is the 

 only specimen we have seen. It was contained in one of M'Leannan and Galbraith's 

 collections made on the line of the Panama Eailway. 



So like is P. albovittatus in general colour to M. cayennensis and P. lictor that its 

 apparent rarity may be due to its having been mistaken by collectors for one or other 

 of those birds. 



SIEYSTES. 



Sirystes, Cabanis & Heine, Mus. Hein. ii. p. 75 (1859) (type S. sibilator) ; Scl. Cat. Birds Brit. 

 Mus. xiv. p. 181. 



Sirystes contains three rather closely allied though sufficiently defined species, whereof 

 S. albogriseus is alone found in the State of Panama, S. albocinereus in the Amazons 

 valley, and S. sibilator in Eastern Brazil. In coloration they somewhat resemble the 

 Antillean species oi Pitangus, but are destitute of the occipital crest. 



In many respects Sirystes resembles Pitangus, but the bill is not nearly so strong 

 and is wider in proportion to its length, the width at the gape being half the length of 

 the tomia, the sides are slightly concave, the supranasal feathers cover the nostril and 

 the rictal bristles are strong ; the tarsi and feet are more feeble than in Pitangus ; the 

 2nd, 3rd, and 4th quills are longest, 1st = 7th ; the tail is rather long = | wing, tarsus
