362 Mr. P. L. Sclater on the Fissirostral family Bucconidae. 



cemcali torque pallide fulvescenti-albis ; capitis lateribus 

 pectore et ventris lateribus lineis nigris transversim radiatis : 

 loris gula et ventre medio cum crisso albis : pedibus nigris : 

 rostro plumbeo. 



Long, tota 8*0 ; alse 3*4 ; caudse 3'0. 



Hab. in Nova Grenada. 



On first seeing this Bucco I took it for an immature state of 

 B. chacuru, but a more accurate examination has convinced me 

 that it is quite distinct. The present species may be at once di- 

 stinguished by its lead-coloui"ed bill and radiated under-plumage, 

 as well as by the entire absence of the large black blotches on each 

 side of the neck, which form one of the characteristic features 

 of the latter species. Of two examples in the British Museum, 

 one is labelled as having been received from Santa Fe di Bogota 

 in 1843. 



The upper plumage is clear ferruginous brown crossed with 

 regular black bars which are narrower on the head: on the neck 

 and upper back the feathers are nearly wholly black. The 

 under surface of the remiges is buff-coloured ; the inner web of 

 the apical half of the primaries is pure pale black. The rectrices 

 are uniform clear brown, paler below and regularly crossed by 

 seven or eight black bands.

This Bucco appears to range farther south than any other 

 species, being the only one included by Azara in his account of 

 the birds of Paraguay. Prince Maximilian of Neuwied says 

 that he " met with it in the bush and wood valleys of the
