The headquarters of this curious species seem to be Colombia, where it has been 

 noticed in several places. Specimens occur, but not very frequently, in the trade 

 collections made in the neighbourhood of Bogota, but the bird is more common in the 

 northern parts of the country. Within our region it has been observed by two collectors 

 — M'Leannan, who met with it on the line of the Panama Railway, and sent specimens 

 to Mr. Lawrence, in whose lists they appear as Todirostrum megacephalum * ; and Arce, 

 who sent us two male specimens from Santa Fe in the State of Panama *. Mr. C. J. 

 Wood says he met with this species near Carthagena, in the bushes and low trees, 

 constantly flying after insects, and uttering a single chirp, by which it could easily be 

 traced and shot ^. He frequently saw it in the month of April. Mr. Simons, who sent 

 us specimens from Minca in the Sierra Nevada of Santa Marta, says that the iris in life 

 is white, shading into brown or yellowish white ^. 



LEPTOTRICCUS.

LeptOtriccus, which was founded on the Brazilian L. sylviola, contains but two 

 species, that just named and L. superciliaris of the State of Panama. 



With a bill similar to that of Lophotriccus the rictal bristles appear to be longer, 

 there is no occipital crest, the 2nd, 3rd, 4th, and 5th quills are nearly equal, lst=8th, 

 the tail is long and very slightly rounded, and the feathers wider than in Todirostrum 

 nearly = wing, the tarsus = ^ wing.
