This species was discovered at Tospam, near Cordoba, by 

 myself and Salle during our joint voyage in Mexico, and was 

 dedicated to me by Gould. 



It is this species which is abundant in the forests near 

 Tospam and elsewhere, and which perch on the low branches 

 of bushes near the srround. In the breadino- season the male 

 is perched near the nest of its mate and sings to her during 

 the best part of the day.

Type : T. pretrei, Less, and Delattre, Rev. ZooL, 1839, p. 20. 



Bill much longer than the head, slightly curved, broad at 

 base and rather stout, terminating in a sharp point. Wings 

 moderately long reaching between the second and third lateral 

 rectrices. Outermost rectrice very short, the next slightly 

 longer, the third longer, the fourth six-eighths of an inch 

 longer with elongated round tips, the medians also six-eighths 

 of an inch longer than the fourth. The length of the third, 

 fourth and median rectrices distinguishes this genus from the 

 preceding ones. Nostrils exposed. 



Habitat. — Brazil, Venezuela and Columbia.
