INTRODUCTION. 
The fifth section contains the Hill Toucans, forming my genus 
ANDIGrENA, 
WITH THE FOLLOWING CHARACTERS 
Rostrum turgiclum, magnum, attamen minus quam in genere restricto Pteroglossus dicto. Alee et caudce ut in genere 
Aulacorampho nominato. Ptiluma elongatnm, laxum, capillaceum. 
Bill stout and swollen, but not so large as in the true Pteroglossi ; wings and tail very similar to those of Aulaco- 
ramphus; general plumage long, loose, and hair-like. 
It has been found that even the higher ranges of the Andes are not untenanted by the Toucans ; 
Professor Jameson of Quito informs me that the A. laminirostris even ascends the sides of Pichincha to an 
elevation of from six to ten thousand feet. The members of this genus extend all along the Andes and the 
Cordilleras, from the Caraccas to Bolivia, where Mr. Bridges found a species in the forests of Cocapata, in 
the department of Cochabamba ; one species, however, the A. Bailloni, appears never to quit the lowlands of 
Brazil. These Hill Toucans have stout hard bills, 
generally of a uniform and delicate colour. 
The species are— 
37. Andigena laminirostris 
38. 
-hypoglaucus 
39. 
-uigrirostris . 
40. 
cucullatus 
41. 
-Bailloni 
are very thickly clothed, and have the under surface 
PI. XXXVII. 
PI. XXXVIII. 
PI. XXXIX. 
PI. XL. 
PI. XLI. 
The sixth and last section comprises a series of birds remarkable for some of the species having the 
sides of their bills deeply grooved ; they form my genus 
AULACORAMPHUS, 
WITH THE FOLLOWING CHARACTERS 
Rostrum, comparative breve, latum, ad culmen depressum; apud latera sulcatum; mandibulti inferiore ad basin 
oblique ultra oculi lineam tendente; alee breves et rotundatae, remige quarta longissima, quinta, sexta, et
