This stiange-looking Barbet is the type of the genus Tetragonops : there is only one 
othei species, very different from it in colouring, T. frantzii. The first specimens were sent 
to England by Professor Jameson, from Quito, and others have since been obtained from 
Nanegal. It is a very rare bird, and nothing is known of its habits. 
There are two good figures of it extant, besides the one in this book — one in ‘ The 
Ibis ( l . c.), and the other in ‘The Edinburgh New Philosophical Journal’ ( l . c.). 
Our Plate was taken from two specimens in the collection of Mr. Salvin.
