Trogon neoxenus, Gould in Proc. of Ziool. Soc. Part VI., 1838. 
I HAVE seldom been more gratified by tbe sight of any species of this beautiful family than I was on the 
receipt of the bird figured in the accompanying Plate, which exhibits characters of the highest interest, 
although the specimen (the only one I have seen) is evidently in a state of immaturity. Judging from analogy, 
I should conceive that it is the young male of an aberrant species of that splendid minor group, to which 
the sub-generic name of Calurus has been applied ; and that the adult, which is at present unknown, will, 
whenever it is discovered, prove to be a bird of very great beauty. The individual represented was received 
from Mexico by John Taylor, Esq., by whom it was presented to the Zoological Society of London. 
The difficulty of assigning a specific name to any species of which the young only has been seen, has 
induced me to propose that of neoxenus (welcome stranger) for the present bird, adult examples of which 
will be sought for with the highest Interest by every ornithologist.
