INTRODUCTION. 
Cabanis and Heine to be properly separable; and for it they proposed the name Septuas 
in the ‘Museum Heineanum’ (iv. p. 206). Of this scarce species two specimens, an 
adult and a young bird exist in the Berlin Museum, besides those mentioned in this work. 
The following additional remarks on species are necessary, in order to include the 
observations of ornithologists which have been published during the progress of the present 
work through the press. 
PHAROMACRUS. 
P. MOCINNO. 
Since the text accompanying the Plate of this species was written, I have noticed 
that Bonaparte in his ‘ Conspectus Volucrum Zygodactylorum,’ p. 14, adopts the specific 
name mocinno, thus furnishing further evidence in favour of the priority of that name 
over his title of paradiseus. 
P. AURICEPS. 
A name (P. heliactin ) has been proposed by Messrs. Cabanis and Heine (Mus. Hein, 
iv. p. 207) for the Ecuadorean race of P. auriceps. It is stated to be smaller than 
the more northern bird, but not otherwise different. As specimens from Antioquia are 
intermediate in size, and as size alone is a specific character of very doubtful value, 
I think that the Ecuadorean bird had best be considered merely a race of P. auriceps 
and not a true species. In like manner the P. xanthog aster described by Counts Turati 
and Salvadori (P. Z. S. 1874, p. 652), I have little doubt, is a variety of P. auriceps, but 
of interest when the relationship of T. aurantiiventris to T. puella is considered. 
TROGON. 
T. CALIGATUS. 
To the synonymy of this species the name T. concinnus must be added; this name 
was proposed by Mr. Lawrence for a bird from Panama which must certainly be considered 
a young male of T. caligatus.
