have already figured*: these appear to pass into the 
ix subgenus Ramphopis (R. 
coccinea, fig. 166.), by means 
of Lamprotes: and here 
(unless Arremon forms the 
tenuirostral type of this di- 
vision) the genus Tanagra 
terminates. In all these 
foregoing types, the bill is 
more or less shorter, stronger, — 
and thicker, than in the 
next genus, Phenisoma, which seems to be chiefly 
distinguished from all the subgenera of the last, or 
_ Tanagra, by a much more lengthened and a more slen- 
der bill. We enter Phenisoma by the very singular 
form, now first named Lamprotes ; its long wings, short 
feet, and glossy plumage, seem to point it out as a 
fissirostral type, while the short and soft frontal feathers 
remind us of Ramphopis. After this, we place the 
Phenisome proper, or the red birds, many of which 
have long wings, and all, like Lamprotes, have the bill 
lengthened: from these to Tachyphonus, the passage is 
very gradual. Tachyphonus is chiefly distinguished by 
its lengthened conic bill, compressed on the sides, and 
often distinctly festooned in the middle of the upper 
mandible. The genus ZLanio of Vieillot is obviously 
only a typical species of this subgenus, and we, therefore, 
do not adopt it: in the aberrant species, such as 7". niger- 
: E rima, andzsome others, this 
festoon disappears; and we 
are thus prepared for Leuco- 
pygia, a new subgenus, cha~ 
racterised by having the bill 
short, much compressed, and 
quite entire( fig.167. a). It is 
by this form, altogether pecu- 
eS liar from itsentire bill, that we 
suspect the Sern Passi passes into the next. Such
