1864.] | ON A COLLECTION OF BIRDS FROM PANAMA. 349 
37. CHLOROPHANES GUATEMALENSIS, Scl. P. Z.S. 1861, p. 129. 
C. atricapilla (Vieill.), Lawr. 7. c. 1861, p. 319. 
There appear to be four points by which the Central American 
Chlorophanes can be distinguished from the New Granadian, viz. by 
size (the northern bird being the larger), by the greater length of 
the bill, by the greater extent of the black crown, and by the greener 
east of the plumage. Specimens from Panama have the general 
coloration and long bill of the northern bird, but the smaller size and 
less extensive black crown of the southern. It is, in fact, in its cha- 
racters of so-called specific value, exactly intermediate between the 
two ; but for the present we prefer to leave the question open as to 
the propriety of maintaining the two, or perhaps three forms as 
distinct, or of uniting all under one variable species—at the same time 
noticing that specimens from the same locality present remarkable 
uniformity of size and coloration.

40. CeRTHIOLA MEXICANA, Sclater. 
C. luteola, Cab.; Lawr, J. c. 1861, p. 291. 
Panama specimens are quite identical with Guatemalan and Mexi- 
can examples, and are hardly separable from the New Granadian C. 
luteola. The whole genus requires a careful revision. 
Fam. TANAGRID. 
41. EuvpHontia CRAsstRostRIs, Sclater. 
Agrees with New Granadian and Ecuador specimens. It differs 
from the Mexican and Guatemalan LZ. hirundinacea in the more ex- 
tended yellow crown, and in having the white internal web of the 
outer rectrix not continuous to the end of the feather. Moreover 
the female is yellow instead of ashy beneath. 
42. EupHontiA FULVicRISSA, Sclater, P. Z.S. 1856, p. 276; Cat. 
Am. B. p. 58; Cassin, Proc. Acad. Phil. 1860, p. 143. 
Sclater’s original description only relates to the male of this very 
distinct Huphonia, of which the present collection contains two 
pairs. The species must be removed into the vicinity of #. gouldi, 
and may be shortly characterized as follows :— 
3. Supra nitenti-ceruleo-nigra, fronte anguste flava: subtus 
flava, gutture ad medium pectus dorso concolore : ventre medio 
erissoque fulvo-rufis, hoc saturatiore: rectrice una utrinque 
externa in pogonio interno alba. 
Q. Supra olivacea, eneo tincta: fronte anguste rufa: subtus 
olivaceo-flava, medialiter flavidior, crisso fulvescenti-flavo. 
The species ranges from Santa Martha up to Panama. Lieut.
