11. Notes on A CoLLecTION or Birps FROM THE ISTHMUS OF 
Panama. By P. L. Scuater, M.A., Pa.D., F.R.S., ann 
Ossert SAtvin, M.A., F.Z.S. 
(Plate XXX.) 
The series of birds which forms the subject of the present paper 
was collected by Mr. James M‘Leannan, the track-master of Lion 
Hill Station on the Panama Railway. Lion Hill is the second station 
on leaving Colon or Aspinwall, and is about ten miles from the 
Atlantic coast of the isthmus. Mr. M‘Leannan is well known to 
science, having supplied Mr. G. N. Lawrence, of New York, with ma- 
terials for his valuable papers on the avifauna of the isthmus, pub- 
lished in the ‘Annals of the Lyceum of Natural History of New 
York,’ in the ‘ Proceedings of the Academy of Sciences of Phila- 
delphia,’ and in the ‘Ibis,’ where some few of the new species are 
described. The large series of birds possessed by us from countries 
immediately contiguous to the Isthmus of Panama, embracing many 
types of original descriptions, has enabled us to compare the Isthmian 
series with the birds of New Granada and Western Ecuador in the 
south, and with those of Guatemala and Southern Mexico in the 
north, necessitating in several cases an alteration of Mr. Lawrence’s 
nomenclature. This is our reason for retraversing the ground that 
he has already gone over so recently. 
The first indications of the rich avifauna of Panama were obtained 
by the well-known French collector, Delattre, who spent some time 
upon the isthmus when he visited New Granada and Bolivia in 1846, 
M. De Lafresnaye, who has given us an account of M. Delattre’s col- 
lections made during this expedition*, in the ‘ Revue Zoologique’ 
for 1847, mentions the following six species from Panama :— 
Conopophaga nevioides, Lafr. 
Pipra vitellina, Gould. 
Aglaia francesca, Lafr. 
Arremon aurantiirostris, Lafr. 
Coccoborus cyanoides, Lafr. 
Malacoptila panamensis, Lafr. 
Little further appears to have been done towards rendering our 
knowledge of Panama birds more complete until 1861, when Mr. 
Lawrence commenced the series of papers to which we have already 
alluded, upon the collections made by Mr, M‘Leannant. 
We yet require more perfect knowledge of the immediately adjoin-
