1864.] ON A COLLECTION OF BIRDS FROM PANAMA. 357 
pt. 3 (P. Z.S. 1858, p. 274). Mr. Lawrence has evidently mistaken 
the female for another species.

Ll. e. vil. p. 325. 
A single female of this species.

plumbea; abdomine dorso concolore, 
Hab. In isthmo Panama. 
Several specimens of both sexes of this species are in the collection. 
Mr. Lawrence appears to have referred it to Sclater’s M. exul; but 
that species has wing-coverts distinctly spotted with white, and is 
smaller in size.

A single example of this species, originally described by Lafres- 
naye from this locality.

P. leucaspis, Lawr. (nec Scl.) vii. p. 326.

One male example of this fine species. 
113. Formicarius HOFFMANN, Cab. Journ. f. Orn. 1861, p. 95, 
Several examples of this species, which is well described by Cabanis, 
l.c., are in the collection. According to Mr. Lawrence, F. analis 
appears also to occur; this species is more like F’. moniliger, except 
in the red crissum. 
114, Prrrisoma MIcHLERT, Cassin ; Lawr. /. c.vii. pp. 294 & 326. 
Several examples of this fine Ant-thrush are in the series. The 
form hardly differs from that of the larger Grallarie, except in the 
broader and rather flatter bill. =
