PANAMA. 
By DAVID 8S. JORDAN. 
Four hundred and seven species of fishes are now known to inhabit 
the waters of the Pacific coast of tropical America between Cape San 
Lueas and Panama. Our knowledge of these species is due chiefly to 
the studies of Dr. Gill, Dr. Giinther, Dr. Steindachner, and Professors 
Jordan aud Gilbert. Only a few collectors have given especial atten- 
tion to the fish fauna of this region, but the work of these has in nearly 
all cases been of exceptional value. 
The earliest extensive collections were made by Mr. John Xantus at 
Cape San Lucas, and later at Colima. The specimens obtained by 
Xantus comprise especially the fishes of the rock-pools. These were 
studied by Dr. Gill in 1862, and by Professor Gilbert and the writer in 
1882. Many of the specimens collected by Xantus still remain unique. 
The next collections were made in the bay of Panama, by Capt. John 
M. Dow, about 1862 to 1866. The first of these were sent to the Smith- 
sonian Institution, where they were studied by Dr. Gill. Later, still
