64. POMADASIS HUMILIS. 
Pristipoma humile Kner & Steindachner, Sitzgber. Aina. Wana, (Miinch. ), 1863, 222 (Rio 
Bayano, near Panama). 
Habitat: Pacific coast of Central America, often or always in fresh 
waters. 
Etymology: Humilis, humble. 
This species is known from a few specimens, all taken from the Rio 
Bayano, near Panama. The two examined by us (30957) were taken by 
Capt. John M. Dow. In the same bottle was a specimen of Joturus 
pichardi (type of Joturus stipes), which is a strictly fresh-water species.
