A type of 'Corydoras duplicareus' (Catfish)
The small fish collection (ca. 2,400 specimens) is worldwide in scope but has poor taxonomic coverage for any particular geographical area.
There are a few zoological types from the challenger expedition and some recent catfish types from South America. Another notable collection is the set of tumerous fish assembled by James Johnstone at the University of Liverpool in the 1920s. Early collections of this type from the Irish Sea are rare.
Most of the fish are in spirit, but a few are dried, and there are some skeletons. In addition there are about 60 model fish.
