Plural of buly or bulie; a type of small South American fish, or obsolete plural of bully.
From Spanish or Portuguese 'buly,' of uncertain origin, possibly from indigenous languages of South America where these fish are found. This is a rare ichthyological term.
This word is so obscure that it appears in almost no modern dictionaries—it's the kind of specialized term ichthyologists would use for small tropical fish species!
