Here we're really talking about professional criminals of all sorts, especially those who were carefully organized in one fashion or another.
People

Types
THE SIXTY ORDERS OF PRIME COVES.
from Anon., “A Flash Dictionary,” Sinks of London Laid Open (J. Duncombe, 1848); at The Victorian Dictionary, which has the full text of the book. It’s not at all clear to me what if any reason informs the list order. Definitions for most if not all of these types may be found at the SlangDictionary. Note that shoplifters appear (#17 and #40), suggesting that this list may not be terribly carefully thought-out.
