for my own devices here is my xtended list and sources compendium:
In it there are the instruments: bisernica, two brača (brothers - first and second bass), contra and berda (bass).
{{ }}
{{ The prim (prím) - one double string, E, and three single strings B, F#, C#. This is the smallest tamburica (about 50 cm long), but is very loud. It is mostly used as a lead instrument or harmonising instrument. }}
The bisernica (from Serbian and Croatian "biser" meaning "pearl") is almost identical but may have two double strings and two single strings.
The brač or basprim (brács or basszprím) - three double strings, or two double strings and three single strings (basprim), a slightly bigger, lower instrument than the bisernica but played in a similar fashion.
The čelović - originally two double strings and two single strings; now four single strings are more common.
The bugarija or kontra (brácsó or kontra) - one double string D and three single strings, similar to a guitar, mostly plays chords on the "back beat" for rhythm. A bugarija has five strings, the bottom pair are D, the middle string is A and the top two are tuned F# and F#.
The čelo (cselló) - four strings, similar in size to the bugarija and plays a counterpoint line which is usually improvised.
The bas or berda (tamburabőgő), also called begeš (bőgős) - four strings. It is the largest instrument in the tamburica family, and is similar to contrabass. It can only be played standing and is used for playing bass lines.
prim/bisernica one double string/two double strings smallest
{{brača/basprim/brac three double strings slightly bigger than bisernica, second smallest }}
contra/bugarija/kontra one double string guitar-like
celo/cselló/čelović four single strings. earlier: two double strings/two single strings
berda/bass/bas/begeš four strings largest contrabasslike
{{bisernica, brac, bugarija, celo and berde. }}
