The Bristol side batted first and were grateful to opener Tim Hancock, whose 43 proved the bedrock of their innings.
Chris Day was the most dangerous Lansdown bowler, taking 3-23, with two wickets each for Jordan Price and Matt Thomas.
Bishopston did enough to tie down the visitors' reply. Wickets fell at a steady rate and, despite tidy middle-order knocks from Reece Croker (26) and Sam Athey (27), Lansdown were skittled for 128 with just one over remaining.
