Ah yes,
B. c. longicauda, aka Peruvian long-tailed boa, aka Peruvian black-tailed boa, aka Tumbes boa.
Price will depend on bloodline, as well as the time of year. Right now, longi's are few and far between, so the prices are going to be a bit higher. Early in the season, they can be had for as little as $250.
As juveniles, they can be a bit more "delicate" than BCI. In my experience, they need to be raised in a manner similar to BCC- with a little more care taken to prevent regurgitations.
