I've been killing "a large snake" for a long time in BBM and Qeynos Catacombs. They do not drop "Large King Snake Skin" but rather "Large Snake Skin" from the ones in Butcherblock, and "King Snake Skin" from Qeynos Catacombs.
The only "Large King Snake Skin" is from "a Large King Snake" in Qeynos Hills.
Bummer...
