Haven't we already been through this on here with this snake?
These new pictures suggest a black king - here's why -
1. The head shape says nigrita, not milksnake.
2. The brown hint to the background color. Many nigrita are actually dark brownish black, not glossy jet black. Black milks are glossy blue black.
3. A black milk under about 4 feet will show remnants of pattern generally, particularly on the side of the face.
4. Are there any white spots under the throat? Many (but not all) nigrita will have a white spot under the chin somewhere that you never see in adult milksnakes.
