In the late 70s or early 80s there was a movie on HBO with a woman who was created in an aquarium as a baby and doberman pinchers. What was the title?

It's the 1976 movie Embryo with Rock Hudson, Barbara Carrera, Diane Ladd, and Roddy McDowall.

I am looking for title of two more movies. These movies are older, possibly 60s or 70s.
They are both horror flicks. The first one is about a hole in the ground on a family property. What I remember is a creepy moaning sound coming from the hole and people going into it and coming out like they saw something AWFUL. I remember the ground shaking and causing dishes to crash in a house. What is the title?
All I remember about the second movie is a hand in box.
I believe they are both black and white. Any help?

That is the Gate and the Hand
