Answer

To determine which snake is referred to as the "double-headed snake," let's analyze the options provided in the question step by step.

### Step 1: Analyze Typhols
- **Typhols** refers to a group of blind snakes that belong to the family Typholopidae.
- These snakes are not known for having a double-headed appearance.

### Step 2: Analyze Pataeus
- **Pataeus** are known as rat snakes and belong to the family Colubridae.
- Rat snakes do not exhibit a double-headed appearance either.

### Step 3: Analyze Eryx
- **Eryx** is a genus of non-venomous snakes, commonly known as sand boas or old world boas, and belongs to the family Boidae.
- The body of the Eryx is cylindrical, and its head is not distinctly separate from its neck. This can give the illusion of having two heads because the tail resembles the head shape.

### Step 4: Analyze Bungarus
- **Bungarus** refers to a genus of venomous snakes found in South and Southeast Asia, belonging to the family Elapidae.
- These snakes are not associated with a double-headed appearance.

### Conclusion
Based on the analysis, the snake that is commonly referred to as the "double-headed snake" is **Eryx**. The shape of its tail resembles its head, which contributes to this misconception.

### Final Answer
The correct answer is **Eryx**.
