To determine which of the following is not a member of Eutheria, we need to understand what Eutheria is and the characteristics of the animals listed in the options.

### Step-by-Step Solution:

1. **Understanding Eutheria**:
- Eutheria refers to a clade of mammals known as placental mammals. These mammals give birth to live young that have developed inside the uterus, nourished through a placenta.

2. **Analyzing the Options**:
- **Gorilla**: Gorillas are primates and are classified as placental mammals. Therefore, they belong to Eutheria.
- **Pangolin**: Pangolins are also placental mammals, belonging to the order Pholidota. Thus, they are part of Eutheria.
- **Mole**: Moles are small burrowing mammals that are also classified as placental mammals. Hence, they belong to Eutheria.
- **Platypus**: The platypus is a unique mammal that lays eggs instead of giving birth to live young. It belongs to the group known as monotremes, which are part of the subclass Prototheria.

3. **Conclusion**:
- Since the question asks for the option that is not a member of Eutheria, we identify that the platypus is the only one among the options that does not belong to Eutheria. Therefore, the correct answer is **platypus**.

### Final Answer:
