Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the definition of a "catalogue" in the context of biological classification.

2. **Defining a Catalogue**: A catalogue is essentially a list or register that includes the names of all species found in a specific location. It organizes these names, often in alphabetical order, making it easier to reference and identify different species.

3. **Analyzing the Options**:
- **Option A**: "The list or register containing names of all the species found in a particular place." This aligns perfectly with the definition of a catalogue.
- **Option B**: "The booklet containing all characters and their alternates which are helpful in identifying all the taxa." This describes a taxonomic key, not a catalogue.
- **Option C**: "A handy book containing instruction of a species." This refers to a manual, which is not a catalogue.
- **Option D**: "A treatise having all information about a particular taxon." This describes a monograph, not a catalogue.

4. **Conclusion**: Based on the definitions and the analysis of the options, the correct answer is **Option A**: "The list or register containing names of all the species found in a particular place."
