"英属西印度群岛" can be translated as "British West Indies".
This term historically referred to the British colonies and dependencies in the Caribbean region. While some of these territories have since gained independence, the term "British West Indies" is still occasionally used, especially in historical or cultural contexts.
For more specific references to current or former British territories in the Caribbean, one might also use terms like "the British Caribbean" or mention individual countries or islands that were part of the British West Indies, such as Jamaica, Barbados, Trinidad and Tobago, etc.
