Makusian

The Makusians were a humanoid race from Makus III, characterised by their tall stature, dark brown skin and wing-like, back-swept ears. They were known for their friendly, open warmth when interacting with others. 

In 2267, Makusian ambassadors travelled aboard the USS Enterprise (NCC-1701) to attend the Babel Conferences.

Background
In his annotations, Christopher L. Bennett, the author of Forgotten History, had this to say about the aliens seen in Journey to Babel:
 * I have assumed that Makus III (the destination of the medical supplies in "The Galileo Seven") is the homeworld of the tall, dark-skinned, robed and hooded ambassadors seen in the same episode.
