A syllabary devised for the Mende language in the early 20th century. It is written right to left. It is still in use but not yet encoded in Unicode.
According to Omnigator, it is "Used in southern and eastern Sierra Leone, originally primarily for translations of the Quran. The first 42 characters of the script work as an abugida, but the remaining 150+ form a syllabary. Tuchscherer reports that it is still in use by about 100 people."
