Other comments: Aeka is spoken by about 2,800 speakers in a region lying to the south of the Binandere area, Tamata Rural LLG of Oro Province, Papua New Guinea.

Aeka system displays a (2, 5) cyclic pattern with a frame pattern of (1, 2, 5) although this does no adequately describe the rather more complex construction of the numerals 6 to 9. The number word for 5 is 'ingeri tawo', i.e 'hand one'; similarly that for 10 is 'ingeri eoto' ie 'hands two'. Tallying proceeds from fingers to toes after 10 and we have the number word for 15 is 'ingeri eoto tei tawo', i.e 'hand two foot (or leg) one'. The number word for 20 is 'ingeri eoto tei eoto' or 'hands two feet (or legs) two'. As we have no data beyond 20 it is uncertain whether, as would be likely, the system possesses a super- ordinate 20-or 'man' cycle.
