The former express 5 by _ghomen apa_, 1 man,[115] and the latter by _ibicho_, person.[116] The Tasmanians of Oyster Bay use the native word of similar meaning, _puggana_, man,[117] for 5.

This form of numeration is usually, though not always, carried as far as the system extends; and it sometimes leads to curious terms, of which a single illustration will suffice.

The San Blas Indians, like almost all the other Central and South American tribes, count by digit numerals, and form their twenties as follows:[118] 20.

tula guena = man 1.
40.

tula pogua = man 2.
100.
