Dorsey Ddh in Biloxi

[R. Rankin]

He only writes ddh occasionally in Biloxi, but he
writes it all the time in Quapaw for the local reflex
of Proto-Siouan /r/.  What I heard for this in the
1970's was just a lamino-dental voiced stop.  I write
it simply as /d/.  I've never heard an actual fricative
offglide.                       Bob
