Comanche borrowings?

[Rory M Larson]

Has anybody noticed that the Comanche word for 'black bear'
is wasape?  (Comanche Vocabulary. Manuel Garcia Rejon,
tr. & ed. Daniel J. Gelo, University of Texas Press, Austin,
1995.)  I assume that's a loan from Dhegihan, probably
Ponka if not Kaw or Osage.

Also, they seem to have three words for 'horse':
puki, tIhIya and kobi.  Kobi seems to mean 'mustang'
or 'stallion'; is this another variant of caballo/kawa?
