need help with id of Flufftail sp.

These pictures are not the greatest but any suggestions as to species of Flufftail this is would be appreciated. Bird is currently frozen as I plan to take it to Dept. of Ornithology at the Nairobi Museum. It was found dead at Kijabe (altitude c. 2,200 m).

Pictures don't show it very well but the throat is clearly white. Tail not strongly barred.

Much appreciated,

Jeff Davis
