We report the spectral lag analysis for GRB 111026A (GCN Circ. 12497) 
based on the BAT data.  Using 64 ms binned light curves, the spectral 
lag for 15-25 keV to 50-100 keV is 27 +32/-40 msec.  This value
is not very constraining towards the shortness of this burst.  
And further, the fact that the burst is longer in the 15-25 keV band
that in the higher energy band argues for a long burst assignment.
