I would try somthing like:

for file in `ls -1 snort.log.1221*`
do
  echo $file
  tshark -r $file -w tmp-$file -R "ip.addr==10.10.2.4"
done
mergecap -w test_0918.pcap tmp-snort.log.1221*
rm -f tmp-snort.log.1221*

Thanks, Sake - that works great. 
 
Out of curiosity:  Was there something wrong with the way I did it, or is this a bug in TShark?
 
Thanks again,
JB
