There must be at least a half-dozen different manufacturers of that style  of 
oil filter canister and they all have springs, but in the upper part of the  
assembly, not down in the metal canister, so don't think that you've lost  
something. Depending on the type of canister you have, you may see a round disc  
at the bottom of the can. This is backed up by a spacer of some sort in most  
designs. The disc seals the bottom of the filter. The spring is behind  the 
disc that meets the filter at the top, or housing, end of the assembly.  If you 
press up on that disc, you will feel the resistance. When the filter  is in 
place and you tighten the through-bolt, that captive spring applies  pressure to 
the filter and seals the assembly.
 
Both the old filter and the new filter are "correct." They are just  from 
different manufacturers. I assume you know about the seal that goes  into the 
groove in the filter housing. It can be a pain to  extract.
 
Hope this helps,
