what is wrong with the security updates?

[Pollywog <pollywog@shadypond.com>]

I downloaded the security updates from debian.org and when i tried to install
them, I got:

lilypad:/home/pollywog# dpkg -i netstd_3.07-2hamm.4_i386.deb 
dpkg-deb: `netstd_3.07-2hamm.4_i386.deb' is not a debian format archive
dpkg: error processing netstd_3.07-2hamm.4_i386.deb (--install):
 subprocess dpkg-deb --control returned error exit status 2
Errors were encountered while processing:
 netstd_3.07-2hamm.4_i386.deb

Are these not ordinary deb archives?
