Privacy Services provide the Registrant's Name, but the Privacy Service's contact information. The Privacy Service passes on  non-spam messages to the Registrant, particularly legal notices, acting as a type of “registered agent.”

Proxy Services register the domain name and license it to another for use.  

Privacy services limit certain user details from WHOIS by offering alternate contact information and mail forwarding services, while not actually shielding the user’s identity.

Proxy services have a third-party register domain names on the user’s behalf and then license the use of the domain name so that a third-party’s contact information (and not the licensee’s) is published in WHOIS.
