You didn't post a picture or link anything. :P
No photo attached...
Thats an oldman cactus which could actually be one of several different species.
Here is a link that might be useful: https://www.google.com/search?q=oldman+cactus&tbm=isch&tbo=u&source=univ&sa=X&ei=JMHqU5C9CoW8igKhroDQBA&ved=0CCgQsAQ&biw=1536&bih=747
looks like a Mammillaria... possibly plumosa or hahniana.
