__utma, __utmb, __utmc, __utmv, __utmz (Google Analytics cookies)
(Definition taken from http://helpful.knobs-dials.com/index.php/Utma,_utmb,_utmz_cookies)
The cookies named __utma through __utmz come from websites that use Google Analytics, which primarily uses it to track visits.
__utmz stores where a visitor came from (search engine, search keyword, link)
__utma stores each user's amount of visits, and the time of the first visit, the previous visit, and the current visit (presumably partly for double checking of this information).
__utmb and __utmc are used to check approximately how long you stay on a site: when a visit starts, and approximately ends (c expires quickly).
__utmv is used for user-custom variables in Analytics
__utmk - digest hashes of utm values
__utmx is used by Website Optimizer, when it is being used
