My employer has decided to include a certain position emeritus on the letterhead, and so has come the question of the proper plural of "emeritus."

According to my Webster's unabridged,

emeritus...<Latin, past part. of emerere to obtain by service, to complete one's term, fr. e + merere to earn, serve one's term ...> 2: retired from an office or position esp after gaining public or professional recognition ... often used postpositively <professor ~> and sometimes converted to emeriti after a plural substantive <professors emeriti>

My first impulse was to say that the plural of emeritus was emeriti, but that use of sometimes in the definition gave me pause. So, I thought I'd ask you latin scholars. Would you indicate two Chief Judges emeritus as Chief Judges Emeriti?
