Tediously lengthy list or speech (6)

Ross

I believe the answer is:

litany

(Other definitions for litany that I've seen before include "petitions" , "Long list (of requests or complaints)" , "Ceremonial form of prayer" , "Long and tedious series" , "A long monotonous recital as of complaints" .)

I've seen this clue in The Times.
