Cox Plate runner-up Hartnell heads a strong team from Godolphin left in the Melbourne Cup at the latest declaration stage.
Trained by John O'Shea, Hartnell could be joined by stablemate Tally in the Cup (3200m) on November 1 with another five horses from the northern hemisphere arm of Sheikh Mohammed's global operation still in contention.
There were 32 horses left when second acceptances were taken on Monday with Saturday's Lexus Stakes, in which Tally is entered, the last chance to earn a guaranteed start.
Caulfield Cup runner-up Scottish and Geelong Cup first and third , Qewy and Oceanographer, remain in the entries for English Godolphin trainer Charlie Appleby while the Saeed bin Suroor stable has Secret Number and Beautiful Romance.
Hartnell, who finished eight lengths second to Winx in Saturday's Cox Plate (2000m), is the $4.60 favourite in the TAB's latest Cup market ahead of Caulfield Cup winner Jameka at $6.
