Some authorities regard S. bartletti as a nomen dubium.

S. bartletti is known from only the holotype and six other specimens (all ) described by Tom Iredale in 1954. It is possibly a junior synonym of Sepia bandensis. The placement of S. bartletti in the genus Sepia is also questionable. Current Classification of Recent Cephalopoda

S. bartletti grows to a mantle length of 74 mm.

The type specimen was collected in the Misima and Conflict Group of the Louisiade Archipelago, to the southeast of Papua New Guinea. It is deposited at the Australian Museum in Sydney.
