The fluctuation specific heat above transition for a clean superconductor in a uniform magnetic field is calculated microscopically for fixed temperature and varying field. It does not exhibit the premature breakdown of the Ginzburg-Landau approximation, arising from failure of the ( del/i)/sup 2/ ..-->.. ( del/i + 2eA/ h-barc)/sup 2/ substitution that was found previously for the clean fluctuation diamagnetism. (AIP)
