''Haliotis jacnensis'', common name : the Jacna abalone, is a species of sea snail, a marine gastropod mollusk in the family Haliotidae, the abalones. ;Subspecies: * ''Haliotis jacnensis jacnensis'' Reeve, 1846 * ''Haliotis jacnensis kershawi'' Owen, 2012 ==Description== The shell size varies between 7 mm and 25 mm. The oblong-ovate shell is spirally peculiarly rudely ridged. The ridges are very irregular and rather scaly, somewhat smooth next the perforations which are slightly tubiferous and distant. The coloration is reddish-orange. The interior surface is silvery. This is a very characteristic species, to which there is little or no approximation in any other.〔(H.A.
