Haliotis alfredensis is a species of sea snail in the family Haliotidae, the abalones.[1] It is known commonly as Port Alfred's abalone.[2] It is endemic to the waters off South Africa.[3]

Description

The holotype was 55 by 39.5 millimeters long and 12 millimeters thick. The shell is an elongated oval with chestnut brown mottling and pale olive flecks. The sculpture has radiating, slanting threads on the whorlss, which are fine, becoming coarser on the last turn. The spiraling lira become less wavy toward the anterior side. The nacre is pinkish inside and more red in the spire. The spiral sculpture is visible on the inside. The shell is similar in shape to that of Haliotis midae, but without the rugose sculpture; the sculpture is more like that of Haliotis rugosa rugosa, but finer and more regular.[4]
