A single specimen of Holothuria (Thymiosycia) arenicola Semper of 200 mm in length was collected on 19-5- '93 from east of the Van Island (Gulf of Mannar) from a depth of two metres. It is a tropicopolltan species. In the extended condition the body is slender and vermiform. The mouth is small and surrounded by tentacles which are ventral in position. On the dorsal side there are a few papillae. The pedicels are small and not conspicuous. On the ventral side they are arranged in three bands. The mid-ventral band is not distinct. In the other bands there are three or four pedicels in a row. Anus is terminal and surrounded by five groups of four papillae. In the living condition the colour is white. The dorsal side is scattered with very small brown dots which are not conspicuous. The ventral side is uniformly white. This is a fossorial form. The pedicels and papillae are highly reduced and therefore the burrowing is effected only by the contraction of the body muscles.
