Abstract:

This study described the taxonomic status of ‘Daru-daru’, T. sulcata and some morphometric characters of samples obtained from Toytoy, Caramoran and Palnab, Virac, Catanduanes. It was known that the samples from the said localities are just the same as the types described by previous taxonomists. Although there were some variations as to coloration, spire and whorl characteristics having flattened or pointed shell structures these were not significant enough to suspect possible ecotype that could exist in these collection areas. Moreover, as to some of the morphometric characters determined, the gastropod T. sulcata possesses variable sizes in total length and body width as well as live weights of the shells examined. The range of shell length was known to be within the range as described in extant literatures.
