Sarika planata Laidlaw, 1933
“Closely related to S. limbata v. Molldrf. From Koh Tao. Compared with limbata the spire is even flatter than in that species, the last whorl is slightly more globose, and descends less. An example of limbata det. Tomlin, measurts. Breadth 13 mm. alt. max. 5.5 mm.” (Laidlaw, 1933)
Laidlaw (1933) original descriptions on Sarika planata – “Shell dextral, with flattened spire, the last whorl slightly descending. Colour rather dark brown, almost uniform. Whorls about five. Surface smooth, polished, marked with very numerous fine lines of growth. Scarcely perforate, suture well impressed.”
“Anatomy that characteristic of the genus. The penis has a long uncoiled coecum to which the retractor muscle is attached, it also bears a long spermatophore-sac which opens into it at the point where it is joined by the vas deferens. The receptaculum seminis has a long slender stalk, and the dart-sac is long and convoluted.” (Laidlaw, 1933)
“The radula bears a strong resemblance to that of other species of the genus. The formula is 49-10-1-10-49. the laterals are rather sharply marked off from the admedians, and the ectocone on the laterals and inner marginals is small and the laterals are long and slender. Limbata has a very similar formula 45-12-1-12-45, and a fairly close general likeness, but on the laterals and inner marginals the ectocone is much larger, equal to the mesocone, and the marginals are not so slender.” (Laidlaw, 1933)
Sarika planata – “Breadth 13 mm. alt. Max. 5 mm.” (Laidlaw, 1933)
Type locality – “Malay Peninsula; Tanah Rata, Cameron Highlands, Pahang, 4500 ft” (Laidlaw, 1933)
