Dyakia intradentata Godwin Austen, 1891
“Having seen but one specimen, I at first thought that this shell was only a reversed variety of D. hugonis, and that the depression was the result of some injury. I now find that Dr. Hungerford has two specimens, and a young shell in Mr. Everett's collection from the Niah Hills is evidently of the same species.” (Godwin-Austen, 1891)
Godwin-Austen (1891) original descriptions on Dyakia intradentata – “Shell very similar to D. hugonis in form and coloration, more acute in the spire and rather flatter on the base, with the umbilical region more excavated. The whorls more closely wound. Sculpture coarser and more decussate, that on the lower side finely papillate. Looked at from below there is a very remarkable dent or small depression indicating the presence of an internal tooth, and this is situated at the distance of exactly half a whorl from the aperture.”
