Georissa semisculpta Godwin Austen & Nevill, 1879
“A single mature specimen, with the spire unfortunately broken, was found by Dr. Townsend in the Buket Pondong cave in Perak. It differs so conspicuously from every other known species, and would be so easily recognized again, that I have not hesitated to describe it, though I do not usually do so when I possess only a unique specimen. The figure is perfect.” (Godwin-Austen & Nevill, 1879)
“Mixed with the G. monterosatiana from Bukit Chintamani was another abundant species which I identify as their semisculpta. Fresh specimens are of a warm red colour and have fine raised spiral ribs which are distantly and somewhat irregularly spaced and vary a good deal in degree. The suture is deeper than in monterosatiana. The sculpture is very fugitive.” (Tomlin, 1944)
