Georissa monterosatiana Godwin Austen & Nevill, 1879
“Another shell found in the same locality by Dr. Townsend. The sculpture and characters of the aperture are admirably represented by the figure; the last whorl but one, however, should be considerably more convex and consequently less turreted and less conspicuous; the base of the last whorl is a shade too convex, giving the shell an umbilicate appearance, which it does not possess.” (Godwin-Austen & Nevill, 1879)
