Assiminea woodmasoniana Nevill, 1880
Brandt (1974) descriptions on Assiminea (Assiminea) woodmasoniana – “Shell elongately conic, the most elongate species of the genus. Brownish or straw-coloured, glossy, with very delicate spiral microsculpture. About halfway between the suture and the periphery there is a distinct spiral thread; another spiral thread encircled the closed umbilicus. The 7 whorls are almost flat and increase regularly in diameter. Body whorl angulate in young shells but well rounded in adult ones. Aperture pyriform, with pointed top and well rounded base. Peristome continuous, columellar straight, thick and flattened. Operculum typical.”
“Radula with squarish rhachis which has at the base a long, handle-like process. The cutting edge has 5 cusps. There are 2 diagonically placed basal cusps on either side. The laterals have the formula 3-1-2, the inner marginals have 7 cusps, the outer about 20. The examined specimen had 53 rows of teeth but only 34 rows showed well developed teeth.” (Brandt, 1974)
