History and Synonymy

Rimella tyleri in Schepman, 1909, pl. XV, fig. 5 a, b

  • Description of the radula of Rimella tyleri by Schepman, 1909, p. 156:
    • ”The radula which, as far as I am aware, was not yet known is very small, its length is about ¾, its breath 1/3 of a Mill., with about 35 transverse rows. The rhachidian tooth ® is broadly rounded in front, contracted behind, with a cusp bearing one moderately large central denticle and about 6 smaller ones on each side, the laterals (1) are strongly transversely elongate with a simple reflected margin, terminating in a sharp point towards the centre of the radula, the uncini (U) are long and slender, strongly curved, with a few indistinct denticles. The general appearance of the radula is much the same as that of the preceding genus, as far as may be judged from one radula of each, the chief difference being the smooth margin of the laterals, which are provided with many denticles in Rostellaria."
