Hello everybody,
 
yes, there are at least three. In older literature there are 4. Tyleri is
the most difficult to get. The other one I never saw is speciosa H. & A.
Adams.
 
Tryon (1885):
 
 
"Shell reticulated, more lanceolate than R. cancellata, not ending
atneriorly in a recurved beak, with the varix of the outer lip plain
externally, and with the posterior canal of the aperture faintly devloped
and only extending as far as the penultimate whorl. Length, 1 inch.
Hab unknown. Unfigured. Is it R. crispata ?  "
 
For tyleri H. & A. Adams,
 
he writes:
 
"Cancellated, posterior canal extending to the third whorl and curved,
outer lip corrugately plicate within, with an anterior, conspicuous, sharp
tooth; yellowish with four chestnut bands. Length, 21 mill. Unfigured.
China Sea"
