"T. rubicundits Chemnitz" of authors is a synonym. 



This species was first figured by Chemnitz in 1781 under the des- 

 criptive name of cochlea lioiaris ruhicunda granosa etc. Reeve in 

 his Conch. Syst. figures the shell, naming it T. rubicnndus, and re- 

 ferring to P. Z. S., 1842, for description. His reference has been 

 copied by subsequent authors, but curiously enough, the species is 

 not even mentioned in the "Proceedings," for 1842 or any other year. 

 Martyn's figure is excellent, and being the first publication of the 

 species under a binominal name, has been here adopted.
