"T. rubicund us Chemnitz" of authors is a synonym. 



This species was first figured by Chemnitz in 17*1 under ti 

 criptive name of cochlea liniari* rubicwnda rjnnw^i olc. Kerve in 

 his Condi, tyst. figures the shell, naming it T. rnl.'n-nniln*, an, 

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

 copied by subsequent authors, but curiously enough, the speei 

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

 Murtyn's figure is excellent, and being the first publication "f the 

 species under a binominal name, has been here adopted.
