* This species, like M. cafenata, was by early English writers errone- 

 ously referred to the British Seas, but its true habitat is now well known. 



f Hanley, in his Ipsa Linnaei Conchylia, has well shown that none of the 

 Linnaean references can be applied to Donovan's M. pallida. 



X In cases of doubtful priority like this, the author who publishes U77/i- 

 out date is justly placed after the one who dates.
