as claimed by Hupe, and admitted by Pfeiffer, who states that 

 Hupe's shell is different from tbejugsieui of his previous description 

 (which is figured by Reeve), and which came to Cuming's collection 

 from the Paris Museum. It is not certain whether Hupe's jussieui 

 is that of Valenciennes or not. Hupe"'s localities are frequently 

 open to suspicion, doubtless owing to careless labelling on the part 

 of the collectors who went to South America with Count Castelnau.
