On Hilgendorf's authority (1. a), we learn that Cancer clypeatus Herbst (1794) is 

 not identical with Latreille's Cceiwbita cly peata (1826) but is the same as Cœnobita 

 diogeiies M.-Edw. (1837). It then follows that the proper designation for the last men- 

 tioned species should be Cœnobita clypeatus (Herbst). Since, now, this C. clypeatus 

 (Herbst) is clearly a species distinct from C. clypea/a Latr., the latter must receive a 

 new specific name. Consequently I have proposed to call it Cœnobita Jiilgendorfi.
