Hanley showed in his revievp of the Linnean shells in 1855 that the 

 original Anomia caput-serpentis of Linnaeus in 1758 is a fossil smooth 

 Terebratuloid, probably from the Italian Tertiary, \yhile the recent 

 shell we have been accustomed to call caput-serpentis is described in 

 the same publication two pages earlier under the name retusa. It is 

 perfectly obvious that the name caput-serpentis is excluded from use 

 in the latter connection by all rules. Those who retain some skep- 

 ticism will do well to consult Hanley's book. 



It appears that the spiculation of the Mediterranean form differs 

 from that of the North of Europe species and Blochmann confirms 

 the opinion of Davidson that the former should be regarded as distinct.
