This species is similar in sculpture to M. scrobiculatus, 

 from which it differs considerably in form, the spire being 

 long and turreted, and the rostrum elongated and slightly 

 recurved. In form the shell is somewhat similar to the 

 British Trophon muricatus, and would have appeared to 

 belong rather to the genus Trophon than to Murex, but 

 that it has evident affinity with the four last-named species, 

 which appear to belong to the genus or sub-genus Ocinebra, 

 or perhaps it may be found, when the animals are known, 

 that these five species form a separate group.
