Mr. Angas always returned this species named as Clan- 

 culm rubens of A. Adams. There was no such species as 

 Clanculus rubens ever described by A. Adams. Mr. Angas 

 was the first who published the name in Proceedings of the 

 Zoological Society of London, 1865, p. 178. 



The first record of its being described was by Koch, in 1843, 

 as Trochus {Monodonta) Dunkeri. The specimen figured by 

 Fischer in Kiener's Coquilles Vivantes was from specimens 

 sent by Angas to Monsieur Crosse in Paris.
