* "Neocoinien," d'Orbigny, "Jurassic," B. fcQ. Mr. Conrad proposed a new 

 genus to receive this curious and beautiful species, which he called Litkotrochits. 

 It was accidentally omitted at the proper place in this enumeration. After care- 

 fully studying a very fine specimen in my own collection from near Copiapo, 

 Chili, I am unable to detect any valid characters by means of which it can be 

 separated from Turritella, although its wide whorls and low spire induced Von 

 Buch to consider it a Pleurotomaria.
