ADDITIONS AND CORRECTIONS. 



Since the preceding pages were stereotyped, the following additions and correc 

 tions have been obtained from my friends Messrs. Tryon and Stearns, who have 

 examined the proof sheets. I have also detected two or three omissions, which are 

 here corrected. 



TROPHON squamulifer, Cpr. Found by Mr. Stearns, living at Monterey and 

 Catalina Island ; common. 



NEPTUNE A lirata, Mart., Alaska; a large series has been compared by Stearns 

 and Morse with N. decemcostata, and they consider them identical; circumboreal. 



MARGARITA salmonea, Cpr. " Is not worth a variety distinction from pupilla." 

 (Stearns.) 



CLYFIDELLA bimaculata, Dall. Is now considered by Stearns and Carpenter, to 

 be identical with caUomarginata, after a comparison of a large suite of shells and 

 animals.
