I liave not been able to see Gould's description ; but as Mr. 

 Nuttall informs me that this shell is plentiful at Sta. Barbara 

 and as his specimens are even more like the W. Indian ones 

 than the Mazatlan shells are, I presume that the S. mini'ata is a 

 further development of the theory which produced T. simulans, 

 C. B. Ad. It appears to be a very widely diffused species, 

 being one of the very few found JN". and S, of the Gulf of Cali- 

 fornia, and spreading through the Atlantic ocean probably to 

 the Mediterranean and Euxine. Valves have been thrown up 

 on our own shores. The Mazatlan specimens are generally 

 much paler than the W. Indian-, but some have as deep a tinge. 

 The character of the markings is exactly alike, though they 

 vary among themselves in the crowding of the stria?, &c. They 

 are occasionally marked with a yellowish tinge, and are gen- 

 erally more or less stained with black, probably from the mud 

 in which they lived. The shell appears to differ from T. sin- 

 cera, Hani., found by C. B. Ad. at Panama, (rare.) Hani, gives 

 it as from IN". W. Coast of America on the authority of Dr. Sin- 

 clair ; but Nuttall's Californian specimens are undoubtedly 

 T. carnaria. Long. *9, lat. '98, alt. "42.
