? = Strigilla miniata, Gould's plates. 



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

 Nuttall informs me that this shell is plentiful at Sta . Bai'bara 

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

 than the Mazatlan shells are, I presume that the S. miniata 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 N. 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 Mazatlau specimens are generally 

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

 The character of the markmgs 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 wliicli 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 N. W. Coast of America on the authority of Dr. Sin- 

 clair ; but Nuttall's Californian specmiens are undoubtedly 

 T. carnaria. Long. "9, hit. '98, alt. '42.
