2=Strigilla miniata, Gould’s plates. 
T have 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 8. miniata is a 
further development of the theory which produced T. simulans, 
C. B. Ad. Vt appears to be a very widely diffused species, 
being one of the very few found N. and 8, 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 strie, &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, Hanl., found by C. B. Ad. at Panama, (rare.) Hanl. gives 
it as from N. 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.
