THE SMALLER SEA-SHELLS

that is changed; and while we naturally call the 

 recently announced name as a "new" one, still, in 

 most cases it is really an older name than the one 

 that has been in common use for nearly a century. 

 We may doubt the wisdom of restoring these nearly 

 forgotten names, but wiser men than we are have 

 thought differently, and so we bow loyally to their 

 decision. For those who are learning the names 

 for the hrst time the difference will not be appreci- 

 ated. While acting conservatively in this matter, 

 it is proper to remark that other names may be 

 changed, which for the present we have thought it 

 best to retain. 



We begin our descriptions 

 with a rare species, Miirex 

 carpenteri^ Dall, Carpenter's 

 Murex, shown in Figure 15^. 

 The picture is of about the 

 natural size of a large speci- 

 men, and it clearly shows the 

 main features of the shell. 

 The aperture is small, oval, 

 and has an elevated rim with- 

 out denticulations. The color 

 varies from reddish brown to 

 a light gray. There are three Fig. i55(*) 



wing-like varices on each 



whorl, and between them the shell is nearly smooth. 

 This fine species has been found at Monterey, and 

 has also been dredged in various places southward 

 from the Farallone Islands.
