The specific identity of shells belongiug to this type frotn different 

 faunas, is not yet decided. As compared with the W. Mexican 

 shells {N. Pritchardi, Forbes, = N. Chemnitzii, Pfr.), the Califor- 

 nian specimens are rather more coarse-grained and solid, with the 

 parietal callosity stronger under the suture. The operculura is 

 thicker, with the margiu less turned-up in proportion. Colour 

 orange-brown, sometimes obscurely banded.

The genus Glandinaria appears to have been proposed (not pub- 

 lished) by Mr. Nuttall, in ignorance of the establishment of Olivella 

 by D'Orbigny, with which it exactly coincides. The name is re- 

 tained for the very well marked species, in preference to the ill-used 

 Californica.

Conrad says this species may be readily distinguished from P. 

 aperta, but does not say how. Dr. Jay considers the two identical ;
