KANELLA.— Plate II. 



extreme care taken by Mr. Broderip eighteen years since 

 to distinguish them. In the 'Zoological Journal' for 

 1S2G, the two species are not only described by that 

 accomplished writer with the most elaborate pains, but 

 figured with great accuracy side by side, to exhibit their 

 listinctness by comparison. Carelessness in scientific 

 observation engenders endless confusion, and I venture 

 to caution M. Kiener lest he fall into the same estima- 

 tion with his countrymen, as Mr. Perry has done with 



>ui own.

The California!* Ranella. Shell acuminately ovate, 

 large, rather solid, ventricose, varices very strongly 

 tubercled ; whorls angulated, armed with rather 

 distant large solid tubercles, transversely striated, 

 slightly granulated, obsoletely wrinkled next the 

 suture ; whitish, variegated with yellowish chestnut 

 and encircled with rather distant narrow interrupted 

 chestnut bands ; columella faintly wrinkled ; canal 

 very short, rather broad ; aperture large, interior 

 white ; lip crenated, deeply sinuated at the upper 

 part.

This fine shell approximates so closely to the Ranella 

 ventricosa (Sp. 6'.), that it presents to all appearance the 

 same characters, merely, more fully developed and in 

 more gigantic proportion ; several specimens however 

 were collected of the same uniform size and boldness of 

 structure, with the columella slightly wrinkled, and with 

 the tubercles on the spire larger and fewer in number 

 than in that species.
