The inscribed Olive. Shell cylindrically oblong, 

 rather broad posteriorly, spire acuminate but de- 

 pressed, eolumellar plaits small, numerous ; yellowish,

Hab. . ? 



Very closely resembling O. lilerala in its style of 

 ))ainting, but umforuily of smaller size, and less elongately 

 acuminated. The shell is broader beneath the sutures, 

 the spire being a little depressed, aud has more the form 

 of O. iiiMUdina.

 however, described by Lamarck, and figured some years 

 before by Chemnitz in a plate of miscellaneous nn-named 

 Olives which he termed remarkable varieties, " variidalfs 

 notabiles OliffP." It belongs to the 0. rdiculata type, 

 and is characterized by numerous long flexuous markings 



which may or may not be the outer natural coating of the 

 sjiecies.

The tumid Olive. Shell ovate, thick, ponderous, stout 

 and swollen posteriorly, spii-e rather short, obtuse at 

 the apex, eolumellar plaits numerous, short, anterior

It is not ilifBcult to connect this Olive, as well as 0. 

 Jididu, with 0. rdiculata, in both of which forms the net- 

 work of the typical species is broken uji into a confusion 

 of dots and dashes.
