The exterior markings resemble those of the recent shell, but the 

 upper part of the outer lip is more elevated. My fossil has lost a 

 considerable portion of its canal, which makes it appear shorter, while 

 the lines of growth indicate a length very nearly equal to that of the 

 reticulata ; it may possibly be a new species, but the condition of my 

 single specimen is insufficient for such determination ; as it is a rare 

 shell, I have given a figure. Pi. V. f. 17.

 The mouths of all my specimens are broken. 

 1 . Voluta ? Lamberti, Sow. {Min. Con. 1. 1 29. Mitra Lamberti, Flem. 

 Brit. An. p. 333). 



Ramsholt. | Sutton. | | 



The inhabitant of this shell, in all probability, differed from the true 

 Volutes. It may constitute the type of a new genus ; the want of 

 an emarginated base will remove it from Voluta, and its mammiUated 

 apex from Fasicolaria.

1. Trivia avellana (Cyprsea avellana, Min. Con. t. 378. f. 3).

2. — testudinella, n. s. 



Sutton. I WaltonNaze. | | 



This is intermediate between avellana and affinis, and is exceed- 

 ingly varia1)le ; specimens ranging in size from eleven-sixteenths of 

 an inch (axis) to some scarcely one-fourth ; ridges varying from as 

 many as forty upon the exterior to one that has only twenty-four. 



3. — affinis ?

Only three specimens, and those appear like monstrosities, pro- 

 bably varieties of the preceding.
