1 . Pyrula reticulata? Lamarck (Hist, des An. sans Verteb. t. vii. p. 141 . 



Ency.Meth. pi. 432. f. 2). 



Ramsholt. | | | East Indies. 



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. 

 1 . Mitra plicifera, n. s. 

 Sutton. | 



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 mammillated 

 apex from Fasicolaria. 



Section a. with dorsal sulcus. 

 L Trivia avellana (Cypraea avellana, Min. Con. t. 378. f. 3). 



| Sutton. | j 



2. — testudinella, n. s. 



Sutton. | WaltonNaze. | | 

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

 ingly variable ; 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 } 



Sutton, j Sutton. | 

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

 bably varieties of the preceding.
