several different names in the course of the 'Tableau des Cepha- 

 lopodes.' Thus the Model now under consideration (74) is the 

 ordinary European form ; Rotalina Corallinarum (Model no. 75) 

 is the more fully developed West-Indian variety, which is a still 

 better type; and R. tortuosaf (page 275, no. 40) is the form 

 common in the Adriatic. Rosalind Parkinsoniana (For. Cuba, 

 p. 99, pi. 4. figs. 25-27) is another name given to an Atlantic 

 variety.

Hab. Atlantic, coast of Bellisle. PI. II. fig. 75. 



A convenient subspecies, intermediate between P. Mediterra-

 Page 280, no. 2, pi. 14. figs. 4-6 bis. 



Hab. Mediterranean, attached to various bodies. PI. II. 

 fig. 74. 



D'Orbigny subsequently altered the name of this form (For. 

 Cuba, p. 85, pi. 6. f. 11—13) to Planorbulina vulgaris, because 

 he found that the species was not peculiar to the Mediterranean. 

 Such a change seems contrary to rule ; so we adhere to the 

 original trivial name.
