several diflFerent 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. Rosalina Parkinsoniana (For. Cuba, 

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

 variety.

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.
