DALL, TERTIARY MOLLUSKS OF FLORIDA, PART II. 



PLATE XIII. 



Note. — The figures immediately preceding ttie page-reference represent the actual 

 length in millimeters of the longest dimension of the object as seen in the figure. The 

 drawings were made at different times and with the view of bringing out the characters of 

 each specimen distinctly, rather than with that of their being strictly comparable in size 

 among themselves. Thus it has happened that the real sizes of the specimens bear no 

 constant relation to the size of the figures, and a smaller species may be represented by a 

 figure larger than that of a larger fossil. The numerals in the reference, therefore, except 

 where otherwise stated, give the exact length of the greatest dimension, whether breadth 

 or height, and enable one to compare the sizes without having to refer back to the descrip- 

 tion in the text. The plates are numbered continuously with those of Part I. Plate 23, to 

 which references occur in the text, will be published in Part III., which will conclude the 

 work.
