Genus SOLENOSTEIRA Dall. 



Solenosteira inornata Dall. 



Plate 20, figure 17. 



Part I., p. 123, 1890. 



Older Miocene of the Tampa limestone, banks of the Hillsboro' River, 

 near Tampa, Florida, Dall. 



A figure illustrating this species is given as derived from a restoration for 

 which several gutta-percha casts served as a basis. 



Genus FUSUS Lamarck. 

 Fusus equalis Emmons. 



Plate 14, figure 3 b. 



Part I., p. 126, 1S90. 



The reference to Alum Bluff should be erased. The specimens obtained 

 from Alum Bluff were referable to Fusiis exilis Conrad, and the reference was 

 due to an accidental substitution of one nanie for the other in the manuscript. 



A typical specimen of /^ equalis is figured from the Duplin Natural Well, 

 N. Carolina, for comparison with the following related species : 



Fusus caloosaensis Heilprin. 



Plate 14, figures 3, 4 a. 



Part I., p. 127, 1890. 



This species was not figured in Part I. of this report through an acci- 

 dent by which the figure was unavailable. A new figure has been made 

 from a typical specimen from the Caloosahatchie Pliocene, and another illus- 

 trating the short variety, carolinensis, from the Pliocene of the Waccamaw 

 beds at Tilly's Lake, South Carolina, collected by Mr. C. W. Johnson. 



These extremes are connected by intermediate specimens and illustrate a 

 peculiarity which has several times attracted the writer's attention — namely, 

 that in a long (North and South) meridional geographical series, both in re- 

 cent and fossil species of this group on the Atlantic coast of the United 

 States, the northern specimens tend to vary in the direction of a short and 

 stout form, and the southern ones in the opposite direction. 



This is doubtless due to something in the environment — food, tempera- 

 ture or other factor as yet unknown — but the fact is worthy of attention. 



Fusus quinquespinus Dall. 

 Plate 20, figure S. 

 Part I., p. 128, 1S90. 

 No better material having come to hand, the best of the Ballast Point 

 pseudomorphs has been figured to illustrate this puzzling form.
