base of the chambers, and extend above the middle of each. 

 The worthy Tuscan naturalist's collection seems to have been 

 rich in ornamental and odd-growing varieties. The speci- 

 men he has here chosen for delineation has a little abortive 

 terminal chamber, Kke a pinnacle, surmounting those formed 

 on the normal plan. Nodosaria Soldanii differs from N. semi- 

 striata in having the upper third of the chambers smooth, 

 whilst the latter has its costse confined to the upper portion.

Hah. " Fossil near Sienna." 



A Dentaline or curved Nodosarian, long, slider, and many- 

 chambered. The segments are regular and elliptical, and are 

 furnished on their exterior with delicate parallel longitudinal 

 striae. (Fig./ is copied.) 



18. Nodosaria Jlexuosa, D'Orb. PI. IX. fig. 53.

Hah. No locality given by D'Orbigny. (Fossil near Sienna, 

 Soldani.) 



It may be worth while to recognize this variety as Denta- 

 lina Jlexuosa. The figure represents a very slightly curved, 

 deep-sutm'ed, semistriate form, the stride marking the upper 

 third of each chamber.

^^ Hah. Fossil at Coroncina, Italy." (San Quirico, Soldani.) 



A small striate Nodosaria^ deeply constricted at its septa, 

 and having few, distinct, oval or fusiform segments. A less 

 robust form than N. scalaris^ and less neatly finished as to 

 base and terminal neck than that species generally is.

" Hah. Kecent in the Adriatic." (Mediterranean or Adriatic,

The common smooth type of the subgenus, equally abun- 

 dant in the recent and fossil condition. We have endeavoured 

 to tabulate the names under which it has been alluded to by
