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

 The wortliy 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, like a pinnacle, surmounting those fomied 

 on tlie normal plan. Nodosaria SoManii 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, slender, and many- 

 chambered. The segments are regular and elli})ticalj and are 

 furnished on their exterior with delicate parallel longitudinal 

 striso. (Fig./ is copied.)

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



Soldani.) 



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

 lina Jlexuosa. The figure represents a very slightly curved, 

 deep-sutured, semistriate form, the striie marking the upper 

 third of each chamber.

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



A small striate Nodosaria, deeply constricted at its sc])ta, 

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

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

 base and terminal neck than that species generally is.
